ADE7753 is a single-phase multifunctional metering IC with di/dt sensor interface from Analog Devices. It features high accuracy, supports IEC 60687/61036/61268 and IEC 62053-21/62053-22/62053-23 standards, on-chip digital integrator enables direct interface to current sensors with di/dt output, supports active, reactive, and apparent energy, sampled waveform, current and voltage rms, etc.
The ADE7753 integrates two 16‑bit ADCs, a digital integrator, on‑chip reference, temperature sensor and full signal‑processing chain to measure active, reactive and apparent energy, line‑voltage period and RMS values. It supports direct connection to di/dt current sensors such as Rogowski coils, eliminating the need for external analog integrators.
The device operates from a single 5 V supply (±5 %), offers programmable thresholds for voltage sag and surge, a pulse output proportional to active power, and an interrupt request pin. It is supplied in a 20‑lead SSOP package and meets IEC 60687/61036/61268 and IEC 62053‑21/22/23 standards.
