A1220 Datasheet Chopper-stabilized Precision Hall-effect Latches

Manufacturer: Allegro MicroSystems

Overview: A1220, A1221, A1222, and A1223 Chopper-Stabilized Precision Hall-Effect.

General Description

The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended temperature ranges to 150°C.

Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.

Each device includes on a single silicon chip a voltage regulator, Hallvoltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output to sink up to 25 mA.
