Hi. Does anyone know an ADC I could use for a voltmeter module. Looking for a fairly cheap one. Don't know models. Need it to measure voltages up to 12 volts.
It has 12 bits resolution which will detect changes of 0.0029V and it has a serial output. You can find a new one from other suppliers like DigiKey, RS etc.
Also I need it to have a very high sampling frequency because I will need it to sample a signal which could be potentially as high as 50khz. therefore will need it to sample at least at 25khz. Is something like that availabe??
