The AD8202-KGD is a single-supply difference amplifier ideal for amplifying and low-pass filtering small differential voltages in high-side current sensing, motor controls, solenoid controls, power management, low-side current sensing and diagnostic protection applications.
The AD8202-KGD is a single-supply difference amplifier designed to amplify and low-pass filter small differential voltages in the presence of large common-mode voltages. It is a Known Good Die (KGD) fully guaranteed to data sheet specifications and is qualified for automotive applications, providing robust precision components for improved system control.
The device features an input common-mode voltage range extending from -8 V to +28 V when operating at a single +5 V supply. It offers excellent AC and DC performance, including a minimum CMRR of 80 dB from DC to 10 kHz, low voltage offset, and low gain drift. The AD8202-KGD includes an externally accessible 100 kΩ resistor at the output of the preamplifier, which can be used for low-pass filtering and establishing gains other than 20.
