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
