Looking for a microcontroller with ADC recommendation

I'm looking for a microcontroller to interface with a few strain gauges and cut out the intermediate amplifier and ADC. I know that a lot more is being integrated into the microcontrollers these days and SoCs are pretty common for every application.

So if I wanted to remove the amp/ADC external compontents, I need to find a microcontroller that can provide a decent ADC with PGA. Does anyone know of any?

My requirements:

  • Low power microcontroller (<5uA standby)
  • 3ch. differential ADC with good noise filtering(16-bit or higher)
  • on-board Programmable Gain Amplifier (x64 gain or higher)
  • Not too expensive (<$3.50 @1k)
  • SPI, I2C, UART
