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 commonmode voltages, typical in solenoid and motor control applications. The AD8207 is available in an 8-lead SOIC package. Excellent dc performance over temperature keeps errors in the measurement loop to a minimum. Offset drift is typically less than 500 nV/C, and gain drift is typically below 10 ppm/C.
