Part Number: TLV320DAC3120 Tool/software: Hi team,
Please tell us some of them. 1) Are there any requirements for power on and off sequence? 2) What should we do if VOL/MICDET, AIN1, and AIN2 are not used? 3) Is it possible to prevent POP noise during power…
Part Number: TLV320DAC3120 Hi All,
Would like to know about speaker output pins of DAC(TLV320DAC3120). Here is our schematic picture.
Could anyone please let me know the correct values of that ferrite(E18 & E19) and cap(C74 & C137) values.

Part Number: TLV320DAC3120 Hello,
As part of a system selftest, I'm trying to reliably test that the speaker isn't shorted.
I'm trying to detect a shock in 2 ways:
After I turn on the class D power stage (P1R32), I wait 500 ms and then read…
Part Number: TLV320DAC3120 Hello,
I am trying to implement a biquad filter on the TLV320DAC3120. My initialization sequence is as follows:
hardware reset
wait 1ms
set P1R60 = 6 (DAC signal processing block PRB_P6)
set P8R1 = 4 (Adaptive filtering enabled…
Part Number: TLV320DAC3120 Hello !
Can I connect the exposed pad on the QFN package to 3.3V Vcc ? In my case, it would make layout much simpler.
Thanks !
Hi Lenio,
As discussed offline, I've noticed that the interrupt flag on Page 0 Register 44 is actually being enabled, the GUI has some issues when reading back the registers. Below I explain how to successfully read the registers, and also what are the…
Part Number: TLV320DAC3120 Hi team,
I hope you could help us with this. Our customer is using the TLV320DAC3120, however, the Class-D driver is not powering up. In this IC, there is no speaker output voltage(spkp1,spkM2,spkp2,spkM2), but I2C AND I2S Communication…
Part Number: TLV320DAC3120 Hi, I can't figure out why I my chip does not detect a headset. I'm already trying things at the lowest complexity: There is a 2k2 resistor between MICBIAS and VOL/MICDET. And I would expect an INT1 to be raised when I touch…
Part Number: TLV320DAC3120 Hi,
Could you please tell me how to change from the volume control with VOL/MICDET pin to the dac volume control with the register 65 of page 0 on the fly?
Best regards, Kato
