AMC1204EVM

全功能评估板 Full-featured evaluation module

The is an evaluation module for AMC1204, a one 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 4000VPEAK. When used in combination with the AMC1210 or other digital filter, the AMC1204 can be used to achieve 16bit analog to digital A/D conversion with no missing codes. For use in high resolution measurement applications, an effective accuracy of 14bits can be obtained with a digital filter bandwidth of 20kHz at a modulator rate of 10MHz. The evaluation module is a small form factor board containing all the necessary components to evaluate the AMC1204 device.
