Hello Jagdish,
Based on the PGA4311 data sheet maximum specs, you should allow for 25mA quiescent current per device. This results in 300mA from I Q alone.
However, your load current can not be ignored. Calculate your maximum load current based on…

Hello,
I'm using the PGA2311 in a product for approx. one year and it worked like a charm. No noticeable noise when changing volume. After the first two batches…

Part Number: PCM1792A Other Parts Discussed in Thread: PGA4311 , OPA1611 Hello,
I'm working on a I/V stage for PCM1792A with differential ouput.
I'm simulating on TINA (.tsc file below) and the level of THD calculated by TINA is very high (about 0…
Hi Sumeet,
This seems similar to (or is?) an audio transducer. For 1 dB attenuation variation PGAs that are separate from the ADC, we have PGA2500 and PGA4311 . Our latest PGA ( PGA855 ) has great performance but fewer gain steps. Newer ADCs such as…
Hi Paul,
You point the right issue!
After a iron solder and strap session my amp is playing music!
First time I build a DAC, on scope FFT I see 80dB THD full power @ 10khz looks good ! At 1Khz only the noise floor.
A big thank to you, you save…

Hello,
I'm designing an high end power audio amp and the design step is DAC. Then I have some questions regarding the use of PCM1792A. I feed my…
Hi Stephen,
The PGA4311 EVM uses standard RCA jacks (see en.wikipedia.org/.../RCA_connector) . They have a 3.2mm inner diameter and a 9mm outer diameter. These are not the same as the 3.5mm (1/8") tip/ring/sleeve style connectors typically used for headphone…
