LT1057S

The LT1057S is a kind of matched JFET input dual operational amplifier. It replaces all the popular bipolar and JFET input dual operational amplifier. In particular, it upgrades the performance of systems using the LF412A and OP-215 JFET input duals. The typical applications include: (1)include precision, high speed instrumentation; (2)fast, precision sample and hold; (3)logarithmic amplifiers; (4)D/A output amplifiers; (5)photodiode amplifiers; (6)voltage to frequency converters; (7)frequency to voltage converters. 

There are some features as follows: (1)13 V/s slew rate and 8 V/s min; (2)5 MHz gain-bandwidth product; (3)fast setting time: 1.3s to 0.02%; (4)300V offset voltage; (5)5V/ VDS drift; (6)60 pA bias current at 70; (7)low voltage noise: 13 nV/HZ at 1 kHz and 26 nV/HZ at 10 kHz.

The following is about the absolute maximum ratings: (1)supply voltage: ±20 V; (2)differential input voltage: ±40 V; (3)input voltage: ±20 V; (4)output short circuit duration: indefinite; (5)operating temperature range: 0 to 70; (6)storage temperature range for all devices: -65 to 150; (7)lead temperature (soldering, 10 sec): 300.
