Additional Details

The AD8217 is a high voltage, high-resolution current shunt amplifier. It features a set gain of 20 V/V, with a maximum ±0.35% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8217 offers excellent common-mode rejection from 4.5 V to 80 V, and includes an internal LDO, which directly powers the device from the high voltage rail. Therefore, no addi-tional supply is necessary, provided that the input common-mode range is 4.5 V to 80 V. The AD8217 performs unidirectional current measurements across a shunt resistor in a variety of industrial and telecom applications including motor control, battery management, and base station power amplifier bias control.

The AD8217 offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zero-drift core, which leads to a typical offset drift of ±100 nV/°C throughout the operating temperature and common-mode voltage range. Special attention 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, and the typical input offset voltage is ±100 μV. The AD8217 is offered in a 8-lead MSOP package and is specified from −40°C to +125°C.

Applications

High side current sensing 48 V telecom Power management Base stations Unidirectional motor control Precision high voltage current sources
