1.2 Introduction

The AMC1333 is a 1-bit modulator with an output buffer separated from the input interface circuitry by a silicon dioxide (SiO2) isolation barrier. The isolation barrier provides galvanic isolation of up to 8000 VPEAK. When used in combination with a digital filter, the AMC1333 can be used to achieve 16-bit, analog-to-digital (A/D) conversion with no missing codes.

For use in high-resolution measurement applications, an effective accuracy of 14 bits can be obtained with a digital filter bandwidth of 20 kHz at a modulator rate of 10 MHz.
