AD4002/AD4006/AD4010 Data Sheet
FEATURES analog-to-digital converters (ADCs). The AD4002, AD4006,
and AD4010 offer 2 MSPS, 1 MSPS, and 500 kSPS throughputs,
respectively. They incorporate ease of use features that reduce
signal chain power consumption, reduce signal chain complexity,
and enable higher channel density. The high-Z mode, coupled with
a long acquisition phase, eliminates the need for a dedicated high
power, high speed ADC driver, thus broadening the range of
low power precision amplifiers that can drive these ADCs directly
while still achieving optimum performance. The input span compression feature enables the ADC driver amplifier and the ADC
to operate off common supply rails without the need for a negative
supply while preserving the full ADC code range. The low serial
peripheral interface (SPI) clock rate requirement reduces the digital
input/output power consumption, broadens processor options,
and simplifies the task of sending data across digital isolation. Throughput: 2 MSPS/1 MSPS/500 kSPS options
