TPA2017D2: Input without AVDD

Kazuto Tatsumi

Part Number: TPA2017D2
Part#: TPA2017D2RTJR

Hello,

The TPA2017D2 can be destroyed or latched up in case the input AGC1/AGC2/EN is changed to HIGH without AVDD?

Some other ICs may be broken by such operation without VDD.

Tatsumi-san,

As stated in the datasheet, EN, AGC1 and AGC2 support a maximum voltage range from -0.3V to 6V and they are not dependent of VDD. By other hand, the analog inputs INR+, INR-, INL+ and INL- depend of the VDD level, and you would need to pay attention to their voltage level when AVDD is disabled.

I hope this helps you. Please let me know if you have additional questions or comments.
