Features
- of this family of devices are ideal for use in the harsh environments found in automotive and industrial linear and rotary position sensing systems. Each device has a BiCMOS monolithic circuit which integrates a Hall element, improved temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, and a rail-to-rail lowimpedance output stage. A proprietary dynamic offset cancellation technique, with an internal high-frequency c.
