Ratiometric Linear Hall Effect Sensor

for High-Temperature Operation

Features and Benefits

▪ Temperature-stable quiescent output voltage

▪ Precise recoverability after temperature cycling

Description

TheA132X family of linear Hall-effect sensors are optimized,

sensitive,andtemperature-stable.TheseratiometricHall-effect

▪ Output voltage proportional to magnetic flux density

▪ Ratiometric rail-to-rail output

▪ Improved sensitivity

▪ 4.5 to 5.5 V operation

▪ Immunity to mechanical stress

▪ Solid-state reliability

sensors provide a voltage output that is proportional to the

applied magnetic field. The A132X family has a quiescent

output voltage that is 50% of the supply voltage and output

sensitivity options of 2.5mV/G, 3.125mV/G, and 5mV/G. The

features of this family of devices are ideal for use in the harsh

environments found in automotive and industrial linear and

rotary position sensing systems.

▪ Robust EMC protection

EachdevicehasaBiCMOSmonolithiccircuitwhichintegrates

a Hall element, improved temperature-compensating circuitry

to reduce the intrinsic sensitivity drift of the Hall element,

a small-signal high-gain amplifier, and a rail-to-rail low-

impedance output stage.

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)

A proprietary dynamic offset cancellation technique, with

an internal high-frequency clock, reduces the residual offset

voltage normally caused by device overmolding, temperature

dependencies, and thermal stress. The high frequency clock

allows for a greater sampling rate, which results in higher

accuracyandfastersignalprocessingcapability.Thistechnique
