ADE5166/ADE5169/ADE5566/ADE5569
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: 4.4 mA to 1.6 mA (PLL clock dependent) Battery mode: 3.3 mA to 400 µA (PLL clock dependent) Sleep mode
Real-time clock (RTC) mode: 1.7 µA RTC and LCD mode: 38 µA (LCD charge pump enabled) Reference: 1.2 V ± 0.1% (10 ppm/°C drift) 64-lead, low profile quad flat, RoHS-compliant 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 (volt-ampere (VA)) measurement <0.1% error on active energy over a dynamic range of 1000 to 1 @ 25°C <0.5% error on reactive energy over a dynamic range of 1000 to 1 @ 25°C (ADE5169 and ADE5569 only) <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 (ADE5169 and ADE5569 only)
2 current inputs for antitamper detection in the ADE5166/ ADE5169
High frequency outputs proportional to Irms, active, reactive, or apparent power (AP)
