View ArticleForum Post: DAC8560 power-down time from full power mode
Hello,The datasheet for the DAC8560 states a power-up time of 2.5us from power-down when operating from 5V and 5us when operating from 3V; however, the power-down time is not specified. Is the time...

Hi,Yes, a one-time SYNCIN would be sufficient after the ADC has had time fo power up. Now if you are using the SYNCIN to synchronize multiple ADCs, then the SYNCIN pulse must be provided to all the...

i connected the GND1 and GND2 loops to common ground. I'm not sure why i needed to do this, but it fixed my problem.
View ArticleForum Post: RE: PCM3070 dedicated programmer
The PCM3070 doesn't have non-volatile memory therefore it needs to be programmed after each power cycle or reset through its control interface (either SPI or I2C). This is usually done by a SoC or uC...

Hi Joannes,Make sure all of your timing agrees with the timing diagram of Figure 1 of the datasheet. For example, you must hold CS low for 7 tosc periods ( approximately 1.7us for 4.096MHz operation)...
