A17700 Pressure Sensor Interface ICs

Allegro MicroSystems A17700 Pressure Sensor Interface ICs are designed to interface a piezoresistive bridge for pressure sensing. The A17700 features high accuracy output in Analog, PWM, and SENT format with diagnostic. The device's accuracy is achieved by gain/offset input signal trim and 4th order polynomial input signal compensation at applied pressure and temperature. The 4th order polynomial compensation algorithm allows users to optimize accuracy versus test cost (chose # of test points) and is flexible enough for multiple applications.
