Does anybody know a chip (not MCU) that generates one or more
PWM-signals with more than 12-bit resolution and accepts I²C, SPI, ...
from an MCU.
I can only find 8-bit PWM devices from Philips and National, and MCU's
with 16-bit PWM. Reprogramming the code for another brand of MCU (with
16 bit PWM) is the last option.
