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

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
± 10 V output range when driving a 1 kΩ load. Maximum input
voltage noise is 350 nV p-p (0.1 Hz to 10 Hz). CMRR and
PSRR are 130 dB and 120 dB minimum, respectively.
possible at a lower cost.
3. The low offset voltage drift and low noise of the AD707 allow
the designer to amplify very small signals without sacrificing
overall system performance.
The AD707 is available in versions specified over commercial,
industrial and military temperature ranges. It is offered in 8-pin
plastic mini-DIP, small outline (SOIC), hermetic cerdip and
hermetic TO-99 metal can packages. Chips, MIL-STD-883B,
Rev. C, and tape & reel parts are also available.
4. The AD707 can be used where chopper amplifiers are
required, but without the inherent noise and application
problems.
5. The AD707 is an improved pin-for-pin replacement for the
LT1001.
