Description
The MAX9938 high-side current-sense amplifier offers
precision accuracy specifications of Vos less than 500μV
(max) and gain error less than 0.5% (max). Quiescent
supply current is an ultra-low 1μA. The MAX9938 fts
in a tiny, 1mm x 1mm UCSPTM 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 accuracy, low quiescent
current, and small size are critical.
The MAX9938 features an input common-mode voltage
range from 1.6V to 28V. These current-sense ampli-
fiers have a voltage output and are offered in four gain
versions: 25VN (MAX9938T), 50V/V (MAX9938F),
100VV (MAX9938H), and 200V/V (MAX9938W).
The four gain selections offer flexibility in the choice of
the external current-sense resistor. The very low 500μV
(max) input offset voltage allows small 25mV to 50mV
fll-scale VSENSE voltage for very low voltage drop at
full-current measurement.
The MAX9938 is offered in tiny 4-bump, UCSP (1mm x
1mm x 0.6mm footprint), 5-pin SOT23, and 6-pin μDFN
(2mm x 2mm x 0.8mm) packages specifed for operation
over the -40*C to +85°C extended temperature range.
