I tried to left it unitialized (default configuration), and now I tried to initialize via I2C (20pin tied to GND, 21/22-SDA/SCL, 0x98 i2c address) but it gives same result: no output - just 0.5xVCC. i2c config: i2c_write(16, 0xC0); i2c_write(17, 1<<7…
The spec for the THD+N for this part is given both as .001% and -94db. If I do my math correctly, 20 * log (.001%) is -100 db, not -94 db. So which is it? Also, can the analog VCC be run at 3.3v instead of 5V, and what degradation could one expect by…
Other Parts Discussed in Thread: PCM1789 I have an application involving a PCM1789, wherein the analog supply is not always available. As presently designed, the product can run for an indefinite period period of time with the digital supplies (VDD) at…
Hi Don,
I've surveyed the range of options. I do like the simplicity of the PCM5102 but in my application I need programmable digital gain. Looked like the PCM1789 was my best bet.
Any thoughts on the low pas filter design?

Hi,
We have obtained a request of EVM from our customers, are looking for EVM. So, we found "TTK reference designs for audio converters" as following.

Other Parts Discussed in Thread: PCM1870 , PCM1789 I use PCM1789 & PCM1870. PCM1789 & PCM1870 for CLK - SCKI : 12MHz, fs : 46.875 KHz, BCK = 3MHz I don't get certain data. I Know that don't support fs(46.875KHz). But 46.875kHz is similar to the frame…
Other Parts Discussed in Thread: PCM1789 Hi,
Our customers would like to control PCM1789 by using I2C control function of USB to I2X(TTK RevC). If you have the pc control software, could you please send us it?
Best Regards, Kato
Other Parts Discussed in Thread: PCM1789 What is the output settling time for PCM1789? I could not find it in the datasheet.
Also PCM1702 operating temperature is -25 to +85 C. Is there any the alternative DAC of PCM1702 which works at -40 to +85 C…
Other Parts Discussed in Thread: PCM1789 , PCM1804 We are seeing some distortion on our audio inputs that use the PCM1804 A to D from TI and on our outputs that use the PCM1789. I see users guides for the DEM-DAI1804 and the DEM-DAI1789 EVM’s but no way…
Other Parts Discussed in Thread: PCM1789 Hi,
I have a customer looking for an IBIS model for the PCM1789. Does not look like there is one - if not is theer an alternate one they could use?
Cheers
