OP42S: Aerospace High Speed, Fast Settling Precision JFET-Input
The OP42 is a fast precision JFET-input operational amplifier. Similar in speed to the OP17, the OP42 offers a symmetric 58V/us slew rate and is internally compensated for unity-gain operation. OP42 speed is achieved with a supply current of less than 6mA. Unity gain stability, a wide full-power bandwidth of 900kHz, and a typical fast settling-time of 800ns to 0.01% make the OP42 an ideal output amplifier for fast digital-to-analog converters. Equal attention was given to both speed and precision in the OP42 design.
Its tight 750uV maximum input offset voltage combined with well-controlled drift of less than 10uV/%C eliminates the need for external nulling in many circuits. The common-mode rejection of the 86dB minimum over a ±11 V input voltage range is exceptional for a high-speed amplifier. High CMR combined with a minimum 500V/mV gain into 10k(ohm) load ensure excellent linearity in both noninverting and inverting gain configurations. The low input bias and offset currents provided by the JFET input stage suit the OP42 for use in high-speed sample and hold circuits, peak detectors, and log amplifiers. Excellent radiation hardness characteristics make the OP42 ideal for military and aerospace applications.
The OP42 conforms to the standard 741 pinout with nulling to V-. The OP42 upgrades the performance of circuits using the AD544, AD611, AD711, and LF400 by direct replacement. In circuits without nulling, the OP42 offers an upgrade for designs using the OP16, OP17, LT1022, and LT1056.
