APPLICATION HIGHLIGHTS
offset current is 1.0 nA. The top grade is the first bipolar 1. The AD707’s 13 V/µV typical open-loop gain and 140 dB monolithic op amp to offer a maximum offset voltage drift of typical common-mode rejection ratio make it ideal for 0.1 µV/°C, and offset current drift and input bias current drift precision instrumentation applications. are both specified at 25 pA/°C maximum. 2. The precision of the AD707 makes tighter error budgets The AD707’s open-loop gain is 8 V/µV minimum over the full possible at a lower cost. ±10 V output range when driving a 1 kΩ load. Maximum input 3. The low offset voltage drift and low noise of the AD707 allow voltage noise is 350 nV p-p (0.1 Hz to 10 Hz). CMRR and the designer to amplify very small signals without sacrificing PSRR are 130 dB and 120 dB minimum, respectively. overall system performance. The AD707 is available in versions specified over commercial, 4. The AD707 can be used where chopper amplifiers are industrial and military temperature ranges. It is offered in 8-pin required, but without the inherent noise and application plastic mini-DIP, small outline (SOIC), hermetic cerdip and problems. hermetic TO-99 metal can packages. Chips, MIL-STD-883B, 5. The AD707 is an improved pin-for-pin replacement for the Rev. C, and tape & reel parts are also available. LT1001. REV.
