Zero drift current-sense amplifier offers high bandwidth performance
Using a proprietary CMOS process, the AD8218 features a zero-drift core that provides an offset drift of + 100n V/°C over a −40 °C to +125 °C temperature range, while maintaining a typical small signal bandwidth of 500 kHz.
ADI’s newest zero-drift current-sense amplifier has a 20 V/V fixed gain with a maximum ±0.35 percent gain error over the entire temperature range. The AD8218 zero-drift precision amplifier’s 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 easily offset the output for bidirectional current sensing.
