These ampifiers combine very ow noise and suppy current with a MHz gain bandwidth product, a 25V/µs sew rate, and are optimized for ow suppy signa conditioning systems. These ampifiers maintain their performance for suppies from 2.5V to 2.6V and are specified at 3V, 5V and ±5V suppies. Harmonic distortion is ess than 8c at MHz making these ampifiers suitabe in ow power data acquisition systems. The LT622 is avaiabe in the 5-pin TSOT-23 and the 8-pin SO, whie the LT623 comes in 8-pin SO and MSOP packages with standard op amp pinouts. For compact ayouts the LT623 is aso avaiabe in a tiny fine ine eadess package (DFN), whie the quad LT624 is avaiabe in the 6-pin SSOP and 4-pin SO packages. These devices can be used as pug-in repacements for many op amps to improve input/output range and noise performance.

18 LT622/LT623/LT624 APPLICATIONS INFORMATION Ampifier Characteristics Figure shows a simpified schematic of the LT622/ LT623/LT624, which has two input differentia ampifiers in parae that are biased on simutaneousy when the common mode votage is at east.5v from either rai. This topoogy aows the input stage to swing from the positive suppy votage to the negative suppy votage. As the common mode votage swings beyond V CC.5V, current source I saturates and current in Q/Q4 is zero. Feedback is maintained through the Q2/Q3 differentia ampifier, but with an input g m reduction of /2. A simiar effect occurs with I 2 when the common mode votage swings within.5v of the negative rai. The effect of the g m reduction is a shift in the V OS as I or I 2 saturate. Input bias current normay fows out of the and inputs. The magnitude of this current increases when the input common mode votage is within.5v of the negative rai, and ony Q/Q4 are active. The poarity of this current reverses when the input common mode votage is within.5v of the positive rai and ony Q2/Q3 are active. The second stage is a foded cascode and current mirror that converts the input stage differentia signas to a singe ended output. Capacitor C reduces the unity cross frequency and improves the frequency stabiity without degrading the gain bandwidth of the ampifier. The differentia drive generator suppies current to the output transistors that swing from rai-to-rai.

19 APPLICATIONS INFORMATION Input Protection There are back-to-back diodes, D and D2, across the and inputs of these ampifiers to imit the differentia input votage to ±.7V. The inputs of the LT622/LT623/ LT634 do not have interna resistors in series with the input transistors. This technique is often used to protect the input devices from over votage that causes excessive currents to fow. The addition of these resistors woud significanty degrade the ow noise votage of these ampifiers. For instance, a Ω resistor in series with each input woud generate.8nv/ Hz of noise, and the tota ampifier noise votage woud rise from.9nv/ Hz to 2.6nV/ Hz. Once the input differentia votage exceeds ±.7V, steady state current conducted though the protection diodes shoud be imited to ±4. This impies 25Ω of protection resistance per vot of continuous overdrive beyond ±.7V. The input diodes are rugged enough to hande transient currents due to ampifier sew rate overdrive or momentary cipping without these resistors. Figure 2 shows the input and output waveforms of the ampifier driven into cipping whie connected in a gain of A V =. When the input signa goes sufficienty beyond the power suppy rais, the input transistors wi saturate. When saturation occurs, the ampifier oses a stage of phase inversion and the output tries to change states. Diodes D and D2 forward bias and hod the output within OV Figure 2. V S = ±2.5V, A V = with Large Overdrive LT622/LT623/LT624 a diode drop of the input signa. In this photo, the input signa generator is cipping at ±35, and the output transistors suppy this generator current through the protection diodes. With the ampifier connected in a gain of A V 2, the output can invert with very heavy input overdrive. To avoid this inversion, imit the input overdrive to.5v beyond the power suppy rais. ESD The LT622/LT623/LT624 have reverse-biased ESD protection diodes on a inputs and outputs as shown in Figure. If these pins are forced beyond either suppy, unimited current wi fow through these diodes. If the current is transient and imited to one hundred miiamps or ess, no damage to the device wi occur. Noise The noise votage of the LT622/LT623/LT624 is equivaent to that of a 225Ω resistor, and for the owest possibe noise it is desirabe to keep the source and feedback resistance at or beow this vaue, i.e. R S R G R FB 225Ω. With R S R G R FB = 225Ω the tota noise of the ampifier is: e n = (.9nV) 2 (.9nV) 2 = 2.7nV. Beow this resistance vaue, the ampifier dominates the noise, but in the resistance region between 225Ω and approximatey kω, the noise is dominated by the resistor therma noise. As the tota resistance is further increased, beyond k, the noise current mutipied by the tota resistance eventuay dominates the noise. The product of e n I SUPPLY is an interesting way to gauge ow noise ampifiers. Many ow noise ampifiers with ow e n have high I SUPPLY current. In appications that require ow noise with the owest possibe suppy current, this product can prove to be enightening. The LT622/LT623/LT624 have an e n, I SUPPLY product of 3.2 per ampifier, yet it is common to see ampifiers with simiar noise specifications have an e n I SUPPLY product of 4.7 to 3.5. For a compete discussion of ampifier noise, see the LT28 data sheet fd 9

20 LT622/LT623/LT624 TYPICAL APPLICATIONS Low Noise, Low Power MΩ AC Photodiode Transimpedance Ampifier Figure 3 shows the LT622 appied as a transimpedance ampifier (TIA). The LT622 forces the BF862 utraow-noise JFET source to V, with R3 ensuring that the JFET has an I DRAIN of. The JFET acts as a source foower, buffering the input of the LT622 and making it suitabe for the high impedance feedback eements R and R2. The BF862 has a minimum I DSS of and a pinchoff votage between.3v and.2v. The JFET gate and the LT622 output V BIAS R3 4.99k V S V S PHILIPS BF862 R 499k LT622 R2 499k C pf Figure 3. Low Noise, Low Power MΩ AC Photodiode Transimpedance Ampifier V OUT LT622/3/4 F3 therefore sit at a point sighty higher than one pinchoff votage beow ground (typicay about.6v). When the photodiode is iuminated, the current must come from the LT622 s output through R and R2, as in a norma TIA. Ampifier input noise density and gain-bandwidth product were measured at 2.4nV/Hz and MHz, respectivey. Note that because the JFET has a high g m, approximatey /8Ω, its attenuation ooking into R3 is ony about 2%. Gain-bandwidth product was measured at MHz and the cosed-oop bandwidth using a 3pF photodiode was approximatey.4mhz. Precision Low Noise, Low Power, MΩ Photodiode Transimpedance Ampifier Figure 4 shows the LT622 appied as a transimpedance ampifier (TIA), very simiar to that shown in Figure 3. In this case, however, the JFET is not aowed to dictate the DC-bias conditions. Rather than being grounded, the LT622 s noninverting input is driven by the LTC25 to the exact state necessary for zero JFET gate votage. The noise performance is neary identica to that of the circuit in Figure 3, with the additiona benefit of exceent DC performance. Input offset was measured at under 2µV and output noise was within 2 P-P over a 2MHz bandwidth.

21 TYPICAL APPLICATIONS Singe-Suppy 6-Bit ADC Driver Figure 5 shows the LT623 driving an LTC864 unipoar 6-bit A/D converter. The bottom haf of the LT623 is in a gain-of-one configuration and buffers the V negative fu-scae signa V LOW into the negative input of the LTC864. The top haf of the LT623 is in a gain-of-ten configuration referenced to the buffered votage V LOW and drives the positive input of the LTC864. The input range of the LTC864 is V to 5V, but for best resuts the input range of V IN shoud be from V LOW (about.4v) to about.82v. Figure 6 shows an FFT obtained with a.38khz coherent input waveform, from 892 sampes with no windowing or averaging. Spurious free dynamic range is seen to be about. LT622/LT623/LT624 Athough the LTC864 has a sampe rate far beow the gain bandwidth of the LT623, using this ampifier is not necessariy a case of overki. The designer is reminded that A/D converters have sampe apertures that are vanishingy sma (ideay, infinitesimay sma) and make demands on the upstream circuitry far in excess of what is impied by the innocent-ooking sampe rate. In addition, when an A/D converter takes a sampe, it appies a sma capacitor to its inputs with a fair amount of gitch energy and expects the votage on the capacitor to sette to the true vaue very quicky. Finay, the LTC864 has a 2MHz anaog input bandwidth and can be used in undersamping appications, again requiring a source bandwidth higher than Nyquist.
