The AD708 is a high precision, dual monolithic operational The AD708S is rated over the military temperature range of amplifier. Each amplifier individually offers excellent dc −55°C to +125°C and is available in a CERDIP military version precision with maximum offset voltage and offset voltage drift processed to MIL-STD-883B. of any dual bipolar op amp.
PRODUCT HIGHLIGHTS
The matching specifications are among the best available in any dual op amp. In addition, the AD708 provides 5 V/μV mini- 1. The combination of outstanding matching and individual mum open-loop gain and guaranteed maximum input voltage specifications make the AD708 ideal for constructing high noise of 350 nV p-p (0.1 Hz to 10 Hz). All dc specifications gain, precision instrumentation amplifiers. show excellent stability over temperature, with offset voltage 2. The low offset voltage drift and low noise of the AD708 drift typically 0.1 μV/°C and input bias current drift of allow the designer to amplify very small signals without 25 pA/°C maximum. sacrificing overall system performance. The AD708 is available in four performance grades. The 3. The AD708 10 V/μV typical open-loop gain and 140 dB AD708J is rated over the commercial temperature range of common-mode rejection make it ideal for precision 0°C to 70°C and is available in a narrow body, PDIP. The applications. AD708A and AD708B are rated over the industrial temperature range of −40°C to +85°C and are available in a CERDIP.
