Hi all,

Can any of you recommend a D-to-A converter with a single-wire=20
digital-side interface?  As small as possible -- roughly SOT23-5 to=20
SSOP-8 would be good, 5V powered, 0-5V output (I'll actually do 0.5V to=20
4.5V output with it).

Summary is that I need to add an analog output to an existing=20
PIC16F883-based circuit (already working on PCB), but only have one=20
general-purpose I/O available, and no PWM pins available.  I can get=20
tons of I2C, SPI or other D/A converters, but not finding anything with=20
actual single-wire serial.  FWIW, there's too much going on in the chip=20
to get any decent bit-banged PWM.

I can do this with a small PIC, but since I only need 25 or so of these,=20
I thought I'd check to see if anyone here knows of a purpose-built chip=20
for this, so that I can save coding time.

Cheers,
-Neil.
