ADC121C021 best choice for this?

Other Parts Discussed in Thread: ADC121C021

Hi,


I'm considering the ADC121C021 for a design, and was wondering if there were other options acailable that might be better suited.


I'm going to use it to read the output of a charge integration amplifier circuit, and would like to configure it so that it runs in automatic mode.  What a packet of charge comes through the amplifier (as a voltage pulse), and is read by the A2D, I plan to have the ALERT pin signal an interrupt, and then read the highest conversion register until it is stable to get the max pulse height.  Then I reset the register and wait for the next one. 


Are there any other A2Ds that offer the same features (Alert, automatic mode, highest conversion register), but are considered more "precision" devices?  12 Bits should be enough, but if I can go higher and have a device with better noise performance, I'd prefer that.

Thanks

  • Adam,

    It might help if you could elaborate more on what you need. It might be helpful to know what data rate and noise performance you want to measure your system. Other information that would be helpful would be the supply voltage and the method of communication that you want to use.


    The more information you give would help differentiate the devices that would best suit your needs.
