GENERAL DESCRIPTION

The AD8216 is a single-supply, difference amplifier ideal for

amplifying small differential voltages in the presence of large

common-mode voltages. The operating input common-mode

voltage range extends from −4 V to +65 V. The typical supply

voltage is 5 V. The AD8216 features a 3 MHz bandwidth,

allowing for the input-to-output propagation delay that is

always less than 150 ns. This feature is ideal for applications

monitoring rapidly increasing and decreasing load currents.

The AD8216 is offered in a SOIC package. The operating

temperature range is −40°C to +125°C.

Excellent ac and dc performance over temperature keep errors

in the measurement loop to a minimum. Offset and gain drift

are guaranteed to a maximum of 20 μV/°C and 15 ppm/°C,

respectively.

The output offset can be adjusted from 0.06 V to 4.9 V with a

output to be unipolar, starting near V+. Other offsets can be
