Description
The ADE7932ARIZ is a 3-channel, isolated, sigma-delta (Σ-Δ) ADC designed for energy metering and power monitoring applications. It integrates three high-resolution ADCs (two for current sensing, one for voltage sensing) with isolated serial interfaces (SPI/I²C), ensuring robust performance in high-voltage environments.
Key features:
- 16-/24-bit resolution ADCs with >90dB SNR
- 5kV RMS isolation (enhanced safety)
- On-chip temperature sensor and reference
- Low power consumption (<10mW)
- Supports shunt or current transformer (CT) sensors
Ideal for smart meters, industrial monitoring, and grid infrastructure, the ADE7932ARIZ simplifies design while meeting IEC 62053/ANSI C12.20 standards. Its isolation and high accuracy make it suitable for AC/DC power measurement in harsh environments.
Package: 20-lead SOIC (RoHS-compliant).
