TI isolated amplifier, modulator enable high-precision current measurement in motor control, green energy applications

DALLAS July 13, 2011

The AMC1200 is a 4-kV peak isolated amplifier providing 80-percent better linearity and gain drift compared to competitive devices while reducing power consumption by 50 percent. The AMC1204 is a 20-MHz, externally-clocked, isolated delta-sigma modulator that provides 40-percent better linearity than the competition.

Key features and benefits

    • High precision with a maximum non-linearity of 0.07 percent and gain drift of 56 ppm/C.
    • Reduced power consumption with a low high-side supply current of no more than 8 mA at 5 V.
    • Fully specified over the extended industrial temperature range of -40 to 105 degrees C – 20 degrees higher than competitive offerings.
    • analog-to-digital converters microcontrollers
    • Ultra-high accuracy with best-in-class non-linearity of +/- 8 LSB, maximum, and a digital output that allows designers to define digital filter characteristics based on system requirements.
    • Includes an external clock interface to enable simultaneous measurement of multiple channels.
  • UL 1577 IEC 60747-5-2 CSA
