Demo Instructional
The Texas Instruments PGA450-Q1 small form-factor evaluation module (EVM) allows users to evaluate
the operation and performance of the PGA450-Q1 fully integrated system-on-chip analog front-end for
ultrasonic sensing. The small form-factor layout of this EVM is equivalent to that of an end-product form
factor, allowing users to easily integrate this PGA450-Q1-based sensor module into a real system without
the need for additional prototypes.
