1µA, 4-Bump UCSP/SOT23,

Precision Current-Sense Amplifier

MAX938

General Description

Features

The MAX9938 high-side current-sense amplifier offers

o Ultra-Low Supply Current of 1µA (max)

precision accuracy specifications of V

less than

o Low 500µV (max) Input Offset Voltage

o Low < 0.5% (max) Gain Error

o Input Common Mode: +1.6V to +28V

o Voltage Output

500μV (max) and gain error less than 0.5% (max).

Quiescent supply current is an ultra-low 1μA. The

MAX9938 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.

o Three Gain Versions Available

25V/V (MAX9938T)

50V/V (MAX9938F)

100V/V (MAX9938H)

The MAX9938 features an input common-mode voltage

range from 1.6V to 28V. These current-sense amplifiers

have a voltage output and are offered in three gain ver-

sions: 25V/V (MAX9938T), 50V/V (MAX9938F), and

100V/V (MAX9938H).

o Tiny 1mm x 1mm x 0.6mm, 4-Bump UCSP

or 5-Pin SOT23 Package

The three 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
