ADE7755ARSZ-RL - Brand New Analog Devices Energy Metering
-
Description
The ADE7755ARSZ-RL is a high accuracy electrical energy measurement IC in the field of energy metering. It is designed to surpass the accuracy requirements set by the IEC 1036 standard. Unlike other similar components, the ADE7755ARSZ-RL uses only analog circuitry in the ADCs and reference circuit, with all other signal processing being carried out digitally. This approach provides superior stability and accuracy in various environmental conditions and over time. The ADE7755ARSZ-RL offers average active power information through its low frequency outputs (F1 and F2), which can be used to drive electromechanical counters or interface with an MCU. Additionally, it provides instantaneous active power information through its CF logic output, which is mainly intended for calibration purposes or MCU interfacing.
Specifications and features
- High accuracy, surpassing the 50 Hz/60 Hz IEC 687/IEC 1036 standards
- Error rate of less than 0.1% over a dynamic range of 500 to 1
- Supplies active power on the low frequency outputs, F1 and F2
- High frequency output CF for calibration and instantaneous active power
- Synchronous CF and F1/F2 outputs
- Logic output REVP provides active power sign information
- Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2)
- Programmable gain amplifier (PGA) facilitates the usage of small shunts and burden resistors in the current channel
- Proprietary ADCs and DSPs ensure high accuracy across varying environmental conditions and time
- On-chip power supply monitoring
- On-chip creep protection (no load threshold)
- On-chip reference 2.5 V ± 8% (30 ppm/°C typical) with external overdrive capability
- Designed for a single 5 V supply and low power consumption (15 mW typical)
- Manufactured using low-cost CMOS process
Application Scenarios
The ADE7755ARSZ-RL can be widely used in energy metering applications where high accuracy and stability are crucial. It is particularly suitable for applications that require precise measurement of electrical energy usage, such as smart grid systems, industrial energy monitoring, and energy management systems.
