Hi,
I am trying to run TAS5828M in hardware mode. There is no output. Below are some details I can share.
1. Connected R6 (Pin 13 - ADR (HW_MODE) to DVDD with 0Ohms resister to switch to Hardware mode. Voltage on ADR pin is 3.3V.
2. Pin 10, 11, 12 are connected to DVDD with pull up resisters with 10k, 15k, 10k value respectively. (used 1K, 10K pull up resisters for Pin-11, didn't work)
3. I am getting 13.50-16.60V on PVDD
4. Getting 3.3V on DVDD pins
5. Pin-5 (SCL/ HW_SEL0) is connected to DVDD, getting 3.3V on SCL Pin.
6. Pin-6 (SDA/HW_SEL1) is connected to GND (manually), getting 0v on SDA pin.
7. Voltage at Pin-11 is 0, even tho I have pull up resister of 10k connected to DVDD.
8. On PVDD, instead of 390uF, I am using 470uF capacitors.
9. 3.3V on PDN
10. ~5.07V on Pin-2 (AVDD)
11. ~5.13V on Pin-3 (GVDD)
12. ~3.3V on GPIO-2
13. 0V on GPIO1
14. 3.24 on GPIO0
15. ~3.28V on pin 14.
16. 4.48V on PIN 29,25,24,20
17. 2.6 to 3V on pin 30 & 19.
it seems I should get 1.5V on pin 14, but its ~3.3V and also voltage on Fault pin (pin-11) is always 0V.
Attaching the schematic I am following.
Any help would be appreciated.
