A1324, A1325, and A1326

Low Noise, Linear Hall Effect Sensor ICs with Analog Output

Description

Features and Benefits

New applications for linear output Hall-effect devices, such

as displacement, angular position, and current measurement,

require high accuracy in conjunction with small package size.

The Allegro^®A1324, A1325, and A1326 linear Hall-effect

sensorICsaredesignedspecificallytoachievebothgoals.This

temperature-stable device is available in a miniature surface

mount package (SOT23W) and an ultra-mini through-hole

single in-line package.

• Temperature-stable quiescent output voltage and sensitivity

• Output voltage proportional to magnetic flux density

• Low-noise output increases accuracy

• Precise recoverability after temperature cycling

• Ratiometric rail-to-rail output

• Wide ambient temperature range: –40°C to 150°C

• Immune to mechanical stress

• Solid-state reliability

• Enhanced EMC performance for stringent automotive

applications

These ratiometric Hall effect sensor ICs provide a voltage

output that is proportional to the applied magnetic field. They

The A1324/25/26 feature factory programmed sensitivities of

5.0 mV/G, 3.125 mV/G, and 2.5 mV/G, respectively.

The features of these linear devices make them ideal for use in

automotiveandindustrialapplicationsrequiringhighaccuracy,

and are guaranteed through an extended temperature range,

–40°C to 150°C.

Each BiCMOS monolithic circuit integrates a Hall element,

temperature-compensating circuitry to reduce the intrinsic

sensitivity drift of the Hall element, a small-signal high-gain

amplifier, a clamped low-impedance output stage, and a

proprietary dynamic offset cancellation technique.

These devices are available in a 3-pin ultra-mini SIP package

(UA),anda3-pinsurfacemountSOT-23stylepackage(LH).Both

are lead (Pb) free, with 100% matte tin leadframe plating.
