Input offset votage is trimmed to ess than 15μV and the ow drift maintains this accuracy over the operating temperature range. Input bias current is an utraow 9 maximum. The ampifi er works on any tota power suppy votage between 2.7V and 36V (fuy specified from 5V to ±15V). Output votage swings to within 55 of the negative suppy and 25 of the positive suppy, which makes the ampifier a good choice for ow votage singe suppy operation. Sew rates of.4v/μs with a suppy current of 1.2 give superior response and setting time performance in a ow power precision ampifier. The LT188 is avaiabe in a 5-ead SOT-23 package.

8 LT188 APPLICATIONS INFORMATION The LT188 singe op amp features exceptiona input precision with rai-to-rai output swing. Sew rate and sma signa bandwidth are superior to other ampifi ers with comparabe input precision. These characteristics make the LT188 a convenient choice for precision ow votage systems and for improved AC performance in higher votage precision systems. Obtaining beneficia advantage of the precision inherent in the ampifier depends upon proper appications circuit design and board ayout. Preserving Input Precision Preserving the input votage accuracy of the LT188 requires that the appications circuit and PC board ayout do not introduce errors comparabe to or greater than the 4μV offset. Temperature differentias across the input connections can generate thermocoupe votages of 1 s of microvots. PC board ayouts shoud keep connections to the ampifier s input pins cose together and away from heat dissipating components. Air currents across the board can aso generate temperature differentias. The extremey ow input bias currents, 15, aow high accuracy to be maintained with high impedance sources and feedback networks. The LT188 s ow input bias currents are obtained by using a canceation circuit on-chip. This causes the resuting I BIAS and I BIAS to be uncorreated, as impied by the OS specifi cation being comparabe to IAS. The user shoud not try to baance the input resistances in each input ead, as is commony recommended with most ampifi ers. The impedance at either input shoud be kept as sma as possibe to minimize tota circuit error. PC board ayout is important to insure that eakage currents do not corrupt the ow IAS of the ampifier. In high precision, high impedance circuits, the input pins shoud be surrounded by a guard ring of PC board interconnect, with the guard driven to the same common mode votage as the ampifi er inputs. Input Common Mode Range The LT188 output is abe to swing neary to each power suppy rai, but the input stage is imited to operating between V 1V and V 1.2V. Exceeding this common mode range wi cause the gain to drop to zero, however no gain reversa wi occur. 8 Input Protection The inverting and noninverting input pins of the LT188 have imited on-chip protection. ESD protection is provided to prevent damage during handing. The input transistors have votage camping and imiting resistors to protect against input differentias up to 1V. Short transients above this eve wi aso be toerated. If the input pins can see a sustained differentia votage above 1V, externa imiting resistors shoud be used to prevent damage to the ampifier. A 1k resistor in each input ead wi provide protection against a 3V differentia votage. Capacitive Loads The LT188 can drive capacitive oads up to 6pF in unity gain. The capacitive oad driving capabiity increases as the ampifier is used in higher gain configurations, see the graph abed Capacitive Load Response. Capacitive oad driving may be increased by decouping the capacitance from the output with a sma resistance.

Figure 1 shows the basic op amp configurations, what happens to the op amp inputs, and whether or not the op amp must have raito-rai inputs. 188fa

Some Op Amp Confi gurations Do Not Require Rai-to Rai Inputs to Achieve Rai-to-Rai Outputs The circuit of Figure 2 shows an extreme exampe of the inverting case. The input votage at the 1M resistor can swing ±13.5V and the LT188 wi output an inverted, divided-by-ten version of the input votage. The input accuracy is imited by the resistors to.2%. Output referred, this error becomes 2.7. The 4μV input offset votage contribution, pus the additiona error due to input bias current times the ~1k effective source impedance, contribute ony negigiby to error. ±13.5V SWINGS WELL OUTSIDE SUPPLY RAILS V IN 1M,.1% 1k,.1% 1.5V LT188 ±1.35V OUTPUT SWING Precision Photodiode Ampifier Photodiode ampifiers usuay empoy JFET op amps because of their ow bias current; however, when precision is required, JFET op amps are generay inadequate due to their reativey high input offset votage and drift. The LT188 provides a high degree of precision with very ow bias current ( = 15 typica) and is therefore appicabe to this demanding task.

10 LT188 APPLICATIONS INFORMATION The transimpedance gain is set to 51.1kΩ by R F. The feedback capacitor, C F, may be as arge as desired where response time is not an issue, or it may be seected for maximay fat response and highest possibe bandwidth given a photodiode capacitance C D. Figure 4 shows a chart of C F and rise time versus C D for maximay fat response. Tota output offset is beow 262μV, worst-case, over temperature ( C to 7 C). With a 5V output swing, this guarantees a minimum 86dB dynamic range over temperature ( C to 7 C), and a fu-scae photodiode current of 98μA. Singe-Suppy Current Source for Patinum RTD The precision, ow bias current input stage of the LT188 makes it idea for precision integrators and current sources. Figure 5 shows the LT188 providing a simpe precision current source for a remote 1kΩ RTD on a 4-wire 1 connection. The LT1634 reference paces 1.25V at the noninverting input of the LT188, which then maintains its inverting input at the same votage by driving 1 of current through the RTD and the tota 1.25kΩ of resistance set by R1 and R2. Imprecise components R4 and C1 ensure circuit stabiity, which woud otherwise be excessivey dependant on the cabe characteristics. R5 is aso noncritica and is incuded to improve ESD immunity and decoupe any cabe capacitance from the LT188 s output. The 4-wire cabe aows Kevin sensing of the RTD votage whie excuding the cabe IR drops from the votage reading. With 1 excitation, a 1kΩ RTD wi have 1V across it at C, and 3.85/ C temperature response. This votage can be easiy read in myriad ways, with the best method depending on the temperature region to be emphasized and the particuar ADC that wi be reading the votage.
