I would like to create a 16 bit DAC in STM32F103RET6. But

STM32F103RET6

only has 12 bit DAC. How do I implement a higher resolution DAC in

STM32F103RET6

?

Thank you. Please see link below

So you'll have to connect an external CODEC or DAC device, or create one using a resistor ladder type configuration.

Resistive ladders are pointless for 16-bit DAC's - 1% resistors versus 0.0015% resolution for the DAC.

Use an external DAC.
