PGA450-Q1: Difference Between PGA450-Q1 and PGA460-Q1

Hi Kato,

In short, the PGA460 is superior in every aspect of performance (max single record range up to 11m instead of 7m), power consumption (offers 300uA low-power mode), size (TSSOP16 instead of TSSOP28), and cost ($1.65 instead of $2.60 at 1k units).

The primary technical difference is that the PGA460 operates as a digital state machine, so it is used as a slave only device. The PGA450 offers an integrated 8051, but the functions that are to be manually programmed into the PGA450 are now hard coded in the PGA460. The PGA460 offers additional features to optimize the driver strength and receiver filtering for both short and long range measurements.

What is your application, and how do you intend to incorporate an ultrasonic sensor? Based on the details of your project, I may be able to recommend the PGA460 versus PGA450.

Hi Kato-san,

For people-detection from 0.3~2m, the PGA460 would be the most appropriate device.

I recommend the customer view the available PGA460 collateral on the product page to better understand how ultrasonic can be used for this application, and also view the "Ultrasonic Sensing with the PGA460-Q1" video series ( training.ti.com/ultrasonic-sensing-pga460-q1 ) to visually see a demo of the PGA460 device in action.

After reviewing the collateral, let me know if you have any particular questions.
