Enhance accuracy, reliability and cost-effectiveness with high-performance galvanic isolated ADCs.
Isolated analog-to-digital converters (ADCs) are second-order sigma-delta modulators that convert analog values into a 1-bit stream and are able to withstand high common-mode voltages. Combining high-speed with ultra-low power dissipation, our isolated ACDs provide a very efficient signal-to-noise ratio resulting in a highly cost-effective integration that lets you reduce bill of material costs. The isolation grade and the high accuracy class are key to reliably sensing currents and voltages to ensure the robustness and high performance of many industrial applications.
Available with either a TTL (ISOSD61T) or LVDS (ISOSD61L) input, these 1-bit sigma-delta modulators have an output buffer separated from the input interface circuitry by a galvanically isolated barrier providing protection up to 6000 VPEAK.
When used in combination with a digital filter, the ISOSD61 can be used for 16-bit analog-to-digital (A/D) conversion with no missing code. Full-featured evaluation boards designed to let you explore all the features of the ISOSD61 isolated analog-to-digital converters (ADC) are also available.
ST's high performance converters combine high-speed with ultra-low power consumption by using 0.25µm and 130nm high-end proven technology in high volume.
Designed using ST’s radiation-hardening architecture and layout rules, ST’s ADC and DAC meet the most stringent radiation immunity standards and qualification criteria to fit with applications in Satellites.
