The ADE7763 features proprietary ADCs and fixed function DSP for high accuracy over large variations in environmental conditions and time. The ADE7763 incorporates two second-order, 16-bit ?-? ADCs, a digital integrator (on Ch1), reference circuitry, a temperature sensor, and all the signal processing required to perform active and apparent energy measurements, line-voltage period measurements, and rms calculation on the voltage and current channels. The selectable on-chip digital integrator provides direct interface to di/dt current sensors such as Rogowski coils, eliminating the need for an external analog integrator and resulting in excellent long-term stability and precise phase matching between the current and the voltage channels.The ADE7763 provides a serial interface to read data and a pulse output frequency (CF) that is proportional to the active power. Various system calibration features such as channel offset correction, phase calibration, and power calibration ensure high accuracy. The part also detects short duration, low or high voltage variations.The positive-only accumulation mode gives the option to accumulate energy only when positive power is detected. An internal no-load threshold ensures that the part does not exhibit any creep when there is no load. The zero-crossing output (ZX) produces a pulse that is synchronized to the zero-crossing point of the line voltage. This signal is used internally in the line cycle active and apparent energy accumulation modes, which enables faster calibration.The interrupt status register indicates the nature of the interrupt, and the interrupt enable register controls which event produces an output on the IRQ pin, an open-drain, active low logic output.The ADE7763 is available in a 20-lead SSOP package.

The?ADE7912/ADE7913 are isolated, 3-channel ?-? ADCs for a variety of applications such as shunt-based polyphase meters, power quality monitoring, solar inverters, process monitoring and protective devices. Data and power isolation are based on the Analog Devices, Inc., iCoupler? technology. The ADE7912 features two ADCs, and the ADE7913 features three ADCs. The current ADC provides a 67 dB signal-to-noise ratio over a 3 kHz signal bandwidth, whereas the voltage ADCs provide a SNR of 72 dB over the same bandwidth. One channel is dedicated to measuring thevoltage across a shunt when the shunt is used for current sensing.Up to two additional channels are dedicated to measuringvoltages, which are usually sensed using resistor dividers. Onevoltage channel can be used to measure the temperature of the dievia an internal sensor. The ADE7913 includes three channels:one current and two voltage channels. The ADE7912 has onevoltage channel but is otherwise identical to the ADE7913.??Applications Shunt based polyphase meters Power quality monitoring Solar inverters Process monitoring Protective devices Isolated sensor interfaces Industrial PLCs

Interfacing with both current transformer (CT) and Rogowski coil sensors, the ADE9078 enables users to develop a 3-phase metrology platform, which achieves high performance for Class 1 up to Class 0.2 meters.The ADE9078 integrates seven high performances ADCs and a flexible DSP core. An integrated high end reference ensures low drift over temperature with a combined drift of less than ?25 ppm/?C maximum per channel, each of which includes a programmable gain amplifier (PGA) and ADC.The ADE9078 offers an integrated flexible waveform buffer that stores samples at a fixed data rate or a sampling rate that varies based on line frequency to ensure 64 points per line cycle. These two options make it easy to implement harmonic analysis in an external processor according to IEC 61000-4-7.Two power modes are provided to enable detection of meter tampering: PSM2 uses a low power comparator to compare current channels to a threshold and indicates whether it is exceeded on the IRQ0 and IRQ1 outputs; PSM1 enables fast measurement of current and voltage rms (xVRMS and xIRMS), active power, and VAR during a tamper.The ADE9078 allows advanced and highly accurate energy measurements, enabling one platform to cover a wide range of meters, through a combination of various high end metrology features and superior analog performance.Applications Polyphase meters Power quality monitoring Protective device

The ADE9322B has highly accurate, 2-channel ?-? analog-to-digital converters (ADCs) with mSure? that converts two analog input signals into a single bit stream output. The device is enabled with an mSure sensor monitoring feature that allows the user to check the overall accuracy of the sensor and signal path to identify accuracy drifts that occur over time on the current and voltage channels, independently. The mSure sensor monitoring feature enables antitampering and meter health capabilities when incorporated into a larger system, including digital isolation, a digital metrology engine (ADE7979), and cloud analytics service. Self calibration with mSure enables the device to automatically calibrate the current and voltage channels to achieve a 1% energy accuracy.The ADE9322B incorporates high performance ADCs. The current channel is designed to interface with a shunt resistor. The voltage channel requires an input from a potential divider. A high speed serial peripheral interface (SPI) port and a universal asynchronous receiver and transmitter (UART) port allows access to the ADE9322B registers.Note that throughout the data sheet, multifunction pins, such as MISO/TX, are referred to either by the entire pin name or by a single function of the pin, for example, MISO, when only that function is relevant.The ADE9322B operates from a 3.3 V supply and is available in a 32-lead LFCSP.APPLICATIONS Shunt-based polyphase energy meters Solar inverters Process monitoring Smart power distribution units Polyphase ac chargers

The ADF4158 is a 6.1 GHz, fractional-N frequency synthesizer with modulation and waveform generation capability. It contains a 25-bit fixed modulus, allowing subhertz resolution at 6.1 GHz. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider.
