The PGA460-Q1 EVM is a collective of the BOOSTXL-PGA460 and MSP-EXP430F5529LP, which enables users to fully evaluate the PGA460-Q1 ultrasonic sensor signal conditioner with an open-air transducer. Transducer compatibility is expanded to open- or closed-top transducers operating between 30-80kHz and 180-480kHz. Driver strength can be controlled by current limiting the transformer or direct driver mode to generate the maximum sound pressure level during echo transmission. The receiver can be tuned to filter and process returned echo data for post-measurement analysis. The associated PGA460-Q1 EVM GUI can be used to customize, configure, and control the ultrasonic setup, and monitor the performance of the resulting ultrasonic activity. The BOOSTXL-PGA460 includes one transformer driven closed-top transducer, and one direct driven open-top transducer for comparison.
