GENERAL 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 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,

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. The AD524 is

available in a 16-lead ceramic DIP, 16-lead SBDIP, 16-lead SOIC

wide packages, and 20-terminal leadless chip carrier.

The AD524 has guaranteed low offset voltage, offset

voltage drift, and low noise for precision high gain

applications.

The AD524 is functionally complete with pin program-

mable gains of 1, 10, 100, and 1000, and single resistor

programmable for any gain.

Input and output offset nulling terminals are provided for

very high precision applications and to minimize offset

voltage changes in gain ranging applications.

The AD524 is input protected for both power-on and

power-off fault conditions.

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 μs to 0.01% of a 20 V step

(G = 100).
