The AD5243BRMZ10-RL7 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 AD5243BRMZ10-RL7 suitable for use in many data acquisition systems.
The AD5243BRMZ10-RL7 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 AD5243BRMZ10-RL7 also has a 25MHz gain bandwidth product (G = 1000). To make it suitable for high speed data ac-quisition systems the AD5243BRMZ10-RL7 has an output slew rate of 5 V/µs and settles in 15µs to 0.01% for gains of 1 to 100.
As a complete amplifier the AD5243BRMZ10-RL7 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 AD5243BRMZ10-RL7 input is fully protected for both power on and power off fault conditions.
The AD5243BRMZ10-RL7 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.
