Linear Hall-Effect Sensor ICs with Analog Output

Available in a Miniature, Low-Profile Surface-Mount Package

FEATURES AND BENEFITS

DESCRIPTION

• 5 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 A1308 and A1309

linear Hall-effect sensor ICs have been designed specifically

to meet both requirements. These temperature-stable devices

areavailableinbothsurface-mountandthrough-holepackages.

• 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

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

optimization. Each device features nonvolatile 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 A1308 and A1309 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.

• Undervoltage lockout (UVLO)

• Wide ambient temperature range:

–40°C to 150°C (SOT-23W), –40°C to 125°C (SIP)

• Immune to mechanical stress

• 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. The

quiescent voltage output is adjusted around 50% of the supply

voltage.
