The Analog Devices AD521KD is a second-generation, low-cost monolithic IC instrumentation amplifier. It functions as a gain block with differential inputs and an accurately programmable input/output gain relationship. The AD521KD requires only two resistors to set its gain to any value between 0.1 and 1000. Its high input impedance is 30 GΩ, and it boasts a high Common Mode Rejection Ratio (CMRR) of 110 dB minimum.
This instrumentation amplifier is designed for precision applications, offering a low offset voltage drift of 2 µV/°C (L grade) and low noise of 0.5 µV p-p (0.1Hz to 10Hz, RTI, Gain=1000). The inputs are protected against overvoltages up to ±15V beyond the supplies and 30V differential.
The AD521KD has a gain bandwidth product of 40 MHz and an output current limit of 25 mA. It is internally compensated for stability. The device is suitable for applications requiring accurate signal acquisition in challenging environments.
