A1318 and A1319

Linear Hall-Effect Sensor ICs with Analog Output

Available in a Miniature, Low Profile Surface Mount Package

Features and Benefits

Description

• 3.3 V supply operation

New applications for linear output Hall-effect sensors, such

as displacement and angular position, require higher accuracy

and smaller package sizes. The Allegro A1318 and A1319

linearHall-effectsensorICshavebeendesignedspecificallyto

meet both requirements. These temperature-stable devices are

available in both surface-mount and through hole packages.

• QVO temperature coefficient programmed at Allegro^™for

improved accuracy

• Miniature package options

• High bandwidth, low noise analog output

• High speed chopping scheme minimizes QVO drift across

operating temperature range

• Temperature-stable quiescent voltage output and sensitivity

• Precise recoverability after temperature cycling

• Output voltage clamps provide short circuit diagnostic

capabilities

• Undervoltage lockout (UVLO)

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

• Immune to mechanical stress

• Enhanced EMC performance for stringent automotive

applications

The accuracy of each device is enhanced via end-of-line

optimization. Each device features non-volatile memory to

optimize device sensitivity and the quiescent voltage output

(QVO: output in the absence of a magnetic field) for a given

application or circuit. This A1318 and A1319 optimized

performance is sustained across the full operating temperature

range by programming the temperature coefficient for both

sensitivity and QVO at Allegro end-of-line test.

These ratiometric Hall-effect sensor ICs provide a voltage

output that is proportional to the applied magnetic field. The

quiescent voltage output is adjusted around 50% of the supply

voltage.

The features of these linear devices make them ideal for

use in automotive and industrial applications requiring high

accuracy, and operate across an extended temperature range,

–40°C to 150°C.

Each BiCMOS monolithic circuit integrates a Hall element,

temperature-compensating circuitry to reduce the intrinsic
