MAXIM INTEGRATED / ANALOG DEVICES MAX9934FAUA Current-Sense Amplifier
The MAX9934FAUA+ is a high-precision, low-voltage current-sense amplifier designed for accurate current measurement in portable and laptop devices. It features an input voltage range of -0.1V to +5.5V, a low offset voltage of 10µV, and operates from a supply voltage of 2.5V to 3.6V. The amplifier provides a current output with a gain of 5µA/mV, offering high accuracy with a gain error of less than 0.25% at 25°C. It supports bidirectional and unidirectional current sensing with minimal intrusion, using small sense voltages typically around ±10mV full-scale. The device includes a chip select input compatible with 1.8V and 3.3V logic systems for multiplexing multiple channels to a single ADC input. When powered down, it draws less than 0.1nA leakage current to conserve battery life. The MAX9934 is protected against input differential voltages up to ±6V and features flexible output routing for gain adjustments. Its typical quiescent current is 120µA. Suitable for signal processing and portable applications, this amplifier ensures robust performance in demanding environments.
