Product Details
The AD8209A is a single-supply difference amplifier ideal for amplifying and low-pass filtering small differential voltages in the presence of a large common-mode voltage. The input common-mode voltage range extends from −2 V to +50 V at a single 5 V supply. The AD8209A is qualified per AEC-Q100 specifications. The amplifier offers enhanced input overvoltage and ESD protection, and includes electromagnetic interference (EMI) filtering.
Automotive applications demand robust, precision components for improved system control. The AD8209A provides excellent ac and dc performance, minimizing errors in the application. Typical offset and gain drift in the MSOP package are less than 5 μV/°C and −5 ppm/°C, respectively. The device also delivers a minimum common-mode rejection ratio (CMRR) of 80 dB from dc to 10 kHz.
The AD8209A features an externally accessible 100 kΩ resistor at the output of the preamplifier (A1) that can be used for low-pass filtering and for establishing gains other than 14 V/V.
Applications- High-side current sensing
- Motor controls
- Solenoid controls
