The AD524 is a precision monolithic instrumentation amplifier
designed for data acquisition applications requiring high accu-
racy under worst-case operating conditions. An outstanding
combination of high linearity, high common-mode rejection,
low offset voltage drift, and low noise makes the AD524 suitable
for use in many data acquisition systems.
The AD524 has an output offset voltage drift of less than 25 μV/°C, input offset voltage drift of less than 0.5 μV/°C, CMR
above 90 dB at unity gain (120 dB at G = 1000), and maximum
nonlinearity of 0.003% at G = 1. In addition to the outstanding dc specifications, the AD524 also has a 25 kHz bandwidth
(G = 1000). To make it suitable for high speed data acquisition
systems, the AD524 has an output slew rate of 5 V/μs and settles
in 15 μs to 0.01% for gains of 1 to 100.
As a complete amplifier, the AD524 does not require any exter-
nal components for fixed gains of 1, 10, 100 and 1000. For other
gain settings between 1 and 1000, only a single resistor is required. The AD524 input is fully protected for both power-on and
power-off fault conditions.
The AD524 IC instrumentation amplifier is available in four
different versions of accuracy and operating temperature range.
The economical A grade, the low drift B grade, and lower drift,
