APPLICATION NOTE 167
Considerations for the DS1847/DS1848 Look-Up Tables

Abstract: This application note covers the use of look-up tables in the control of laser bias and modulation. The tables are a part of a feedforward control based on temperature
which varies the value of the controlling signal as temperature changes.


Introduction

The DS1847 and DS1848 are digitally controlled resistors. The look-up tables in these parts are used to store Resistor positions that discretely compensate for the user’s application
temperature de……
