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 AllegroA1324, A1325, and A1326 linear Hall-effect
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 operate 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.
