Evaluation board for ISOSD61 isolated sigma-delta converter

The EVALST-ISOSD61T is a full-featured evaluation board designed to allow the user to evaluate all the features of the ISOSD61 isolated analog-to-digital converter (ADC).

The ISOSD61 device is a 1-bit sigma-delta modulator with an output buffer separated from the input interface circuitry by a galvanic isolation barrier. The isolation barrier provides galvanic isolation of up to 6000 VPEAK. When used in combination with a digital filter, the ISOSD61 device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing codes.
