General Description
The MAX9643 is a high-speed 60V precision unidirec-
tional current-sense amplifier ideal for a wide variety of
power-supply control applications. Its high signal band-
width allows its use within DC-DC switching converter
power-supply control loops with minimal phase delay.
The IC also features 130FV (max) precision input offset
voltage, allowing small sense resistors to be used in
applications where efficiency is important and when wide
dynamic-range current measurement is needed.
High DC CMRR and AC CMRR make it easy to use in
a wide variety of aggressive environments. The device
is available in fixed gains of 2.5V/V and 10V/V. It is also
available in a small, 8-pin TDFN (2mm x 3mm) package
and is rated over the -40NC to +125NC temperature range.
