Which PIC should I use?

    I'm searching for a PIC having two analog inputs. I heard that there is a PIC having that capability, but I can't find none. I tried google, but to no avail. Does anyone know about a series of PICs containing analog inputs? It is to be used for an amplifier project, as a smart protection. It should sense the input signal and the output signal, and compare both. Should a DC fault (case one of the output transistors of the amplifier shorts) or HF oscillation be detected, the circuits disconnects the output by switching of a relay.

    Thanks in advance.

    There are MANY (if not all) with at least 2 ADC's on them..

    What you should be searching for is a PIC with ADC module(s). The 12F683, 16f877a, 18f4550, 18f2550,.............all have them.

    For plug and play interface between up to EIGHT analog inputs, and the USB input to your computer, there is no better device that a U-HID Nano Board from Ultimark.

    http://www.ultimarc.com/JShopServer/section.php?xSec=13

    Costing only $35 US, and totally eliminating all programming, I located this device with a search on this website, after failing to find anything comparable with a normal Google search.

    My home flight simulator twin-engine jet throttle quadrant is built around this board, and all 6 analog axes, as well as the two buttons for thrust reverse, work flawlessly when hooked up via a simple non-inverting signal-amplifier stage to the Nano Board, which is plugged into a standard USB port on the computer with the provided cable.

    I'll be posting details of this project when I wrap up the build and tidy it up. Use the Nano Board. It is dead simple to connect, and works like a charm.

    Thanks spinnaker and PaulEE. I was not aware of that. OK, I will look for PICs with ADC inputs. I don't know much about PICs, I must confess.

    Thanks, but I want to create my own solution by using a PIC.

    You need help - just give a holler. PICs are one of my (and many other people's) specialties.

    For example, I just got done designing a PIC to AD7718 (24-bit ADC) interface (posted on my facebook page), and last july - october I designed a device that timed the time-of-flight of ultrasonic pulses via remote-radio triggering. It was a good time! (both projects).

    :)
