The AD8213 is a dual-channel, precision current sense amplifier.
It features a set gain of 20 V/V, with a maximum ±0.5% gain
error over the entire temperature range. The buffered output
voltage directly interfaces with any typical converter. Excellent
common-mode rejection from −2 V to +65 V, is independent of
the 5 V supply. The AD8213 performs unidirectional current
measurements across a shunt resistor in a variety of industrial
and automotive applications, such as motor control, solenoid
control, or battery management.

Special circuitry is devoted to output linearity being maintained
throughout the input differential voltage range of 0 mV to 250 mV,
regardless of the common-mode voltage present. The AD8213
also features additional pins that allow the user to low-pass filter
the input signal before amplifying, via an external capacitor to
ground. The AD8213 has an operating temperature range of −40°C
to +125°C for the Y grade, −40°C to +150°C for the H grade and is
offered in a small 10-lead MSOP package.
