Dual Precision, Low Cost, High Speed BiFET Op Amp AD712-EP FEATURES CONNECTION DIAGRAM AMPLIFIER NO. 1 AMPLIFIER NO. 2 Supports defense and aerospace applications (AQEC 1 8 V+ standard) OUTPUT Military temperature range (55C to +125C) INVERTING 2 7 OUTPUT INPUT Controlled manufacturing baseline NONINVERTING INVERTING 3 6 INPUT INPUT One assembly/test site NONINVERTING V 4 5 One fabrication site INPUT AD712-EP Enhanced product change notification Figure 1. 8-Lead SOIC N (R-Suffix) Qualification data available on request Enhanced replacement for LF412 and TL082 AC performance Settles to 0.01% in 1.0 s 16 V/s minimum slew rate 3 MHz minimum unity-gain bandwidth DC performance 150 V/mV minimum open-loop gain Available in a SOIC N package GENERAL DESCRIPTION The AD712-EP is a high speed, precision, monolithic The combination of excellent noise performance and low input operational amplifier offering high performance over the current also make the AD712-EP useful for photodiode preamps. military temperature range of 55C to +125C. Its low offset Common-mode rejection of 88 dB and open-loop gain of voltage and offset voltage drift are the results of advanced laser 400 V/mV ensure 12-bit performance even in high speed unity- wafer trimming technology. These performance benefits allow gain buffer circuits. the user to easily upgrade existing designs that use older The AD712-EP is available in an 8-lead SOIC N package. precision BiFET or bipolar op amps. Additional applications information is available in the AD712 The superior ac and dc performance of this op amp makes it data sheet. suitable for active filter applications. With a slew rate of 16 V/s and a settling time of 1 s to 0.01%, the AD712-EP is ideal as a buffer for 12-bit digital-to-analog converters (DACs) and 12-bit analog-to-digital converters (ADCs) and as a high speed integrator.
