The AD5124 / AD5144 / AD5144A potentiometers provide a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the Ax, Bx, and Wx pins.The low resistor tolerance and low nominal temperature coefficientsimplify open-loop applications as well as applications requiringtolerance matching.The linear gain setting mode allows independent programmingof the resistance between the digital potentiometer terminals, through the RAW and RWB string resistors, allowing very accurate resistor matching.The high bandwidth and low total harmonic distortion (THD)ensure optimal performance for ac signals, making these devicessuitable for filter design.The low wiper resistance of only 40 Ω at the ends of the resistor array allow for pin-to-pin connection.The wiper values can be set through an SPI-/I2C-compatible digital interface that is also used to read back the wiper register andEEPROM contents.The AD5124 / AD5144 / AD5144A are available in a compact, 24-lead, 4 mm × 4 mm LFCSP and a 20-lead TSSOP. The partsare guaranteed to operate over the extended industrial temperaturerange of −40°C to +125°C.APPLICATIONS Portable electronics level adjustment LCD panel brightness and contrast controls Programmable filters, delays, and time constants Programmable power supplies

The ADE9000 is a highly accurate, fully integrated, multiphase energy and power quality monitoring device. Superior analog performance and a digital signal processing (DSP) core enable accurate energy monitoring over a wide dynamic range. An integrated high end reference ensures low drift over temperature with a combined drift of less than ±25 ppm/°C maximum for the entire channel including a programmable gain amplifier (PGA) and an analog-to-digital converter (ADC).The ADE9000 offers complete power monitoring capability by providing total as well as fundamental measurements on rms, active, reactive, and apparent powers and energies. Advanced features such as dip and swell monitoring, frequency, phase angle, voltage total harmonic distortion (VTHD), current total harmonic distortion (ITHD), and power factor measurements enable implementation of power quality measurements. The ½ cycle rms and 10 cycle rms/12 cycle rms, calculated according to IEC 61000-4-30 Class S, provide instantaneous rms measurements for real-time monitoring.The ADE9000 offers an integrated flexible waveform buffer that stores samples at a fixed data rate of 32 kSPS or 8 kSPS, or a sampling rate that varies based on line frequency to ensure 128 points per line cycle. Resampling simplifies fast Fourier transform (FFT) calculation of at least 50 harmonics in an external processor.The ADE9000 simplifies the implementation of energy and power quality monitoring systems by providing tight integration of acquisition and calculation engines. The integrated ADCs and DSP engine calculate various parameters and provide data through user accessible registers or indicate events through interrupt pins. With seven dedicated ADC channels, the ADE9000 can be used on a 3-phase system or up to three single-phase systems. It supports current transformers (CTs) or Rogowski coils for current measurements. A digital integrator eliminates a discrete integrator required for Rogowski coils.The ADE9000 absorbs most complexity in calculations for a power monitoring system. With a simple host microcontroller, the ADE9000 enables the design of standalone monitoring or protection systems, or low cost nodes uploading data into the cloud.Note that throughout this data sheet, multifunction pins, such as CF4/EVENT/DREADY, are referred to either by the entire pin name or by a single function of the pin, for example, EVENT, when only that function is relevant.Applications Energy and power monitoring Power quality monitoring Protective devices Machine health Smart power distribution units Polyphase energy meters
