The TUSS4470 is a highly integrated direct drive analog front end for industrial ultrasonic applications. The transducer drive stage is an internal H-bridge that can be configured to drive the transducer in direct-drive mode to achieve maximum voltage across the transducer. The internal H-bridge can also be configured as a pre-driver for external FETs, enabling higher current and voltage drive for larger transducers.
The receive signal path includes a low-noise linear amplifier, a bandpass filter, followed by a logarithmic gain amplifier for input dependent amplification. The logarithmic amplifier allows for high sensitivity for weak echo signals and offers excellent input dynamic range over full range of reflected echoes.
The drivers can be controlled directly through the microcontroller for complete customization of the burst signal, or can be programmed through SPI with a customizable burst length. The TUSS4470 can support a single transducer to send and receive burst signals, or can set up two transducers to split the send and receive functions.
