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/
μ
V 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
μ
V/
°
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.
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.
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.
3. The AD708’s 10 V/
μ
V 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.
