19-5011; Rev 0; 10/09 KIT ATION EVALU LE B A IL A AV 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.
