A3280

A3280, A3281, and A3283 Chopper-Stabilized, Precision Hall-Effect Latches Features and Benefits ▪ Symmetrical switch points ▪ Resistant to physical stress ▪ Superior temperature stability ▪ Output short-circuit protection ▪ Operation from unregulated supply ▪ Reverse battery protection ▪ Solid-state reliability ▪ Small size Packages: Package LH Package LT Not to scale Package UA Description The A3280, A3281, and A3283 Hall-effect latches are extremely temperature-stable and stress-resistant sensor ICs 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. The three devices are identical except for magnetic switch points. Each device includes on a single silicon chip a voltage regulator, Hall-voltage generator, small-signal amplif...
