TI's MSPM0L1105 chip offers 32MHz and 4kB SRAM + 1x OpAmp for $0.39 / 1k quantities.
  • Thanks for posting this! I’m particularly excited about the use of the opamp as a transimpedance amplifier, converting a current from a photodiode to a voltage, then being able to feed that signal straight into the ADC. Depending on the performance, this could simplify my design work significantly.

    I found some basic documentation on that here - https://www.ti.com/lit/an/slaae81/slaae81.pdf?ts=1689294975621
