2-WIRE, CHOPPER-STABILIZED,

PRECISION HALL-EFFECT BIPOLAR SWITCH

The A3260-- Hall-effect bipolar switch is an extremely

Suffix Code 'LH' Pinning

temperature-stable and stress-resistant sensor 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 device includes on a single silicon chip a voltage regulator,

Hall-voltage generator, small-signal amplifier, chopper stabilization,

Schmitt trigger, and a constant-current open-collector output. A south

pole of sufficient strength will turn the output OFF. An on-board

regulator permits operation with supply voltages of 3.5 to 24 volts.

Noise radiation is limited by control of the output current slew rate.

The first character of the part number suffix determines the device

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

-40°C to +150°C. Three package styles provide a magnetically opti-

mized 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.
