PROBLEM CHOOSING APPROPRIATE ADC

DEVI VARAPRASAD REDDY JONNALA
Prodigy 10 points

I have to implement a system which calculates the power dissipated due to discharge by a high voltage power supply. For that I need a micro-controller(or an ADC as such) which has ADC with conversion time between 1-10 ns. The reason for my choice is that, there will be spikes in the current which last only for maximum period of 10ns. we have to measure them accurately. FIrst I though of MSP430G2xx but it has adc with conversion time around 3micro seconds. Please help with the ADC with least possible conversion time.

Thanks

    Hi Devi,

    I have a few questions to help in the ADC selection process.

    - Bit resolution (8 bit, 12 bit, 16 bit...)
    - Output Interface (SPI?)
    - How many ADC channels are required?
    - How high of a voltage is being sampled?
    - DC coupled? Amplifier input?

    Best Regards,

    Dan
