MAX40080 is a high-precision, fast-response, bi-directional current-sense amplifier with digital output and a very wide input common-mode range from -0.1V (ground sensing) to 36V. The device features an ultra-low 5µV input offset voltage and a very low 0.2% gain error. Low input offset voltage is especially important because it allows using a small sense resistor, thus saving power dissipation, but at same time not compromising the measurement accuracy. Device also features a programmable input sensing range between ±10mV and ±50mV (or programmable input gain between 125V/V and 25V/V) which is very useful to enhance accuracy at low current. Device includes an analogue-to-digital converter with programmable sample rate and 12bit resolution (13bit including sign bit for current measurement). It features a wake-up current threshold and auto-shutdown mode when I2C is inactive. These features are designed to minimize power consumption. Used in server backplanes, base-station PA control.
