Part Number: PCM1809 Hi
I made a board on JLCPCB website with PCM1809. The part is purchased from LCSC stock.
MSZ = 0 target mode
FMT0 = 0 i2s format
MD0 = 0 linear filter
MD1 floating
I checked with the scope that the two input pins BCLK…
Part Number: PCM1809 Hi team,
The PCM1809 is a 2-channel ADC. If only one channel is used, could you please advise on the recommended handling of the unused channel pins?
We assume that the analog input pins should be connected to a stable reference…
Part Number: PCM1809 Other Parts Discussed in Thread: PCM1808 I have designed a circuit with PCM1809. I am using it as the controller and I am supplying the 6MHz master clock on the MD1 pin. I have a 500mvpp 4KHz signal on the IN1P and IN2P pins (signal…
Part Number: PCM1809 Tool/software: Hello TI Support,
I would like to use the PCM1809 to sample analog audio and convert it to I2S. My application requires a 192kHz sampling rate.
Could you please confirm whether the PCM1809 supports 192kHz operation…
Part Number: PCM1809 Hi team,
Regarding the MD pin, it's understood that leaving it open-ended is acceptable, but could this introduce noise into the signal? Is it internally isolated from the analog circuitry?
Best Regards, Ryu.
Part Number: PCM1809 Hi team,
The recommended input impedance is approximately 10 k ohm, but are there any guidelines regarding the minimum and maximum values?
Best Regards, Ryu.
Part Number: PCM1809 Tool/software: Hi ti team，
Does PCM1809 not need MCLK ?
If necessary, which PIN should I connect to ?
Do I need to directly connect PCM1809 and PDM MIC ?

Data sheet Figure 7-1. Two-Channel Analog Microphone Recording Diagram for 3.3-V AVDD Operation no external AC-coupling capacitors, are there any special technologies?
Part Number: PCM1809 Tool/software: Hi team,
What is the maximum capacitance value for a bypass capacitor that can be connected between pin 18 (VREF) and pin 14 (DREG) and pin 17 (AREG) ? Also, is it possible to use an electrolytic capacitor?
Are…
Part Number: PCM1809 Hi team,
In another thread, it was mentioned that during target mode, MD1 can be left open or grounded. However, is there no risk of external noise affecting MD1? Since MD1 can be left open, is it internally processed to be isolated…
