AD524: 仪表放大器
The AD524 is a precision monolithic instrumentation amplifier designed for data acquisition applications requiring high accuracy 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 uV/ °C, input offset voltage drift of less than 0.5 uV/°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 25MHz gain bandwidth product (G = 1000). To make it suitable for high speed data ac-quisition systems the AD524 has an output slew rate of 5 V/us and settles in 15us to 0.01% for gains of 1 to 100.
As a complete amplifier the AD524 does not require any external 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.
