How can use MP45DT02 and CS43L22 DAC with STM32F4?
It appears to be a device with digital output using PDM (Pulse Density Modulation), which is the 1-bit oversampled output of a sigma-delta ADC-- it's similar to what's used in SACD. A microcontroller should be able to convert it to the more usual PCM format by digital filtering and resampling, provided it has enough processing power. Since the CS43L22 appears to take PCM data for input, you have no escape but to perform this conversion if you want to use it.

An alternative, which I believe should work, is to just output the data digitally via a GPIO, perform analog filtering (lowpass filtering at a cutoff of, say, 20 kHz), and then input it to an audio amplifier.
