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  
OS  
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  
CC  
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)

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

The MAX9934 is specified for operation over the -40°C  
to +125°C temperature range and is available in 8-pin  
µMAX®, 6-pin µDFN (2mm x 2mm x 0.8mm), or a 6-  
bump UCSP™ (1mm x 1.5mm x 0.6mm), making it ideal  
for space-sensitive applications.
