I need to find some sort of chip that can be programmed to take digital input values in order to output a few volts on different pins. Any ideas of a simple chip that can be used for this? I would need 3 digital inputs tied to 3 outputs.
A little more information, what is desired nature of the output? Various analogue etc?I need to find some sort of chip that can be programmed to take digital input values in order to output a few volts on different pins. Any ideas of a simple chip that can be used for this? I would need 3 digital inputs tied to 3 outputs.
But analogue output?Almost any MCU can do that. The 12Fxxx chips have 5 i/o pins and 1 input only pin which should suffice. If you go that route, I would suggest the 12F1840 (and related) chips. If you want/need more pins, the 16F1829 and related will give that.
What do you see as a difference between a digital input and an output based on that?I need to find some sort of chip that can be programmed to take digital input values in order to output a few volts on different pins.

Yes, some have DAC, including both the 12F1840 and 16F1829, but more realistically a simple PWM with low-pass filter will work too.But analogue output?
Max.
