AD40xx Ease-of-Use Features
Analog Devices AD40xx family incorporates ease-of-use features that lower the signal chain power, reduce signal chain complexity, and enable higher channel density. The high-Z mode, along with a long acquisition phase, eliminates the requirement for a dedicated high-power, high-speed ADC driver. This expands the range of low-power precision amplifiers that can drive these ADCs directly while still achieving optimum performance.
The AD40xx input-span compression feature allows the ADC driver amplifier and the ADC to operate off common supply rails. The input-span compression feature does not need a negative supply and preserves the full ADC code range.
The low serial peripheral interface (SPI) clock rate reduces the digital input/output power consumption, broadens processor options, and simplifies the task of sending data across digital isolation.
