A1324, A1325, A1326: Low Noise, Linear Hall Effect Sensor ICs with Analog Output

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 A1324, 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 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.
