TI are iterating on "universal opamp" with others like OPAx828, or chopper OPAx189 lots of progress with analog capabilities still growing.

Wow.  Those are some impressive specs..

THD + noise 0.00006%  :scared:

Meanwhile they provide PowerPAD packages for opamps to reduce self-heating. Amazing how improvements in analog technology still continue.

I'm not sure if this is officially a chip of the day considering I haven't personally use it yet... but

This one could be super useful.....

TPL5110QDDCRQ1

It's a timer/power gating high side switch chip.  So for example if you want to only power up your system every x seconds, do something, then power down to save batteries.  Timer intervals from 100ms to 7200s and 35nA quiescent current draw for this chip.  Could be super useful if your system doesn't have a deep sleep mode or otherwise lots of quiescent current.
