Texas Instruments introduces AMC1301reinforced isolated amplifier

Texas Instruments (TI) has introduced a reinforced isolated amplifier- AMC1301. According to the company AMC1301 comes with Industry’s highest reliability, lowest power consumption, highest DC accuracy and improved overall efficiency compared to competitive devices.

The AMC1301 with the lowest offset drift of 3 uV/C over the widest temperature range, -40C to 125C, the AMC1301 promises to deliver 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.

Key features of TI AMC1301

  • AMC1301 is the company’s first isolated amplifier with a working breakdown voltage of 1,000 Vrms 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 percent less high-side supply current and 45 percent 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.
  • With lowest offset error maximum of 200 uV, the lowest offset drift and linearity of 0.03 percent, the AMC1301 enables engineers to design accurate system using an isolated amplifier over the widest temperature range, without having to compensate for DC and temperature drift errors.
