PGA460PSM-EVM: PGA460PSM-EVM as sonicator

Hi!

I am developing a devide to produce foam in beer using the ultrasonic transducer UTR-1440K-TT-R (a sonicator). I would like to know if this device (PGA460PSM-EVM) is capable of producing foam in beer using ultrasonic waves.

I know that it is an evaluation board for ultrasonic sensors, but I need something to start and I would like to know whether it will serve to my purpose or not.

Many thanks,

Íñigo

Íñigo,

We have never tried using the PGA460 in an application to produce foam for example. We typically use the PGA460 for time-of-flight measurements. Note: Given the number of pulses is limited to a maximum of 31, you would need to send a UART or SPI command every 775us (31 / 40kHz) to continuously burst, or burst beyond 31 pulses, which is likely necessary for this type of application.

The PGA460 is a driver and receiver IC, but you only need the driver portion. We currently do not have a device that is driver exclusive at this time, so a discrete driver would be an alternative for you to consider. You are welcome to try using the PGA460PSM-EVM with the UTR-1440K-TT-R transducer, but I am unable to comment on whether this transducer is feasible for foam production. You may need to contact transducer suppliers for a specific transducer recommendation.

Íñigo,

An alternative device to consider is the TUSS4440 or TUSS4470. See my explanation of how these devices work in a driver-only implantation in the following E2E post for a similar application: https://e2e.ti.com/support/power-management/f/196/p/906573/3354055#3354055
