GENERAL DESCRIPTION
The AD8217 is a high voltage, high-resolution current shunt
amplifier. It features a set gain of 20 V/V, with a maximum
?.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癈 to +125癈 temperature range. It features a zero-drift
core, which leads to a typical offset drift of ?00 nV/癈
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 ?00 糣.
The AD8217 is offered in a 8-lead MSOP package and is
specified from 40癈 to +125癈.
