MAXIM INTEGRATED / ANALOG DEVICES MAX4378FASD High-Side Current Sense Amplifier
The MAX4378FASD+ is a quad precision high-side current sense amplifier housed in a 14-pin NSOIC package. It features an internal gain of 50 V/V and a buffered voltage output, eliminating the need for external gain setting resistors. The device is designed for applications requiring accurate current monitoring, such as in power supplies, fuel gauges, general system monitoring, and power amplifier bias control loops. It supports a wide supply voltage range from 3V to 28V and operates reliably across automotive temperatures from -40°C to 125°C. Each amplifier consumes approximately 1mA of supply current and offers a typical full-scale accuracy of ±0.5%. The input common mode range is from 2V to 28V, independently of the supply voltage, ensuring functional measurements even when connected to a deep discharge battery pack. Its adjustable sense resistor allows precise setting of full-scale current readings. The amplifier provides a buffered output with a drive capability of 2mA, bandwidth of 1.7MHz at 100mV sense voltage with a gain of +50V/V, and a slew rate of 10V/μs. Its high CMRR and PSRR of 90dB, along with low input bias current of 120μA at VRS+ ≤ 2V, enable accurate and stable performance in demanding environments.
