AD7768 FAQ - What front end driver amplifier is suitable to drive the AD7768?

There are many amplifiers suitable to drive the AD7768/AD7768-4. Choosing the most suitable amp can be a difficult task, especially when there are constraints on the system power. In order to achieve the lowest power and highest accuracy in a data acquisition (DAQ) system the following application note can be used as a starting point to select the most suitable driver amplifier:

Modular Data Acquisition (DAQ) Footprint Using the AD7768/AD7768-4 

This application note outlines how to achieve −126.6 dB of total harmonic distortion (THD) at subsystem power levels as low as 19.5 mW per channel.

The driver amplifier and RC filter combinations recommended in this document apply to the AD7768, AD7768-4, and also to the AD7768-1New which is single-channel version of the same AD7768 family.Updated
