A1220, A1221, A1222, and A1223
Chopper Stabilized Precision Hall Effect Latches
Features and Benefits Description
▪ Symmetrical latch switchpoints The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs
▪ Resistant to physical stress are extremely temperature-stable and stress-resistant devices
▪ Superior temperature stability especially suited for operation over extended temperature ranges
▪ Output short-circuit protection to 150°C. Superior high-temperature performance is made
▪ Operation from unregulated supply down to 3 V possible through dynamic offset cancellation, which reduces the
▪ Reverse battery protection residual offset voltage normally caused by device overmolding,
▪ Solid-state reliability temperature dependencies, and thermal stress. Each device
▪ Small package sizes includes on a single silicon chip a voltage regulator, Hall-
voltage generator, small-signal amplifier, chopper stabilization,
Schmitt trigger, and a short-circuit protected open-drain output
to sink up to 25 mA. A south pole of sufficient streng
