Part Number: PCM1795 Hello,
Total Icc current consumption specification is 18mA(typ) @44.1KHz on the datasheet.
There are 3pins(#15,#23,#28) connection for analog Vcc +5V power supply.
Our customer try to add independent noise de-cupping RC filter…
Hi Paul.
I'm sorry, but what you ask is almost impossible. The transistors are packaged in a TSSOP6: their body measure 1.2mm x 2.2mm, the pich among pins is 0.65mm. Lifting a pin of it from the printed circuit board is impossible for me without risking…
I don't know if there is a hard-and-fast rule for this. I think PCB layout would have more of an impact. I would recommend you buffer the clock signal before it has to go a long distance geographically. Maybe have a few buffers at the clock origin, one…
Part Number: PCM1795 Hello,
I am using the PCM1795 and I am supplying clocks and data but don't get an analog output. All analog outputs are at a current of -1.2mA no matter the digital input. Some more parameters of my setup:
* 32bit, right-justified…
Part Number: PCM1795 Hi,
For PCM1704, the topology of R2R DAC is applied. So, the output impedance 1kohm is specified in PCM1704 datasheet.
For PCM1795, the output impedance isn't specified in PCM1795 datasheet because of the difference between…
Hi Paul-san,
Thank you for the detailed information.
I will contact you if I get additional questions from our customer.
I greatly appreciate your cooperation.
Best regards, Kato
Hi Michallick,
The output of PCM1795 is 4mApp and their desired swing voltage is 2.8V. This is because they choose 700ohm.
Why do you think 700ohm is rather low? For stability?
Best regards, Koyo
Part Number: PCM1795 Dear Sirs,
My customer asked me about behavior when power off for PCM1795 as follows.
Is there a problem when the RCK / DATA / BCK / SCK input communicates when the power is OFF? Is there a provision for the power off sequence…
Part Number: PCM1795 Hi All,
I am trying to run the DAC in the application like attached. The very strange thing is that it seems to be 5 bits only, please see attached screenshots from the scope. For the purpose of this demo I played 1 kHz 0dB sine…
