MAX9634
The MAX9634 high-side current-sense amplifier offers
precision accuracy specifications of V
OS
less than
250µV (max) and gain error less than 0.5% (max).
Quiescent supply current is an ultra-low 1µA. The
MAX9634 fits in a tiny, 1mm x 1mm UCSP™ package
size or a 5-pin SOT23 package, making the part ideal for
applications in notebook computers, cell phones, PDAs,
and all battery-operated portable devices where accura-
cy, low quiescent current, and small size are critical.
The MAX9634 features an input common-mode voltage
range from 1.6V to 28V. These current-sense amplifiers
have a voltage output and are offered in four gain versions:
25V/V (MAX9634T), 50V/V (MAX9634F), 100V/V
(MAX9634H), and 200V/V (MAX9634W).
The four gain selections offer flexibility in the choice of
the external current-sense resistor. The very low 250µV
(max) input offset voltage allows small 25mV to 50mV
full-scale V
SENSE
voltage for very low voltage drop at
full-current measurement.
The MAX9634 is offered in tiny 4-bump UCSP (1mm x
1mm x 0.6mm footprint) and 5-pin SOT23 packages
specified for operation over the -40°C to +85°C extend-
ed temperature range.
