The AD708 is a high precision, dual monolithic operational amplifier. Each amplifier individually offers excellent dc precision with maximum offset voltage drift of any dual bipolar op-amp.
The matching specification are among the best available in any dual op-amp. In addition, the AD708 provides 5V/µV minimum open-loop gain and guaranteed maximum input voltage noise of 350nV p-p (0.1Hz to 10Hz). All DC specifications show excellent stability over temperature, with offset voltage drift typically 0.1µV/°C and the input bias current drift of 25pA/°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. The AD708S is rated the military temperature range of -55°C to +125°C and is available in the CERDIP military version processed to MIL-STD-883B.
