S Shohadawy New Member Sep 24, 2008 #1 Is there any version of the PIC series that has an integrated D/A converter ( Analog outputs ) ?
Nigel Goodwin Super Moderator Most Helpful Member Sep 24, 2008 #2 I've not seen any, but many have hardware PWM which can be used, followed by a low-pass filter (which a normal D2A requires anyway). Or you could use 8 pins to feed an R2R ladder, giving 8 bit resolution.

Click to expand... The required filter can act as the buffer, it really needs to be an active one in any case - the same also applies to using an IC D2A as well.

Someone Electro New Member Sep 24, 2008 #6 Cretan dsPIC33F have a built in stereo 16bit audio DAC.It even includes a buffer on the DAC.

DerStrom8 Super Moderator Nov 10, 2011 #12 The 18F1330 has a built-in 10-bit A/D converter module. And those chips are quite a bit more recent than the 16F88 I have had great success with the ADC on these chips, and have used it in several applications. IMO it's definitely worth looking into.

Click to expand... So, you're not only responding to a three year old post, you're also doing it completely wrongly!. The thread is about D2A - NOT A2D. A great many PIC's have multi-channel 10 bit A2D, as does the 16F88 mentioned.

And I guess I misread the original post. Thanks for pointing that out, Nigel.
