The AD524 is a precision monolithic instrumentation amplifier
PRODUCT HIGHLIGHTS
designed for data acquisition applications requiring high accu- 1. Guaranteed low offset voltage, low offset voltage drift, and racy under worst-case operating conditions. An outstanding low noise for precision high gain applications. combination of high linearity, high common-mode rejection, 2. Functionally complete with pin programmable gains of 1, low offset voltage drift, and low noise makes the AD524 suitable 10, 100, and 1000, and single resistor-programmable for for use in many data acquisition systems. The AD524 has an any gain. output offset voltage drift of less than 25 μV/°C, input offset 3. Input and output offset nulling terminals are provided for voltage drift of less than 0.5 μV/°C, CMR above 90 dB at unity high precision applications and to minimize offset voltage gain (120 dB at G = 1000), and maximum nonlinearity of changes in gain ranging applications. 0.003% at G = 1. The gain bandwidth product of the AD524 is 4. Input protected for both power-on and power-off fault 25 kHz (G = 1000). The output slew rate of 5 V/μs and settling conditions. time of 15 μs to 0.01% for gains of 1 to 100, makes it suitable for 5. Superior dynamic performance with a gain bandwidth high speed data acquisition systems. product of 25 MHz, full power response of 75 kHz and a As a complete amplifier, the AD524 does not require any external settling time of 15 μs to 0.01% of a 20 V step (G = 100). 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 is available in four 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.
