The AD8207 is a single-supply difference amplifier ideal for amplifying small differential voltages in the presence of large common-mode voltage. The operating input common-mode voltage range extends from −4 V to +65 V with a 5 V supply. The AD8207 works with a single-supply voltage of 3.3 V to 5 V, and is ideally suited to withstand large input PWM commonmo.
Ideal for current shunt applications EMI filters included 1 μV/°C maximum input offset drift High common-mode voltage range −4 V to +65 V operating (5 V supply) −4 V to +35 V operating (3.3 V supply) −25 V to +75 V survival Gain = 20 V/V 3.3 V to 5.5 V supply range Wide operating temperature range: −40°C to +125°C Bidirectional current monitoring <500 nV/°C typical offset drift <10 ppm/°C typical gain drift >90 dB CMRR dc to 10 kHz Qualified for automotive applications
