Hi Team,
Greetings for the day.
Please provide the power up sequence for TLV320AIC3253 Audio CODEC.
There are some unused pins in my design (INL, INR, MICBIAS, HPR, HPL) please suggest the best way to terminate these pins.
Regards,
Harikrishnan T
Hi Harikrishnan,
You can refer to the AIC3254 for power sequencing since the device is from the same family: https://www.ti.com/lit/an/slaa492a/slaa492a.pdf?ts=1724702759037
For unused input pins (INL, INR) AC couple the pins to GND via a 0.47uF or similarly sized capacitor. Do not short the pins prior to the AC coupling i.e. use two caps, one per each pin.
For unused outputs (MICBIAS, HPR, HPL) these can be left floating.
Best regards,
Jeff McPherson
