Allegro MicroSystems, LLC Introduces New Programmable Linear Hall-Effect Sensor IC
2017-02-07 | ReturnThe A1377 is available in a through-hole, small form factor, single in-line package (SIP) and has a broad range of sensitivity and offset operating bandwidth. The accuracy and flexibility of this device is enhanced with user programmability, via the VCC and output pins, which allows the device to be optimized in the application.
This ratiometric Hall-effect sensor IC provides a voltage output that is proportional to the applied magnetic field. The quiescent voltage output (QVO) is user-adjustable from approximately 5% to 95% of the supply voltage. The device sensitivity is adjustable within the range of 1 to 14 mV/G.
The features of this linear device make it ideal for use in automotive and industrial applications requiring high accuracy, and apply across an extended temperature range, from –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 A1377 sensor is provided in a 3-pin single in-line package (UC suffix) with bypass capacitors integrated into the package. It is lead (PB) free, with 100% matte-tin leadframe plating.
