Forum Post: RE: PCM3070 - Audio Mixing configuration
Winnefred,Here is an example script for analog stereo PGA bypass. You'd need to modify it for ALDO use and for your specific routings.For SPI, ignore the '30'. The second byte is the register value in...

Hi Bailin,I recommend taking a look at pages 30-34 in the ADS1278 datasheet. You'll see that there are multiple modes you can use to output the data.In general, you have more control and more options....

Thank you for that information Kevin. I can certainly give the shutdown option a try but high z out may not turn off my NMOS very fast. If using 10 bit 100 Hz PWM as I originally stated, it's...

Hi RyujiYou are correct, the test pattern goes in sequence D15, D14, D13, D12, ..., D2, D1, D0, D15, D14,... continuously repeating until it is disabled.If the ADC test pattern is enabled and active...

Hi David,Those are SPI commands sent to the ADC to write to the CONFIG1 and CONFIG2 resigsters. See table 19 and table 20 in the data sheet.Regards,Chris

If you AC couple the input, the signal will be automatically biased to the correct voltage which is 1.35V. Or you can externally bias the inputs to 1.35V.

Hi Samuel,Just to make sure I'm clear on what you are doing, A0 and A1 are not tied together right? Did you mean that on both ADS1234 the A0 pins were tied together (and the A1 on both devices tied...

John,The only thing that would limit bandwidth in any way concerning the R-2R ladder itself are various parasitics, there are no elements in the design to purposely limit the bandwidth of the R-2R...

Hi Stefan,The 32k sample limit is from the internal memory in the FPGA. The ADC12D1800RFRB has no on-board memory, but there is an option to stream data off the board continuously and make a deeper...

Hi David,If you're observing the correct SPI operations on the oscilloscope, you're probably reading the correct value.0xFFFF9F is a small negative number. This would correspond to -28.9uV (using the...
