GENERAL DESCRIPTION
The AD708 is a high precision, dual monolithic operational
amplifier. 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 mini-
mum 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.
The AD708S is rated over the military temperature range of
−55°C to +125°C and is available in a CERDIP military version
processed to MIL-STD-883B.
PRODUCT HIGHLIGHTS
1.
The combination of outstanding matching and individual
specifications make the AD708 ideal for constructing high
gain, precision instrumentation amplifiers.
The low offset voltage drift and low noise of the AD708
allow the designer to amplify very small signals without
sacrificing overall system performance.
The AD708 10 V/μV typical open-loop gain and 140 dB
common-mode rejection make it ideal for precision
applications.
