I'm looking to use a PAM8406 in Class-D mode, with only the left channel active.
The datasheet doesn't discuss how to handle unused pins for the right channel to "deactivate" that half of the amp.
- Should I connect INR, OUTR+ and OUTR- to ground?
- If not, what can I do to ensure the right channel isn't operational?
Additionally, I plan to provide 3.3v to the amp to a 2Ω load, which yields about 2W amplification per chart 17:
Given 3.3v at 2.2w, this means an amperage draw of about 666mA (not accounting for efficiency, etc), right?
Is that amperage draw per channel or combined? If it's combined, this means an amperage draw of 333mA in mono mode, correct?
