EVALST-ISOSD61L

EVALST-ISOSD61L is a full-featured evaluation board designed to allow the user to evaluate all the features of the ISOSD61L isolated analogue-to-digital converter (ADC). The ISOSD61L 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 ISOSD61L device can be used to achieve 16-bit analogue-to-digital (A/D) conversion with no missing codes.
