High-Precision, Low-
Voltage, Current-Sense Amplifier with Current Output and Chip Select for Multiplexing
General Description
The MAX9934** high-precision, low-
voltage, high-side current-sense amplifier is ideal for both bidirectional (charge/discharge) and unidirectional current measurements in battery-powered portable and laptop devices.
Input offset
voltage (VOS) is a low 10µV (max) at +25°C across the -0.
1V to 5.
5V input common-mode
voltage range, and is independent of VCC.
Its precision input specification allows the use of very small sense
voltages (typically ±10mV full-scale) for minimally invasive current sensing.
