The AD8218 is Analog Devices’ new zero-drift, bidirectional current-sense amplifier. It features a zero-drift core that provides an offset drift of +100 nV/°C over a -40°C to
+125°C temperature range, while maintaining a typical small signal bandwidth of 500 kHz. The device has a 20 V/V fixed gain with a maximum ±0,35% gain error over the entire temperature range. Its input common-mode can vary from 4 V to 80 V and includes a built-in reference for optimal dynamic range in unidirectional current monitoring or the ability to offset the output for bidirectional current sensing. Designed to operate with a wide variety of A/D converters, the AD8218 is suitable for numerous high-side current-sensing signal chains, including base station, industrial motor control and computer power management applications.
