PRODUCT DESCRIPTION

The AD708 is a very high precision, dual monolithic operational

amplifier. Each amplifier individually offers excellent dc precision

with the best available max offset voltage and offset voltage drift

of any dual bipolar op amp. In addition, the matching specifica-

tions are the best available in any dual op amp.

The AD708 sets a new standards for dual precision op amps by

providing 5 V/µV min open loop gain and guaranteed max input

voltage noise of 350 nV p-p (0.1 Hz to 10 Hz). All dc specifica-

tions show excellent stability over temperature, with offset

voltage drift typically 0.1 µV/°C and input bias current drift of

25 pA/°C max. Both CMRR (130 dB min) and PSRR (120 dB

min) are an order of magnitude improved over any available

single monolithic op amp except the AD707.

APPLICATION HIGHLIGHTS

1. The combination of outstanding matching and individual

specifications make the AD708 ideal for constructing high

gain, precision instrumentation amplifiers.

2. The low offset voltage drift and low noise of the AD708

allows the designer to amplify very small signals without

sacrificing overall system performance.

The AD708 is available in four performance grades. The

AD708J is rated over the commercial temperature range of 0°C

to +70°C and jis available in a plastic mini-DIP package. The

AD708A and AD708B are rated over the industrial temperature

range of –40°C to +85°C and are available in a cerdip and TO-

99 package. The AD708S is rated over the military temperature

range of –55°C to +125°C and is available in cerdip and TO-99

packages. Military versions are available processed to MIL-

STD-883B, Rev. C.

3. The AD708’s 10 V/µV typical open loop gain and 140 dB

common-mode rejection make it ideal for precision

applications.

4. Unmounted dice are available for hybrid circuit applications.

5. The AD708 is an improved replacement for the LT1002.
