AMC1301, low power consumption features

Mouser Electronics (www.mouser.com) is now stocking the AMC1301 reinforced isolation amplifier from Texas Instruments (TI). This device is the industry's first amplifier to withstand 1,000 VRMS breakdown voltage isolation with a minimum insulation life of 40 years.

The AMC1301, available from Mouser, is a high-reliability isolation amplifier featuring low power consumption, high DC accuracy, and improved overall power efficiency compared to existing devices. The amplifier maintains a low drift offset of 3µV/C over a wide operating temperature range of -40 to 125°C.

The AMC1301 device reduces high-voltage supply voltage by 65 percent and low-voltage supply voltage by 45 percent compared to similar products, improving overall power efficiency and simplifying power supply design, thereby reducing heat spread where high-efficiency system designs and improved performance are needed. The amplifier also offers nonlinearity accuracy of up to 0.04 percent and very low gain drift of 50 ppm per degree Celsius.


Mouser also offers the AMC1301EVM board for evaluating the AMC1301 device. This evaluation module includes four screw terminals for measuring the amplifier's analog inputs and outputs, and has a fixed gain of 8.2 and an input voltage range of ±250 mV, allowing input values to be optimized using shunt resistors.

The AMC1301EVM is a reference solution for measuring isolated current using a shunt resistor and the AMC130 amplifier. It is a high-precision evaluation board for measuring shunt-based current sensing in high-voltage applications such as industrial motor drives, solar inverters, battery management systems, and UPS.
