CHOPPER-STABILIZED, PRECISION

HALL-EFFECT SWITCH

The A3240-- Hall-effect 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, tempera-

ture dependencies, and thermal stress.

Suffix ‘–LT’ & ‘–UA’ Pinning

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

PTCT

The 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. 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 modified

SOT23W surface-mount package, ‘–LT’ is a miniature SOT89/TO-

243AA transistor package for surface-mount applications; while suffix

‘–UA’ is a three-lead ultra-mini-SIP for through-hole mounting.

FEATURES

■ Resistant to Physical Stress

■ Superior Temperature Stability

■ Output Short-Circuit Protection

■ Operation From Unregulated Supply

■ Reverse Battery Protection

■ Solid-State Reliability

■ Small Size

Suffix ‘E–’.................. -40°C to +85°C

Suffix ‘L–’................ -40°C to +150°C

*Internal current limiting is intended to protect

the device from output short circuits.

Always order by complete part number: the prefix ‘A’ + the basic four-

digit part number + a suffix to indicate operating temperature range +

a suffix to indicate package style, e.g., A3240ELH .
