Part Overview
Description
The MAX9934 is a high-precision, low-voltage, high-side current-sense amplifier designed for bidirectional and unidirectional current measurements in battery-powered portable and laptop devices. It features a low input offset voltage of 10µV (max) and a wide input common-mode voltage range of -0.1V to 5.5V. The MAX9934's precision input specification allows for the use of small sense voltages (typically 10mV full-scale) for minimally invasive current sensing.
The output of the MAX9934 is a current proportional to the input VSENSE and is available in either 25μA/mV or 5μA/mV gain options (GM) with gain accuracy better than 0.25% (max) at 25°C. A chip select (CS) allows multiplexing of several MAX9934 current outputs to a single microcontroller ADC channel. The CS is compatible with 1.8V and 3.3V logic systems.
The MAX9934 operates from a 2.5V to 3.6V VCC supply and draws just 120uA (typ) quiescent current. When powered down (Vcc = 0), RS and RS- draw less than 0.1nA (typ) leakage current to reduce battery load. The MAX9934 is robust and protected from input faults of up to 16V input differential voltage between RS and RS-.
