MAXIM INTEGRATED / ANALOG DEVICES MAX4378FAUD High-Side Current Sense Amplifier
The MAX4378FAUD+ is a quad precision high-side current sense amplifier housed in a 14-pin TSSOP package. It features an internal gain of 50 V/V and buffered voltage output that eliminates the need for gain-setting resistors, making it ideal for accurate current monitoring applications. This device supports a wide input common mode voltage range of 0 to 28 V, independent of the supply voltage, ensuring reliable current sensing even in battery packs with deep discharge. It is suitable for use in current-limited power supplies, fuel gauge systems in personal computers, general system and board-level current monitoring, and power amplifier bias control. The amplifier operates with a supply voltage range from 3 V to 28 V, has an automotive temperature range from -40°C to 125°C, and consumes only 1 mA per amplifier. It offers high accuracy with typical full-scale accuracy of ±0.5%, an adjustable sensing capability using an external sense resistor, and buffered output with a 2 mA drive capacity. The bandwidth reaches 1.7 MHz with a slew rate of 10 V/µs, and it boasts high CMRR and PSRR of 90 dB each. Critical input bias current is only 120 µA at a sense voltage of 150 mV within a common mode range of 2 V to 28 V, functioning reliably down to 0 V.
