Introduction
It is now possible to place large RC networks directly in front of high resolution ΔΣ analog-to-digital converters without degrading their DC accuracy (see Figure 338.1). The LTC248x family of converters solves this problem with Easy Drive technology, a fully passive sampling network that automatically cancels the differential input current. Easy Drive technology does not use on-chip buffers, which compromise performance (see ...
