I'd like to build a very simple voltage comparator circuit with the following properties:
- Vs = 5V
- V- = Ground
- Vout = 5V if V+ >= 200mV
- Vout = 0V if V+ < 200mV
I'm using this comparator: NTE943M
Any help is greatly appreciated.
The NTE934M is a copy of the LM393. Its outputs are 'open collector' and can only pull down. You need a pullup resistor (the datasheet suggests 1.5K).
