TLV320AIC3007: Class D output protection

Kazuto Tatsumi

Part Number: TLV320AIC3007

Hi team,

Does the Class D output have any protection? The sound from the speaker is stopped (no PWM) when the loud signal is played with high gain. The high gain setting is necessary to achieve clipping below 0dBfs.

Hi,

If the gain configuration and output level is following the data sheet setting, they should work and not damaged the part.

No output could be caused by many things. Is this not working even after recycle the power?

Page 46 of the data sheet provide more info of the class D driver.

Regards.

Hi pdjuandi,

The customer doesn't write these registers. The left side mean an address and the right side is a data, correct? What is the page number (0/1)?

And it should be written every time just before the Register 73: Class-D Control Register, otherwise only at the startup initialization?

Regards,
Kazuto

Hi Kazuto-san,

The page is in the sequence, so execute these writes prior to enabling the class-D amp every time.
