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.
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.
