Other Parts Discussed in Thread: PGA2505 , OPA1632 Looking at the PGA2505 datasheet, Figure 17. This shows the connection if using the OPA1632 output buffer before going to the A/D. If I am not mistaken is the the polarity between the OPA1632 and the A…

Other Parts Discussed in Thread: PGA2505 Hello,
I believe there is an error in Figure 13 of the PGA2505 data sheet . The 4.7uF polarised capacitor attached to VA- (pin 17) appears to be connected the wrong way round.
I would be interested to know if my…
Paul,
We have audio PGA devices such as the PGA2500 and PGA2505.

Part Number: TLV320AIC3254 Other Parts Discussed in Thread: PGA2505 Hi Team,
Our customer is developing a video doorbell-type device that will need to have voice input into a microphone.
The TLV320AIC3254 application schematics don't necessarily show…
great thanks for letting me know Chris.
I just discovered this in PGA2505 datasheet ( same PGA as PGA2500 but with less gain steps ).
In this diagram there is no attenuation before OPA1632 and with the 2.5v bias from the ADC connected to the OPA1632. …
Part Number: PGA2500 Other Parts Discussed in Thread: PGA2505 Hi all
My customer is looking at the PGA2500 / PGA2505 and has bought the EVMs. So far they haven't been able to make this work due to the parallel interface and SW that is only running on…
To follow up my questions from yesterday:
If I can't use the internal analog PGA when the ADC6140 is in active mode, is there a TI part you can recommend that could potentially do this as an integrated digitally controlled front end? Noise from zero-crossing…
