AND 3283

CHOPPER-STABILIZED, PRECISION

HALL-EFFECT LATCHES

The A3280--, A3281--, and A3283-- Hall-effect latches are ex-

tremely temperature-stable and stress-resistant sensors 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.

Suffix '–LT' & '–UA' Pinning

PTCT

Each device 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-collector output to

sink up to 25 mA. A south pole of sufficient strength will turn the

output on. A north pole is necessary to turn the output off. An on-board

regulator permits operation with supply voltages of 4.2 to 24 volts.

The first character of the part number suffix determines the device

operating temperature range; suffix ‘E–’ is for -40°C to +85°C and

‘L–’ is -40°C to +150°C. Three package styles provide a magnetically

optimized package for most applications. Suffix ‘–LH’ is a miniature

low-profile surface-mount package, ‘–LT’ is a miniature SOT-89/TO-

243AA transistor package for surface-mount applications; while suffix

‘–UA’ is a three-lead ultra-mini-SIP for through-hole mounting.
