Part Number: PCM1864 Hello TI experts, While working on a maintenance firmware release for one of our more popular products, I decided to look into a bug that is seen only on a very small percentage of the manufactured units. The failing units appear to…
Part Number: PCM1864 I input 0V for the IN+ terminal of this ADC and 3.3V for the IN - terminal .
I set channel gain As 0dB, No high pass filter.
The data getting from ADC is: 0xD25080。
As the input range of ADC is 4.2Vrms， the data must be 0xB8DFE1. Why…
Part Number: PCM1864-Q1 Hello team,
For the power-on reset timing diagram in PCM1864-Q1 datasheet,
-. Could you please explain what the “REF Fast Boot” means?
-. At the actual measurement below, the VREF’s behavior seems different from the…
Part Number: PCM1862 Other Parts Discussed in Thread: PCM1864 , Hello,
I changed from the PCM1864 to the PCM1862. Analog input pins 1L and 1R are used and muxed to the first Audio ADC, but both Digital outputs DOU and DOUT2 are used. When using the PCM1864…
Part Number: PCM1864-Q1 Hi team,
Would you please answer the following question?
Regarding Antialiasing filter, the datasheet recommends 100ohm/0.01uF for single-ended and 47ohm/0.01uF for differential. This is about fc=160kHz. When considering audio…
Part Number: PCM1864-Q1 Hi team,
Would you please check the In/Out configuration of PCM1864-Q1?
A customer wants to use DOUT for input#2, input#3 and DOUT2 (GPIO3) for input#1 from MIC using I2S mode.
In that case, the following configuration is correct…
Part Number: PCM1864 Hi,
