OP-42

The OP-42 is a kind of high speed, fast setting precision JFET-input operational amplifier. Similar in speed to the OP-17, the device offers a symmetric 58 V/s slew rate and is internally compensated for unity-gain operation. The low input bias and offset currents provided by the JFET input stage make it suitable for use in high-speed sample and hold circuits, peak detectors, and log amplifiers. Excellent radiation hardness makes it ideal for military and aerospace applications. The device comforms to the standard 741 pinout with nulling to V-. The OP-42 upgrades the performance of circuits using the AD544, AD611, AD711, and LF400 by direct replacement. In circuits without nulling, the device offers upgrade of designs using the OP-16, OP-17, LT1022, LT1056 and HA2510.

There are some features of OP-42 as follows: (1)fast: slew rate: 50 V/s min; setting time (0.01%): 1s max; gain-bandwidth product: 10 MHz typ; (2)precise: common-mode rejection: 88 dB min; open-loop gain; 500 V/mV min; offset voltage: 750V max; bias current: 200 pA max; (3)excellent radiation hardness; (4)available in Die Form.

The last one is about the absolute maximum ratings of OP-42: (1)supply voltage: ±20 V; (2)input voltage: ±20 V; (3)differential input voltage: 40 V; (4)output short-circuit duration: indefined; (5)storage temperature range: -65 to +175; (6)operating temperature range: OP42A(J, Z): -55 to +125; OP42E, F(J, Z): -25 to +85; OP42G: -40 to +85; (7)junction temperature: -65 to +175; (8)lead temperature range (soldering, 60 sec): +300.
