Texas Instruments (TI) introduced digital isolation and delta-sigma modulator families that offer reinforced isolation to help protect electronic equipment from high line voltages. The ISO7842 family provides the industry's highest immunity reinforced isolators and the first to withstand an isolation barrier with a working breakdown voltage of 1,500 Vrms for a minimum lifetime of 40 years. The AMC1304 delta-sigma modulator family offers best-in-class precision performance and the lowest power consumption with reinforced isolation for current shunt monitoring.
Manufacturers of factory automation, motor control and other industrial equipment are integrating more advanced electronics to reduce power and increase efficiency and system intelligence, driving data rate requirements higher and raising the bar on system performance.
TI's new devices offer robust, high-speed, high-performance reinforced isolation to meet critical functional and safety isolation requirements for applications exposed to potential high voltage breakdowns, while providing decades of reliability with precision analog performance and high immunity for noisy industrial environments.
The four-channel ISO7842 is the first in a reinforced digital isolator family that will include quad-, triple-, dual- and single-channel devices. The AMC1304M25 with integrated LDO and CMOS interface and AMC1305L25 delta-sigma modulators are the first of seven devices, which will support inputs ranging from +/-50 to +/-250 mV.
