A precision second-order sigma-delta modulator for energy metering applications that monitor shunt voltages and require galvanic.
SNR=80 dBFS, Uin ±25 mV, Ucc = 3.3V, DFN10 6.5x10 package.
The IC converts voltage drops across shunt-type current sensors into digital data. The on-chip digital isolation allows both sides of the system to operate at different common-mode voltages and protect the low-voltage part from hazardous damage.
Main application areas are energy meters, photovoltaic, EVs and charges, civil aviation and railway transportation.
