Description
The A139x family of linear Hall-effect sensor integrated circuits (ICs) provide a voltage output that is directly proportional to an applied magnetic field.
Features
- ▪ High-impedance output during sleep mode ▪ Compatible with 2.5 to 3.5 V power supplies ▪ 10 mW power consumption in the active mode ▪ Miniature MLP/DFN package ▪ Ratiometric output scales with the ratiometric supply
reference voltage (VREF pin) ▪ Temperature-stable quiescent output voltage and
sensitivity ▪ Wide ambient temperature range:.
- 20°C to 85°C ▪ ESD protection greater than 3 kV ▪ Solid-state reliability ▪ Preset sensitivity and offset at final test.
