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.

The PGA450Q1EVM-S is a fully assembled PCB design for real-world evaluation of the PGA450-Q1 ultrasonic-sensor signal-conditioner device, an ultrasonic transducer, and step-up transformer. This EVM can be integrated with systems for general object detection and distance measurement through air, in applications such as automotive park-assist, level sensing in tanks, collision avoidance for autonomous robotics, and unmanned aerial vehicle landing assist. This small form-factor EVM is intended to act as an ultrasonic module alternative to the full-scale PGA450Q1EVM. TI recommends that the user first begins evaluation with the PGA450Q1EVM before transitioning to evaluation with the PGA450Q1EVM-S.
