TUSS4470TRTJR Description

Short technical summary and product information.

The TUSS4470TRTJR is a highly integrated analog front-end (AFE) designed for ultrasonic sensor applications. It offers direct drive capability for transducers and includes a receiver stage with analog output. Key electrical specifications include a gain range of 19 to 113 dB and an 86 dB input dynamic range. The device features a configurable bandpass filter from 40 kHz to 500 kHz and supports transducer frequencies from 40 kHz to 1 MHz.

 

The TUSS4470TRTJR operates within a temperature range of -25°C to 105°C and communicates via an SPI interface. It is available in a 20-QFN (4x4) package, suitable for surface mounting. The IC includes features like a configurable drive stage, supporting direct drive or pre-driver configurations for external FETs, and configurable burst patterns.

 

This ultrasonic sensor AFE is designed for applications requiring precise distance measurement and object detection. Its integrated driver and receiver stage simplify system design, while low power consumption in standby (1.7 mA typical) and sleep (220 µA typical) modes make it suitable for power-sensitive applications.
