Each amplifier individually offers excellent dc precision with maximum offset voltage and offset voltage drift of any dual bipolar op amp. The matching specifications are among the best available in any dual op amp. In addition, the AD708 provides 5 V/μV minimum open-loop gain and guaranteed maximum input voltage noise of 350 nV p-p (0.1 Hz to 10 Hz). All dc specifications show excellent stability over temperature, with offset voltage drift typically 0.1 μV/°C and input bias current drift of 25 pA/°C maximum. The AD708 is available in four performance grades. The AD708J is rated over the commercial temperature range of 0°C to 70°C and is available in a narrow body, PDIP. The AD708A and AD708B are rated over the industrial temperature range of −40°C to +85°C and are available in a CERDIP.
