The A1342 device is a high-precision, programmable Hall-effect linear sensor integrated circuit (IC) with an open-drain output, for both automotive and nonautomotive applications. The signal path of the A1342 provides flexibility through external programming that allows the generation of an accurate, and customized, output from an input magnetic signal.
The A1342 is an especially configurable and robust solution for the most demanding linear field sensor applications. The BiCMOS, monolithic IC incorporates a Hall sensing element, precision temperature-compensating circuitry to reduce the intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, proprietary dynamic offset cancellation circuits, advanced output linearization circuitry, and advanced diagnostics. The A1342 provides an unmatched level of customer-programmable options.
