ADE7755 is a power metering IC produced by Analog Devices. It has high accuracy, high dynamic range and multiple output functions. It is widely used in power metering, electric vehicle charging and other fields.
The ADE7755 is a high accuracy electrical energy measurement IC designed to surpass the accuracy requirements of IEC 1036 standards. It utilizes proprietary ADCs and DSPs to ensure superior stability and accuracy over variations in environmental conditions and time. The device supplies average active power information on low frequency outputs (F1 and F2) and instantaneous active power on a high frequency output (CF), suitable for driving electromechanical counters or interfacing with microcontrollers.
The IC features a programmable gain amplifier in the current channel, allowing the use of small shunts and burden resistors. It includes on-chip power supply monitoring, creep protection, and a stable 2.5V reference. The ADE7755 is available in a 24-lead SSOP package and operates on a single 5V supply with low power consumption.
