PGA450Q1EVM Datasheet PDF - TI

●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.

● Single power supply input for basic operation

● push pull transformer and 58KHz transducer

● LIN master transceiver

● RS232 transceiver for UART testing and debug

● PC control with a graphical user interface and USB communications board
