APPLICATION NOTE 3408
DS1856 Internal Calibration and Right Shifting (Scalable Dynamic
Ranging)

Abstract: This application note explains the internal calibration procedure for the DS1856, and how using this
function can be beneficial to the application. The application note also provides procedures for determining and
implementing the internal calibration and right-shifting features of the DS1856.


Introduction

The DS1856 uses internal calibration and right shifting (Scalable Dynamic Ranging) to enhance the built-in 12-
bit ADC. This gives the DS1856 the precision and accuracy of a 16-bit ADC with
