Overview: 3260
Suffix Code 'LH' Pinning 2-WIRE, CHOPPER-STABILIZED, PRECISION HALL-EFFECT BIPOLAR SWITCH
The A3260-- Hall-effect bipolar switch is an extremely 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 optimized package for most applications. Suffix ‘–LH’ is a miniature lowprofile surface-mount package, ‘–LT’ is a miniature SOT-89/TO243AA transistor package for surface-mount applications; while suffix ‘–UA’ is a three-lead ultra-mini-SIP for through-hole mounting.
