Other Parts Discussed in Thread: PGA900, PGA309, PGA308, PGA300

Hi team,

The customer would like to use PGA900 to deal with a dynamic pressure signal. The frequency of the pressure signal is 10KHZ.

He would like to deal with the temperature nonlinearity compensation.

PGA900 cannot meet the customer's requirement since the max output sample rate of the pressure ADC is15.6kHz.

For the customer's requirement, would you recommend a suitable device? Is PGA300 ,PGA308 or PGA309 OK?

Best Wishes,

Hi Mickey,

The PGA300 is essentially just a preprogrammed PGA900, and has the same analog characteristics that make the PGA900 unsuitable for this application.

I have notified the applications engineer responsible for the PGA308/309, and they should be able to give you a better response regarding these devices' compatibility in your customer's system.

Hello Mickey,

Given the information on this thread the PGA309 and PGA308 should be able to meet the requirements. Do you have more information on the application and specifications of the signal chain?
