Overview

This reference design is a small-form factor solution showcasing double-sided PCB spacing and minimum supporting component requirements for the PGA460 ultrasonic sensor signal conditioner. This module operates in a mono-static mode for single sensor transmit and receive operation to enable object detection through air at a range of 0.3 to 5m. Regardless of ambient temperature, humidity, and target color/transparency, object detection remains unaffected; however, maximum range can be hindered by very small or soft targets. The PGA460 operates exclusively as a slave device, and requires a separate master controller. TI recommends using the MSPEXP430F5529LP as an example master controller to repurpose the existing PGA460Q1EVM GUI and example source code.

Features
  • Integrated driver and receiver solution for ultrasonic sensing
  • Compatible with ultrasonic transducers operating at a center frequency between 30-80kHz and 180-480kHz
  • Able to generate maximum sound pressure level using a transformer driver
  • Access to all communication interfaces offered by the PGA460-Q1, including: USART (UART and SPI), TCI, and One-Wire UART
  • Record time for object detection up to 11-m in air
