Introduction
The AMC1204 is a 1-bit modulator with an output buffer separated from the input interface circuitry by a
silicon dioxide (SiO 2 ) isolation barrier. The isolation barrier provides galvanic isolation of up to 4000 V PEAK .
When used in combination with the AMC1210 or other digital filter, the AMC1204 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.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the AMC1204EVM.
Analog Interface
The analog input to the AMC1204 is routed from a two-wire screw terminal screw at J4. This screw
terminal gives the user access to the inverting and noninverting inputs of the AMC1204.
Analog Inputs
The analog input to the AMC1204EVM board consists of simple R/C filter circuits. The input circuit for the
