Part Number: PCM2903 Hi!
I am using the PCM2903 ADC to digitize measurements. So my question is whether the digital output of the ADC is a digitalization of the Voltage (Volt) or the Power (Watt)?
Since these are not proportional: P = V*V / R
Part Number: PCM2906C Other Parts Discussed in Thread: PCM2903 , The customer is considering to choose PCM2906C or PCM2903.
The customer find the below three advantages of PCM2906C.

Part Number: PCM2903C Other Parts Discussed in Thread: PCM2903 , , OPA4353 , PCM2903EVM-U Hi there,
I'm running into an issue where the RCA output is not being detected on professional amplifiers such as Monoprice Unity and OSD XMP300. I checked with…
Hi Henrik,
Our ADC page is for devices that are exclusively an ADC. Devices like the PCM2903 are more what we would consider a codec, since it has a DAC in it as well. The PCM2903 and devices like it are part of our USB Converter portfolio, which have…
OK. So I can put the JFET2140 in front of the INA849 or put the OPA211 or the OPA145 after the INA849 in order to amplify my very weak signal about a 1000 times more before it enters the PCM2903. The 'million dollar' question is which of the 2 solutions…
