ADE7169ASTZF16

The ADE7169ASTZF16 from Analog Devices is a sophisticated single-phase energy measurement integrated circuit. It features an embedded 8052-based microcontroller core, a real-time clock (RTC), and an LCD driver, making it suitable for advanced energy monitoring applications.

This IC provides high-accuracy measurements for active (watt), reactive (var), and apparent energy (volt-ampere). It boasts a low active energy error of less than 0.1% over a dynamic range of 1000:1 at 25°C. The device supports various industry standards including IEC 62053-21, IEC 62053-22, IEC 62053-23, EN 50470-3, and ANSI C12-16.

Designed for wide supply voltage operation from 2.4 V to 3.7 V, the ADE7169ASTZF16 operates within a temperature range of -40°C to +85°C. It is available in a 64-lead LQFP package, suitable for surface mounting. The device also includes ultralow power operation modes, with specific current consumption figures for full operation, battery mode, sleep mode, and RTC/LCD mode.

Key features include proprietary ADCs and DSP for precise energy calculation, a 1.2 V ±0.1% reference with low drift, and multiple wake-up sources for efficient power management. The integrated 8052 MCU provides a 4 MIPS core with an 8052-compatible instruction set, supporting external crystal operation and interrupt sources.
