PGA460-Q1 Ultrasonic Signal Conditioner EVM With
The PGA460-Q1 EVM evaluation module (EVM) allows users to evaluate the functionality of Texas
Instrument's PGA460-Q1 ultrasonic sensor-signal conditioner IC. The PGA460-Q1 is a fully integrated
system-on-chip, analog front-end (AFE) device for ultrasonic sensing. This user's guide describes both the
hardware platform containing a sample PGA460-Q1 device and the graphical user interface (GUI)
software used to configure the functionality and diagnostics. In addition to evaluating the PGA460-Q1
device, the other objective of this board is to display the ultrasonic echo profile and measurement results
of either a transformer driven closed-top transducer or direct-driven open-top transducer when using the
GUI.
NOTE: Texas Instruments recommends using the PGA460-Q1 EVM user's guide (this document)
after reading and following the steps listed in the PGA460-Q1 EVM Quick Start Guide. To
download this guide, go to the product folder: www.ti.com/product/PGA460-Q1.

Page 3: Introduction
Introduction The PGA460-Q1 EVM is a fully assembled evaluation module (EVM) designed for the combined evaluation of the PGA460-Q1 ultrasonic-sensor signal conditioner IC, an ultrasonic transducer, and center- tap transformer or half-bridge driver. Because of the two driver options, the user can evaluate any two pin, open or closed top ultrasonic transducer in the operating frequency range of 30 to 80 kHz, or 180 to 480 kHz. -

3.6.2.2 Time-of-Flight Converter Because the PGA460-Q1 device is intended for use in time-of-flight calculations, the time-of-flight converter is used to compute a distance or round-trip time equivalent for the user input variable. Speed of sound is assumed to be 343 m/s at room temperature by default. The speed of sound can change across temperature and humidity. - Page 40 The coefficient values of the band-pass filter (BPF) of the digital signal processing block are automatically calculated and updated by the PGA460-Q1 device for the low operating frequency range of 30 to 80 kHz.
