LT63/LT63 3MHz, V/µs, Dua/Quad Rai-to-Rai Input and Output Precision Op Amps Description The LT 63/LT63 are dua/quad, rai-to-rai input and output op amps with a 3MHz gain-bandwidth product and a V/µs sew rate. The LT63/LT63 have exceent DC precision over the fu range of operation. Input offset votage is typicay ess than 5 and the minimum open-oop gain of one miion into a k oad virtuay eiminates a gain error. To maximize common mode rejection, the LT63/LT63 empoy a patented trim technique for both input stages, one at the negative suppy and the other at the positive suppy, that gives a typica CMRR of 6 over the fu input range. The LT63/LT63 maintain their performance for suppies from 2.7V to 36V and are specified at 3V, 5V and ±5V suppies. The inputs can be driven beyond the suppies without damage or phase reversa of the output. The output deivers oad currents in excess of 35mA. The LT63 is avaiabe in 8-pin PDIP and SO packages with the standard dua op amp pinout. The LT63 features the standard quad op amp configuration and is avaiabe in a 4-pin pastic SO package. These devices can be used as pug-in repacements for many standard op amps to improve input/output range and performance.

Figure shows a simpified schematic of the ampifier. The input stage consists of two differentia ampifiers, a PNP stage Q/Q2 and an NPN stage Q3/Q4 that are active over different ranges of input common mode votage. The PNP differentia input pair is active for input common mode votages V CM between the negative suppy to approximatey.4v beow the positive suppy. As V CM moves coser toward the positive suppy, the transistor Q5 wi steer the tai current I to the current mirror Q6/Q7, activating the NPN differentia pair and the PNP pair becomes inactive for the rest of the input common mode range up to the positive suppy. The output is configured with a pair of compementary common emitter stages Q4/Q5 that enabes the output to swing from rai to rai. These devices are fabricated on Linear Technoogy s proprietary compementary bipoar process to ensure simiar DC and AC characteristics. Capacitors C and C2 form oca feedback oops that ower the output impedance at high frequencies. 63fa

LT63 Simpified Schematic Diagram Power Dissipation The LT63/LT63 ampifiers combine high speed and arge output current drive in a sma package. Because the ampifiers operate over a very wide suppy range, it is possibe to exceed the maximum junction temperature of 5 C in pastic packages under certain conditions. Junction temperature, T J, is cacuated from the ambient temperature, T A, and power dissipation, P D, as foows: LT63CN8: T J = T A (P D 3 C/W) LT63CS8: T J = T A (P D 9 C/W) LT63CS: T J = T A (P D 5 C/W) The power dissipation in the IC is the function of the suppy votage, output votage and oad resistance. For a given suppy votage, the worst-case power dissipation P DMAX occurs at the maximum suppy current and when the output votage is at haf of either suppy votage (or the maximum swing if ess than /2 suppy votage). Therefore P DMAX is given by: P DMAX = (V S I SMAX ) (V S /2)2/R L To ensure that the LT63/LT63 are used propery, cacuate the worst-case power dissipation, get the therma resistance for a chosen package and its maximum junction temperature to derive the maximum ambient temperature. Exampe: An LT63CS8 operating on ±5V suppies and driving a 5Ω, the worst-case power dissipation per ampifier is given by: P DMAX = (3V 4.75mA) (5V 7.5V)(7.5/5) =.43.3 =.6W If both ampifiers are oaded simutaneousy, then the tota power dissipation is.52w. The SO-8 package has a junction-to-ambient therma resistance of 9 C/W in sti air. Therefore, the maximum ambient temperature that the part is aowed to operate is: T A = T J (P DMAX 9 C/W) T A = 5 C (.52W 9 C/W) = 53 C For a higher operating temperature, ower the suppy votage or use the DIP package part. 63fa 5

16 LT63/LT63 Appications Information Input Offset Votage The offset votage changes depending upon which input stage is active, and the maximum offset votages are trimmed to ess than 5. To maintain the precision characteristics of the ampifier, the change of V OS over the entire input common mode range (CMRR) is guaranteed to be ess than 5 on a singe 5V suppy. Input Bias Current The input bias current poarity depends on the input common mode votage. When the PNP differentia pair is active, the input bias currents fow out of the input pins. They fow in the opposite direction when the NPN input stage is active. The offset votage error due to input bias currents can be minimized by equaizing the noninverting and inverting input source impedance. Output The outputs of the LT63/LT63 can deiver arge oad currents; the short-circuit current imit is 7mA. Take care to keep the junction temperature of the IC beow the absoute maximum rating of 5 C (refer to the Power Dissipation section). The output of these ampifiers have reverse-biased diodes to each suppy. If the output is forced beyond either suppy, unimited current wi fow through these diodes. If the current is transient and imited to severa hundred ma, no damage to the part wi occur. Overdrive Protection To prevent the output from reversing poarity when the input votage exceeds the power suppies, two pairs of crossing diodes D to D4 are empoyed. When the input votage exceeds either power suppy by approximatey 7, D/D2 or D3/D4 wi turn on, forcing the output to the proper poarity. For this phase reversa protection to work propery, the input current must be imited to ess than 5mA. If the ampifier is to be severey overdriven, an externa resistor shoud be used to imit the overdrive current. The LT63/LT63 s input stages are protected against arge differentia input votages by a pair of back-to-back diodes D5/D6. When a differentia votage of more than.7v is appied to the inputs, these diodes wi turn on, preventing the emitter-base breakdown of the input transistors. The current in D5/D6 shoud be imited to ess than ma. Interna 2Ω resistors R6 and R7 wi imit the input current for differentia input signas of 4.5V or ess. For arger input eves, a resistor in series with either or both inputs shoud be used to imit the current. Worst-case differentia input votage usuay occurs when the output is shorted to ground. In addition, the ampifier is protected against ESD strikes up to 3kV on a pins. Capacitive Load The LT63/LT63 are wideband ampifiers that can drive capacitive oads up to 2pF on ±5V suppies in a unity-gain configuration. On a 3V suppy, the capacitive oad shoud be kept to ess than pf. When there is a need to drive arger capacitive oads, a resistor of 2Ω to 5Ω shoud be connected between the output and the capacitive oad. The feedback shoud sti be taken from the output so that the resistor isoates the capacitive oad to ensure stabiity. Feedback Components The ow input bias currents of the LT63/LT63 make it possibe to use the high vaue feedback resistors to set the gain. However, care must be taken to ensure that the poe formed by the feedback resistors and the tota capacitance at the inverting input does not degrade stabiity. For instance, the LT63/LT63 in a noninverting gain of 2, set with two 2k resistors, wi probaby osciate with pf tota input capacitance (5pF input capacitance and 5pF board capacitance). The ampifier has a 5MHz crossing frequency and a 52 phase margin at 6 of gain. The feedback resistors and the tota input capacitance form a poe at.6mhz that induces a phase shift of 72 at 5MHz! The soution is simpe: either ower the vaue of the resistors or add a feedback capacitor of pf or more. 6 63fa

The Q factor can be adjusted by varying the vaue of R8. The higher vaue of R8 wi decrease Q as depicted in Figure 5, because the output induces ess of feedback to ampifier A2. The vaue of R7 shoud be equa or greater than R9 to prevent osciation. If R8 is a short and R9 is arger than R7, then the positive feedback from the output wi create phase inversion at the output of ampifier A2, which wi ead to osciation.

20 LT63/LT63 Typica Appication RF Ampifier Contro Biasing and DC Restoration Taking advantage of the rai-to-rai input and output, and the arge output current capabiity of the LT63, the circuit, shown in Figure 6, provides precise bias currents for the RF ampifiers and restores DC output eve. To ensure optimum performance of an RF ampifier, its bias point must be accurate and stabe over the operating temperature range. The op amp A combined with Q, Q2, R, R2 and R3 estabishes two current sources of 2.5mA to bias RF and RF2 ampifiers. The current of Q is determined by the votage across R2 over R, which is repicated in Q2. These current sources are stabe and precise over temperature and have a ow dissipated power due to a ow votage drop between their terminas. The ampifier A2 is used to restore the DC eve at the output. With a arge output current of the LT63, the output can be set at.5vdc on 5V suppy and 5Ω oad. This circuit has a 3 bandwidth from 2MHz to 2GHz and a power gain of.
