PRODUCT DESCRIPTION
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
V/
°C, input offset voltage drift of less than 0.5 V/°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 MHz gain bandwidth
product (G = 100). To make it suitable for high speed data ac-
quisition systems the AD524 has an output slew rate of 5 V/
s
and settles in 15
s 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 1,000. 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, higher linearity “C” grade are specified from –25
°C to
+85
°C. The “S” grade guarantees performance to specification
over the extended temperature range –55
°C to +125°C. Devices
are available in 16-pin ceramic DIP and SOIC packages and a
20-terminal leadless chip carrier.

PRODUCT HIGHLIGHTS
1. The AD524 has guaranteed low offset voltage, offset voltage
drift and low noise for precision high gain applications.
2. The AD524 is functionally complete with pin programmable
gains of 1, 10, 100 and 1000, and single resistor program-
mable for any gain.
3. Input and output offset nulling terminals are provided for
very high precision applications and to minimize offset volt-
age changes in gain ranging applications.
4. The AD524 is input protected for both power on and power
off fault conditions.
5. The AD524 offers superior dynamic performance with a gain
bandwidth product of 25 MHz, full power response of 75 kHz
and a settling time of 15
s to 0.01% of a 20 V step (G = 100).
