Description
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
sensor ICs are designed specifically to achieve both goals. This
temperature-stable device is available in a miniature surface
mount package (SOT23W) and an ultra-mini through-hole
single in-line package.
These ratiometric Hall effect sensor ICs provide a voltage
output that is proportional to the applied magnetic field. They
feature a quiescent voltage output of 50% of the supply voltage.
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
automotive and industrial applications requiring high accuracy,
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), and a 3-pin surface mount SOT-23 style package (LH). Both
are lead (Pb) free, with 100% matte tin leadframe plating.
