I am seeking an ultralow power ADC. The data sheet for the AD7988-1 indicates an energy comsumption spec of 7nJ/conversion - is there a range of sample rates for which this is valid, or does it apply for any sample speed?
AD7988-1
Production
The AD7988-1/AD7988-5 are 16-bit, successive approximation,
analog-to-digital converters (ADC) that operate from a single
power supply, VDD. The AD7988...

Hi Peter,
The power for the AD7988 is related and varies linearly with throughput. The power consumption of the AD7988 can be derive by simply multiplying energy per conversion with the sample rate.
