High-Precision, Low-Voltage, Current-Sense Amplifier

with Current Output and Chip Select for Multiplexing

MAX934

General Description

Features

The MAX9934** high-precision, low-voltage, high-side

current-sense amplifier is ideal for both bidirectional

(charge/discharge) and unidirectional current measure-

ments in battery-powered portable and laptop devices.

o Input Offset Voltage: 10µV (max)

o Gain Error Less than 0.25%

o -0.1V to +5.5V Input Common-Mode Voltage

Range

Input offset voltage (V ) is a low 10µV (max) at +25°C

across the -0.1V to 5.5V input common-mode voltage

o Chip Select Allows Multiplexing Several MAX9934

range, and is independent of V . Its precision input

Current Monitors to One ADC

specification allows the use of very small sense volt-

ages (typically 10mV full-scale) for minimally invasive

current sensing.

o Current Output Allows R

Selection

OUT

for Gain Flexibility

o Single Supply Operation: 2.5V to 3.6V

The output of the MAX9934 is a current proportional to

input V

and is available in either 25µA/mV or

o Two Gain Options: G of 25µA/mV (MAX9934T)

SENSE

5µA/mV gain options (G ) with gain accuracy better

and 5µA/mV (MAX9934F)

than 0.25% (max) at +25°C. A chip select (CS) allows

multiplexing of several MAX9934 current outputs to a

single microcontroller ADC channel (see the Typical

Operating Circuit). CS is compatible with 1.8V and 3.3V

logic systems.

o Bidirectional or Unidirectional Operation

o Small, 6-Bump UCSP (1mm x 1.5mm x 0.6mm),

6-Pin µDFN (2mm x 2mm x 0.6mm), and 8-Pin

µMAX Packages

Ordering Information

The MAX9934 is designed to operate from a 2.5V to

3.6V V

supply, and draws just 120µA (typ) quiescent
