The is a high accuracy Analog Front End AFE for DC and AC energy measurement, offering high accuracy down to extremely low current typical of home appliances in stand-by. A full set of on-board features provides high system integration and enable on-chip power quality monitoring. The device has up to 4 independent 24 bits 2nd order ∑Δ ADC with PGA. The device has integrated DSP for "turn-key" energy parameters calculations. Built-in twin independently temperature compensated voltage references and double LED output programmable for active and reactive energy pulses generation.
