A1308 and A1309: Linear Hall-Effect Sensor ICs with
Analog Output Available in Miniature, Low-Profile Surface-
Mount and SIP Packages
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 are available in
both surface-mount and through-hole packages.
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.
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 they 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 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.
The A1308 and A1309 sensor ICs are offered in two package styles. The LH is a SOT-23W style, miniature,
low-profile package for surface-mount applications. The UA is a 3-pin, ultramini, single inline package (SIP)
for through-hole mounting. Both packages are lead (Pb) free, with 100% matte-tin leadframe plating.
