High-Precision Nanopower 1D Linear Hall-Effect Sensor with Integrated Enable

A31015

The A31015 is a ratiometric linear Hall-effect sensor engineered to extend battery life in space-constrained portable applications through industry-leading power management. By utilizing a dedicated active-high enable (EN) pin, engineers can duty-cycle the device to achieve an average power consumption of less than 1 µW (at 10 Hz), while an ultra-low leakage sleep mode (< 1 nA) ensures minimal drain during inactivity. With a fast 13 µs wake-up time and high-impedance output in sleep mode, the A31015 allows for seamless integration into multiplexed sensor arrays or shared ADC lines without compromising system precision or thermal budgets.
