CHOPPER-STABILIZED, PRECISION

HALL-EFFECT LATCHES

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

temperature-stable and stress-resistant sensors especially suited for op-

eration over extended temperature ranges to +150°C. Superior high-tem-

perature performance is made possible through dynamic offset cancella-

tion, 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

(SOT89/TO-243AA & ultra-mini SIP)

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 regula-

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

Three package styles provide a magnetically optimized package for

most applications. Package type LH is a modified SOT23W surface-

mount package, LT is a miniature SOT89/TO-243AA transistor package

for surface-mount applications; while UA is a three-lead ultra-mini-SIP

for through-hole mounting. Each package type is also available in a lead

(Pb) free version (suffix, –T) , with a 100% matte tin plated leadframe.
