This tutorial is all about intelligent transmitters with high-resolution low-power D/A converters employed within their system. Transducers with 4-20 mA current loop are also particularly cited on a ...

Analog Devices has designed a high-resolution data acquisition chip for 4-20mA current loops around an ARM Cortex-M3 core. Called ADuCM360, the chip includes dual 4ksample/s 24-bit sigma-delta DACs ...

Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...
