The ADE7761B is a high accuracy, fault-tolerant, electrical energy measurement IC intended for use with 2-wire distribution systems. The part specifications surpass the accuracy requirements as quoted in the IEC 62053-21 standard. The only analog circuitry used on the ADE7761B is in the ADCs and reference circuit. All other signal processing (such as multiplication and filtering) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time. The ADE7761B incorporates a fault detection scheme similar to the ADE7751 by continuously monitoring both phase and neutral currents. A fault is indicated when the currents differ by more than 6.25%.The ADE7761B incorporates a missing neutral detection scheme by continuously monitoring the input voltage. When a missing neutral condition is detected (no voltage input), the ADE7761B continues billing based on the active current signal (see the Missing Neutral Mode section). The missing neutral condition is indicated when the FAULT pin goes high. The ADE7761B supplies average active power information on the low frequency outputs, F1 and F2. The CF logic output gives instantaneous active power information.The ADE7761B includes a power supply monitoring circuit on the VDD supply pin. Internal phase matching circuitry ensures that the voltage and current channels are matched. An internal no-load threshold ensures that the ADE7761B does not exhibit any creep when there is no load.

The AD7357 is a dual, 14-bit, high speed, low power, successive approximation ADC that operates from a single 2.5 V power supply and features throughput rates of up to 4.2 MSPS. The part contains two ADCs, each preceded by a low noise, wide bandwidth track-and-hold circuit that can handle input frequencies in excess of 110 MHz.The conversion process and data acquisition use standard control inputs allowing for easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS; conversion is also initiated at this point. The conversion time is determined by the SCLK frequency.The AD7357 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With a 2.5 V supply and a 4.2 MSPS throughput rate, the device consumes 14 mA typically. The part also offers flexible power/throughput rate management when operating in normal mode as the quiescent current consumption is so low.The analog input range for the device is the differential common mode ±VREF/2. The AD7357 has an on-chip 2.048 V reference that can be overdriven when an external reference is preferred.The AD7357 is available in a 16-lead thin shrink small outline package (TSSOP) and an 18-lead lead frame chip scale package (LFCSP).PRODUCT HIGHLIGHTS Two Complete ADC Functions. These functions allow simultaneous sampling and conversion of two channels. The conversion result of both channels is simultaneously available on separate data lines or in succession on one data line if only one serial port is available. High Throughput with Low Power Consumption.  The AD7357 offers a 4.2 MSPS throughput rate with 36 mW power consumption. Simultaneous Sampling. The part features two standard successive approximation ADCs with accurate control of the sampling instant via a CS input and once off conversion control.APPLICATIONS Automotive radar Data acquisition systems Motion control I and Q demodulation RFID readers

On power-down, the current state of the parameters can be written back to the EEPROM from the ADAU1701 to be recalled the next time the program is run.Two Σ-Δ ADCs and four Σ-Δ DACs provide a 98.5 dB analog input to analog output dynamic. Each ADC has a THD + N of −83 dB, and each DAC has a THD + N of −90 dB. Digital input and output ports allow a glueless connection to additional ADCs and DACs. The ADAU1701 communicates through an I2C® bus or a 4-wire SPI port.APPLICATIONS Multimedia speaker systems MP3 player speaker docks Automotive head units Minicomponent stereos Digital televisions Studio monitors Speaker crossovers Musical instrument effects processors In-seat sound systems (aircraft/motor coaches)

The AD8313 is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its input to an equivalent decibel-scaled value at its dc output. The AD8313 maintains a high degree of log conformance for signal frequencies from 0.1 GHz to 2.5 GHz.
