Driving a Low Noise, Low Distortion 18-Bit, 1.6Msps ADC Design Note 494
The document provides design guidance for driving the LTC2379-18, an 18-bit, 1.6Msps SAR ADC with high SNR and THD. It presents two specific circuit solutions: a fully differential driver using the LT6203 to convert ±5V signals to 0V to 5V, and a single supply driver using the LTC6350 and digital gain compression for ±10V inputs.

Questions answered in these manuals
What is the full-scale input swing for a single supply driver using a 5V reference?
The full-scale input swing is defined as 10% to 90% of the reference voltage, which results in a range of 0.5V to 4.5V.
