Микроконтроллеры PIC

Дык есть dsPIC33 со встроенным ЦАП 16 бит * 2 канала, 100 кГц max The digital interpolator up-samples the input signals, where the over-sampling ratio is 256x which creates data points between the user supplied data points. The interpolator also includes processing by digital filters to provide noise shaping to move the converter noise above 20 kHZ (upper limit of the pass band). The output of the interpolator drives the Sigma-Delta modulator. The serial data bit stream from the Sigma-Delta modulator is processed by the reconstruction filter. The differential outputs of the reconstruction filter are amplified by Op Amps to provide the required 2 volts peak-to-peak voltage swing into a 1 kOhm load.
