Other Parts Discussed in Thread: PCM1798 , NE5534 Hi, I have implemented exactly the measurement circuit in figure 23 of the PCM1798 data sheet (SLES102A, page 18). However, when I try to give an I2S input, the output pins (17,18, 25, 26) go immediately…
Other Parts Discussed in Thread: PCM1798 Hi, I have constructed the measurement circuit from Figure 24 of the PCM1798 datasheet (SLES102A, page 19). What is the recommended test-load at the output, in order to make measurements? I am considering a large…
Other Parts Discussed in Thread: PCM1798 , NE5534 , OPA604 Hi, I have constructed the PCM 1798 (same pinout as PCM 1794) recommended application circuit on a solderless breadboard, using the recommended op-amps and component values from the data sheet. …
hi chris,
sorry i can't share full schematic here.
left is G=-1,right is G=2.
I did see your post regarding the PCM1798. Have you been able to rule out the DAC? It looks like you have made progress from that stage given the -125dbc measurements at…
Other Parts Discussed in Thread: PCM1798 Hi,
I'm currently struggling with an issue with PCM1798s whereby on some of our prototype units the we get a dynamic range of 114dB unweighed, while others give 110dB. Upon reconfiguring the clocks for an alternative…
Other Parts Discussed in Thread: PCM1798 Dear,
In the PCM1798 data sheet is stated: "Differential Current Output: 4 mA p-p" Further in the data-sheet is stated: "The current of the PCM1798 on each of the output pins (IOUTL+, IOUTL-, IOUTR+, IOUTR-) is…
Other Parts Discussed in Thread: PCM1798 Hello,
Can we use PCM1798 for mono mode? Is there any application note that describes how to use PCM1798 in mono mode? What will be the signal level?
Thanks,
Madhu
Other Parts Discussed in Thread: PCM1798 , PCM1794A , TAS5624A , TAS5508C , PCM1794 , TAS5624 , TPA1517 Hi,
Can I use PCM1794A (FL/FR) with 2 more PCM1798 for a full 5.1ch? Not sure if this will cause any delay effect between both chips. So i'm guessing it should…
Other Parts Discussed in Thread: PCM1730 , PCM1798 I am replacing a PCM1730 with PCM1798 as recommended by TI. The PCM1798 seems to have a DC offset current that the PCM1730 does not. Look at the PCM1798 data sheet reference circuit Fig 24. My pcb has only…
