Touchstone semi sent us two TS-9001 analog comparator+reference evaluation boards to give away. Leave a comment on this post if you want one, and we’ll give them away on Thursday. Mention how you might use this part for bonus points.
The demo board contains two TS9001s – the push-pull TS9001-1 and the open-drain TS9001-2 – where each circuit is configured as a simple threshold detector with additional hysteresis.
If you are really interested in a demo board, they might send you a sample too.

I would be interested in receiving one of these. Thanks for the great website!
Hello, I would like to receive one too, thanks!
Chances are less, but if I win somehow, I’ll try to implement a Voltage monitor type system with this one.
Plan simple: TS9001+ATtiny+Attiny+LCD
I want to make a DIY user interface for my power source.
TS9001+PIC18F+GLCD
Won’t GLCD be a costly solution?
i have already the GLCD from a scrap yard
I would very much like one of these. I am experimenting with voltage-mode feedback loops in switched-mode power supplies so having a board like this could be useful for generating a PWM switching signal.
I’d like one of those.
I’m going to unsolder the crap op-amps and use the board as a breakout for something else.
I’m interested in one of these. Thanks!
I’ll use these to make a handheld version of a ‘Open Source Brain Computer Interface Device’ I’m working on.
Thank you Dangerous Prototypes! We will send free evaluation boards to the next 10 people that request them. Just go to http://www.touchstonesemi.com/freesamples.html and ask for a TS9001 EV-Board or a TS1001 EV-Board!

I wonder if these op-amps would work for the arduino sound localization sensor project?
Dont think so. The GBW is 4KHz. The audio would be distorted by the time you sample the audio using the Arduino ADC.Will be better off with a Audio OpAmp. That is also why they dont want to publish their distortion specs as they are not cut out for Audio.
Good luck!
i would like one to play with.
I would like one of these to use with my Netduino that I am learning.
ultrasounder:
That may be so. But I could still use them to tinker. I haven’t don’t anything with op-amps for a while. I can always de-solder those and replace them with a part more appropriate for my intended use.
who WOULDN’T want an op-amp demo board!?!
Oh Pick me!!! I could definitely use them for my radio project. I need to tryout some of these. Thanks guys!
This looks like a great board to experiment with. I am currently looking at sensing light intensity so these might be a contender
Yes please! I’d like to use it to amplify voltage from a DIY hall sensor.
I’d like one of those.
should be interesting
I think I’ve gathered enough courage to start with analog electronics, and this should be of great help!
I would like one of those! This is exactly what I need to make my graphical On-screen-display. Right now I have to use a normal comparator and a resistor divide “reference”.
I’m game! I’ll take one. Thanks!!
I’d certainly like to try one out, count me in!
Can I have one please?
TS-9001 analog comparator+reference evaluation boards give away
Are these still available?
This was more than a year ago so I doubt it.
