Hi, All!
Could you please recommend audio amplifiers solution for mono recorder / player with following characteristics:
  • electret mic
  • dinamic speaker 0.3W
  • power voltage 3.0V
  • shutdown possibility is neccessary
  • not so expensive
  • will be used with STM32F3 12bit ADC & DAC for recording short voice tags to waypoints

Currently I'm looking for TS472 mic preamp and class-D or AB BTL speaker amp. Might is be a better solution?

BTW, is it possible to contol TS472 gain by MCU?  Or add a limiter?
