Most of these are class D unless noted. I like class D most of the time.
National series
- LM386 noise outdated analog pretty cheap inefficient class AB but not really cheap compared to better newer amps
- LM4853 "Boomer" costs too much, love that product line name "Boomer" I mean ???
- LM48560 piezo / haptic driver
- TDA2050 high output obsolete class AB
- TDA2822 $4.5 obsolete
- TPA2012 see adafruit
- TPA2016 has a control channel over i2c which is pretty neat, I think Adafruit has a breakout for it
- PAM8302 mono chip is around $.40 Adafruit breakout is $3.95
- PAM8403 very common very quiet obsolete I have 2 from All Electronics
- PAM8406 upgrade to 8403 chip is $.84 and boards run around $1-$10 I ordered a couple spendy ones from Amazon, about $7 each
The PAM8406 has a mute control and a mode control (Class AB or Class D) and sometimes those pins are not brought out. The board I bought today has a 2 gang volume knob and those signals are available.
There's a MAX58937 or something from Adafruit that has an i2s input instead of analog. It's around 3W
I have several i2s 20W boards including one in my junk box
