GENERAL DESCRIPTION
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 common-
mode 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 mea-
surement loop to a minimum. Offset drift is typically less
than 500 nV/°C, and gain drift is typically below 10 ppm/°C.
The AD8207 is ideal for bidirectional current sensing
applications. It features two reference pins,VREF1 and VREF2,
that allow the user to easily offset the output of the device to
any voltage within the supply range. With VREF1 attached to the
V+ pin and VREF2 attached to the GND pin, the output is set at
half scale. Attaching both pins to GND causes the output to
be unipolar, starting near ground. Attaching both pins to V+
causes the output to be unipolar starting near V+. Other output
offsets are achieved by applying an external low impedance
voltage to the VREF1 and VREF2 pins.
