Again, this is ideal for recording the signal through the analog input of the dsPIC. The gain of the op-amp at higher frequencies can easily be modified by changing the ratio of R3 to R4. For example, replacing R3 with a 100 kΩ resistor would increase the voltage gain by a factor of 10 (approximately) at audio frequencies.

I am using the 16 bit audio DAC from dsPIC33FJ128GP802 and I am having a lot of noise, even if the output value is held constant. I have obtained better results in the past using 8 bit PWM from an ATmega328. I have already checked that the power supply is properly filtered, also that the analog circuitry is properly working without adding any noise.
Audio DAC of dsPIC for non-audio purpose? | Microchip

RE: Audio DAC of dsPIC for non-audio purpose? 2009/02/03 10:08:53 0 hi jay_mchp, this is the document i was working with, but the code is for example using DMA access, i just want a simple example where i put 0xFFFF in the register and i have the maximum voltage in the positive output, or if I put 0x0000 I have the minimum voltate.
comp.dsp | dsPic adc for audio signals

dsPic adc for audio signals Started by Unknown April 15, 2006 Chronological Newest First Hi. With a dsPic (ie dsPic30F4013) I need to process two voice band channels (for telephony, fs=8kHz). Can there be problems to use the embedded adc, oversampling 8 times and then filtering? Do you think this may waste more than one half of dsp bandwidth?
