Analog Devices Energy Meter IC 64-Pin LQFP, ADE5569ASTZF62

The ADE5166, ADE5169, ADE5566 and ADE5569 from Analog Devices are single-phase energy measurement ICs. They combine an energy metering analogue front end and fixed function DSP solution with an enhanced 8052 MCU core and full real-time clock (RTC). In addition the device contains a LCD driver and appropriate peripherals, making these devices single chip solutions for electronic energy meters with an LCD display.
