Analog output PICs

[Shohadawy]

Is there any version of the PIC series that has an integrated D/A converter ( Analog outputs ) ?

 

[Nigel Goodwin]

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.

Both of those options will work but if the impedance of the load you're driving is low, you'll need a buffer.

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.

The PIC also needs to be powered from a stable 5V supply.

Cretan dsPIC33F have a built in stereo 16bit audio DAC.It even includes a buffer on the DAC.

Really? That's the first I've heard of it.

It looks expensive.

It looks expensive.

Prices range from $3.67 to $4.18 each in 10,000-unit quantities.

Check out 16F88. This PIC has one anlog output(AN2)

Check out the date! - it was over three years ago!.

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.

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.

Oh, yikes. Sorry--I guess that's what you meant by "look at the date" Very sorry about that.
And I guess I misread the original post. Thanks for pointing that out, Nigel.
