Part Number: PCM1803A Other Parts Discussed in Thread: PCM1803 , TPS54308 Hi,
We understand that the voltage difference between VCC and VDD must be within 3.0 V, because PCM1803A is a Specificaion-1 device. But the customer cannot use the way to drive 3…
HI Akio-san,
Yes the PCM1803 should belong to the Specification-1 products as they are similar to 1802/1804 which are listed in the document.
Best regards,
Ravi
Part Number: TAS6424L-Q1 Other Parts Discussed in Thread: PCM1803 Hi,
Ok, I have good timing inputs using PCM1803 and am beyond that problem. No "timing error" with this source.
However, the amp. chip gets warm and toggles the over heating error…
Other Parts Discussed in Thread: AMC7812B , PCM1681 , PCM1803 , AMC7834 , AMC7836 Hi E2E,
I have a customer who's evaluating the AMC7812B to replace the PCM1681 and PCM1803 due to their poor DC performance. How's the DC performance on the AMC7812B?
…
Just to clarify, do I apply 5V Vcc to Vref2 (along with decoupling caps), and bring out Vref1 (and decouple it) to use as my ref for signal conditioning my bipolar signals to be 1V to 4V (3Vpp, centered around 2.5Vref)?
On the PCM1803 dev bd, Vref2 is…
For this same question, we are using DVRRDK4.0 with PCM1803 24 bit. Since PCM1803 does not need any codec side configuration, we just re-use the tvp5158-audio driver. Below is our code:

Other Parts Discussed in Thread: PCM1803A , PCM1748 , PCM1803 , PCM1789 Hello.
I have a question about the ground connection of the PCM1803A. Is normal that internally the analogic ground pin have continuity with the digital ground pin, measured without connect…
Hi Hirotaka,
1. No as the power down pin is not the reset pin, you do not have to toggle it. The PCM1803 has an internal reset, so when the device is powered, it will stay in reset until it receives 1024 system clocks then it will come out of reset and…
Other Parts Discussed in Thread: PCM1803A , PCM1803 The feature list on the PCM1803A pages states:
Single-Ended Voltage Input: 3 Vp-p
The data sheet for the PCM1803A states:
Analog input voltage, full-scale (–0 dB) 3 Vp-p
It also states:
The differential…
Hello Lee,
PCM1802 offers 105dB Dynamic Range with -96dB THD
PCM1803 offers 103dB Dynamic Range with -95dB THD
PCM1802 also includes the analog anti aliasing filter down to 300kHz, which is a significant advantage. (and is costly to add in silicon)…
