PGA450Q1EVM

The PGA450Q1EVM is an evaluation board for PGA450-Q, an interface device for ultrasonic transducers used in automotive parking assistance and blind spot detection applications. The device functions as the driver and receiver for a wide range of transducers with frequency ranges from 40kHz to 70kHz. The PGA450-Q1 incorporates an analog front end (AFE) and a 8051 microprocessor core. The AFE includes voltage regulators, an amplifier, an ADC, an oscillator, and a temperature sensor. The PGA450-Q1 also implements LIN 2.1 physical layer for communication.
