Allegro MicroSystems A1326
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.| Part No. | A1326 |

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™ 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.
