The MAX4081TASA+ is a high-side current sense amplifier designed for voltages up to 76V, suitable for applications requiring bidirectional current measurement. It features an 8-pin NSOIC package, providing a single voltage output that indicates current flow direction—monitoring charge and discharge without needing a separate polarity output. The device uses an external reference to set the zero-current level (VSENSE = 0V). The output voltage ranges from VREF to VCC during charging and from VREF to GND during discharging. It supports a wide input voltage range for both supply and input common-mode voltages, making it ideal for high-voltage systems where high side measurement is essential. The amplifier offers a gain of 20 V/V with ±0.1% accuracy at 25°C, a bandwidth of 150 kHz, and excellent common-mode rejection (124 dB). It features low input offset voltage (100 µV at 25°C) and low input bias current (5 µA at 76V). Operating over 4.5V to 76V supply voltage and temperatures from -40°C to 125°C, the device provides high accuracy with low quiescent current (103 µA), and its compact design minimizes board space requirements. It is well-suited for sensing and instrumentation, motor control, automotive applications, and power management systems.
