lt1057/lt1058 1 10578fd typical application features applications description dual and quad, jfet input precision high speed op amps the lt ? 1057 is a matched jfet input dual op amp in the industry standard 8-pin coniguration, featuring a combination of outstanding high speed and precision speciications. it replaces all the popular bipolar and jfet input dual op amps. in particular, the lt1057 upgrades the performance of systems using the lf412a and op-215 jfet input duals. the lt1058 is the lowest offset quad jfet input operational ampliier in the standard 14-pin coniguration. it offers signiicant accuracy improvement over presently available jfet input quad operational ampliiers. the lt1058 can replace four single precision jfet input op amps, while saving board space, power dissipation and cost. both the lt1057 and lt1058 are available in the plastic pdip package and the surface mount so package. current output, high speed, high input impedance instrumentation ampli?er n 14v/s slew rate: 10v/s min n 5mhz gain-bandwidth product n fast settling time: 1.3s to 0.02% n 150v offset voltage (lt1057): 450v max n 180v offset voltage (lt1058): 600v max n 2v/c v os drift: 7v/c max n 50pa bias current at 70c n low voltage noise: 13nv/ hz at 1khz 26nv/ hz at 10hz n precision, high speed instrumentation n fast, precision sample-and-hold n logarithmic ampliiers n d/a output ampliiers n photodiode ampliiers n voltage-to-frequency converters n frequency-to-voltage converters , lt, ltc and ltm are registered trademarks of linear technology corporation. all other trademarks are the property of their respective owners. distribution of offset voltage (all packages, lt1057 and lt1058) C + C + C + C + 6.8k 7.5k r x 7.5k 1/4 lt1058 1/4 lt1058 1/4 lt1058 1/4 lt1058 1 32 v2 i out i out = 2(v1 C v2) r x v1 *gain adjust **common mode rejection adjust bandwidth 2mhz 65 7 10 14 1312 9 8 4.7k 500* 1k** 4.7k 7.5k 9.1k 10578 ta01 input offset voltage (mv) C1.0 percent of units 15 20 25 0.6 10578 ta01b 10 5 0 C0.6 C0.2 0 0.2 1.0 v s = 15v t a = 25 c lt1057: 610 op ampslt1058: 520 op amps 1130 op amps tested downloaded from: http:///

lt1057/lt1058 9 10578fd settling time is measured in a test circuit which can be found in the lt1055/lt1056 data sheet and in application note 10. achieving picoampere/microvolt performance in order to realize the picoampere/microvolt level accuracy of the lt1057/lt1058, proper care must be exercised. for example, leakage currents in circuitry external to the op amp can signiicantly degrade performance. high quality insulation should be used (e.g., telon tm , kel-f); cleaning of all insulating surfaces to remove luxes and other resi - dues will probably be required. surface coating may be necessary to provide a moisture barrier in high humidity environments. board leakage can be minimized by encircling the input circuitry with a guard ring operated at a potential close to that of the inputs; in inverting conigurations, the guard ring should be tied to ground, in noninverting connections, to the inverting input. guarding both sides of the printed circuit board is required. bulk leakage reduction depends on the guard ring width. the lt1057/lt1058 have the lowest offset voltage of any dual and quad jfet input op amps available today. however, the offset voltage and its drift with time and temperature are still not as good as on the best bipolar ampliiers (because the transconductance of fets is considerably lower than that of bipolar transistors). conversely, this lower trans - conductance is the main cause of the signiicantly faster speed performance of fet input op amps. offset voltage also changes somewhat with temperature cycling. the am grades show a typical 40v hysteresis (50v on the m grades) when cycled over the C55c to 125c temperature range. temperature cycling from 0c to 70c has a negligible (less than 20v) hysteresis effect. the offset voltage and drift performance are also affected by packaging. in the plastic n package, the molding com - pound is in direct contact with the chip, exerting pressure on the surface. while npn input transistors are largely unaffected by this pressure, jfet device drift is degraded. consequently for best drift performance, as shown in the typical performance characteristics distribution plots, the j or h packages are recommended. in applications where speed and picoampere bias currents are not necessary, linear technology offers the bipolar input, pin compatible lt1013 and lt1014 dual and quad op amps. these devices have signiicantly better dc speciications than any jfet input device. phase reversal protection most industry standard jfet input single, dual and quad op amps (e.g., lf156, lf351, lf353, lf411, lf412, op-15, op-16, op-215, tl084) exhibit phase reversal at the output when the negative common mode limit at the input is exceeded (i.e., below C12v with 15v supplies). the photos below show a 16v sine wave input (a), the response of an lf412a in the unity gain follower mode (b), and the response of the lt1057/lt1058 (c). the phase reversal of photo (b) can cause lock-up in servo systems. the lt1057/lt1058 does not phase-reverse due to a unique phase reversal protection circuit. applications information all photos 5v/div vertical scale, 50s/div horizontal scale (a) 16v sine wave input (b) lf412a output (c) lt1057/lt1058 output t e?on is a trademark of dupont. downloaded from: http:///
