DALLAS, USA: Texas Instruments Inc. (TI) has introduced an isolated amplifier and a delta-sigma modulator that enable best-in-class shunt-based current measurement in motor control and green energy applications.
The AMC1200 isolated amplifier and AMC1204 delta-sigma modulator allow designers to increase accuracy, temperature stability and immunity to magnetic fields in equipment such as AC drives, solar inverters and uninterruptible power supplies.
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.
