A3240

Chopper-Stabilized, Precision

Hall-Effect Switch

Features and Benefits

▪ Resistant to Physical Stress

▪ Superior Temperature Stability

▪ Output Short-Circuit Protection

▪ Operation From Unregulated Supply

▪ Reverse Battery Protection

▪ Solid-State Reliability

Description

The A3240 Hall-effect switch is an extremely tempera-

ture-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

residualoffsetvoltagenormallycausedbydeviceovermolding,

temperature dependencies, and thermal stress.

▪ Small Size

Thedeviceincludesonasinglesiliconchipavoltageregulator,

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

permits operation with supply voltages of 4.2 to 24 volts.
