What ADC to use with Cam 2a for interfacing with Propeller?

Hello, Component question. I want to interface a CAM2a camera with a propeller via an ADC chip. Hanno suggests using TLC 5540. I was wandering whether the ADC0804 (which I can get from Rapid Electronics www.rapidonline.com/Electronic-Components/Integrated-Circuits/Converters/Analogue-to-digital-converters/34429/kw/adc ) would work as I can not find a TLC 5540 in a DIL package inside the UK

    Hi Eric,
    Even better than the TLC 5540 is the ADC 08100. See here for datasheet
    It's low voltage (3V), so it can be clocked straight from the Propeller (unlike the TLC5540). It also comes in versions up to 100msps!
    It's a tssop which isn't too hard to solder. Here's a schematic for hooking the cam2 up to the propeller:

    You made me curious. What's a CAM2a?

    I bought a couple ccam2a from electronics123.com last year for $10 each. Unfortunately they're out of stock there now... They do carry a model with the same sensor that includes a nice housing, audio input, high ir sensitivity, and a light- all for $16.15 each. Only 8 left! (It does seem to require 9-12v)

    The last video on my video page shows how I use ViewPort to get my Dancebot to follow a line using this camera.
    I used this camera/sensor because it was tiny, cheap, and outputs a monochrome ntsc signal which ViewPort's VideoCapture object can grab.

    They currently have C-Cam2AX for $18.50. is this the same? I hope so because I ordered one.

    Look at this page. The link to the data sheet points to the data sheet of C-Cam2A.

    Uh-oh, I shouldn't have told you. They will be sold out when I'll order one... smilewinkgrin.gif

    I know this thread is kind of old, but I was wondering if anyone has had luck getting this setup going with their prop? I am wondering about a couple of things as far as the wiring goes.

    I have mine working, however the camera resolution is very low quailty, not even useable.

    Thanks

    Hanno or Eric, please can you help me?
    Is there anywhere in UK (or even europe) i can buy this ADC 08100 chip?

    Thank you.

    I got this information off of the National site.
