Single-Phase Energy Measurement IC with
8052 MCU, RTC, and LCD Driver
ADE7566/ADE7569/ADE7166/ADE7169
GENERAL FEATURES
Wide supply voltage operation: 2.4 V to 3.7 V
Internal bipolar switch between regulated and battery inputs
Ultralow power operation with power-saving modes (PSM)
Full operation: 4 mA to 1.6 mA (PLL clock dependent)
Battery mode: 3.2 mA to 400 μA (PLL clock dependent)
Sleep mode
www.DataSheet4U.cRoemal-time clock (RTC) mode: 1.5 μA
RTC and LCD mode: 27 μA (LCD charge pump enabled)
Reference: 1.2 V ± 0.1% (10 ppm/°C drift)
64-lead RoHS package options
Lead frame chip scale package (LFCSP)
Low profile quad flat package (LQFP)
Operating temperature range: −40°C to +85°C
ENERGY MEASUREMENT FEATURES
Proprietary analog-to-digital converters (ADCs) and digital
signal processing (DSP) provide high accuracy active
(Watt), reactive (VAR), and apparent energy (VA)
measurement
Less than 0.1% error on active energy over a dynamic
range of 1000 to 1 @ 25°C
Less than 0.5% error on reactive energy over a dynamic
range of 1000 to 1 @ 25°C (ADE7569 and ADE7169 only)
Less than 0.5% error on root mean square (rms)
measurements over a dynamic range of 500 to 1 for
current (Irms) and 100 to 1 for voltage (Vrms) @ 25°C
Supports IEC 62053-21, IEC 62053-22, IEC 62053-23,
EN 50470-3 Class A, Class B, and Class C, and ANSI C12-16
Differential input with programmable gain amplifiers (PGAs)
supports shunts, current transformers, and di/dt current
sensors (ADE7569 and ADE7169 only)
Two current inputs for antitamper detection in the
ADE7166/ADE7169
High frequency outputs proportional to Irms, active, reactive,
or apparent power (AP)
