Providing new levels of performance and longer lifespan in high-voltage motor drives and power inverters

TI (CEO Kent Tran) announced the release of an enhanced isolation amplifier that provides the best reliability, lowest power consumption, highest DC accuracy, and overall improved efficiency compared to competing devices.

The new AMC1301, featuring industry-leading operating voltage specifications, is the latest addition to TI's reinforced isolation portfolio. Additionally, with the lowest offset drift characteristics of 3uV/C over the widest temperature range of -40C to 125C, the AMC1301 provides the most accurate solution for shunt-based current sensing in high-voltage equipment such as industrial motor drives, solar inverters, battery management systems, and uninterruptible power supplies.

The AMC1301 is the industry's first isolation amplifier to provide an isolation barrier life of at least 64 years, providing an isolation voltage of 1,000 Vrms and meeting VDE0884-10 requirements. Like all isolated devices in the TI portfolio, the AMC1301 does not experience performance degradation over time, unlike optical components.

This isolation amplifier provides 55% lower high-side supply current and 45% lower low-side supply current than competing devices, thereby improving power efficiency, simplifying power supply design, and reducing thermal drift issues, enabling more efficient system design and improved performance.

The AMC1301, which provides a minimum offset error of up to 200uV, minimum offset drift, and maximum linearity of 0.03%, allows developers to design the most accurate systems using isolated amplifiers over the widest temperature range without the need to compensate for DC and temperature drift errors.
