Texas Instruments has introduced a reinforced isolated amplifier with the highest reliability, lowest power consumption, highest DC accuracy and improved overall efficiency compared to competitive devices. The AMC1301 delivers the most accurate solution for shunt-based current sensing in high-voltage applications, such as industrial motor drives, solar inverters, battery management systems and UPS.
With the lowest offset error maximum of 200µV, the lowest offset drift of 3µV/C and the best linearity of 0.03%, the AMC1301 enables engineers to design the most accurate system using an isolated amplifier over the widest temperature range, from -40 to +125°C, without having to compensate for DC and temperature drift errors.
The AMC1301 is the industry's first isolated amplifier with a working breakdown voltage of 1,000Vrms for a minimum insulation barrier lifetime of 64 years, which exceeds VDE0884-10 requirements. Like all of the isolated devices in TI's portfolio, the AMC1301 has no relevant lifetime degradation, unlike optical components.
At 55% less high-side supply current and 45% less low-side supply current than competitive devices, the isolated amplifier improves power efficiency, simplifies power supply design and reduces thermal drift issues for a more efficient system design and improved performance.
The AMC1301 is available in a 5.85x7.5mm SOIC package for $2.90 in 1,000 unit quantities.
