Transformer drive ultrasonic sensor IC with logarithmic amplifier evaluation module

Overview

TopologyOther Topology
IC revisionA

Description

The BOOST-TUSS4440 (+ MSP-EXP430F5529LP) evaluates the TUSS4440, a transformer driven ultrasonic IC with integrated logarithmic amplifier. The associated TUSS Generation III EVM GUI can be used to customize, configure and control the ultrasonic setup, and monitor the performance of the resulting ultrasonic activity.

Features

  • Compatible with open- or closed-top ultrasonic transducers operating at frequencies between 30 to 1000 kHz.
  • Able to generate maximum sound pressure level using a transformer driver.
  • Control the drivers directly via MCU for complete customization of the burst signal or program the drivers via SPI with customizable burst length.
  • On-board small form factor detachable solution to showcase end-product equivalent size.
  • EVM includes GUI, one closed-top transducer, quick start demo procedure, USB interface and firmware, and detailed user's guide.
