The ADE7752A is an accurate active energy measurement IC intended for use in any 3-phase distribution system. It provides instantaneous and average real power based on line current and voltage. The part specifications surpass the accuracy requirements as quoted in the IEC61036 standard. The only analog circuitry used in the ADE7752A is in the ADCs and reference circuit. All other signal processing (e.g., 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.Gain calibration between channels is adjusted external to this device. The ADE7752A is available in 24-lead SOIC package. The power consumption of ADE7752A is lower than ADE7752. ADE7752A is recommended for all new designs and may be used as a direct replacement for ADE7752. The parts are functionality and pin compatible.For additional technical information on your ADE7752A meter design, see AN-641: A 3-Phase Power Meter Based on the ADE7752 (pdf, 507,533 bytes).

This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9215 uses a multistage differential pipelined architecture with output error correction logic to provide 10-bit accuracy at 105 MSPS data rates and to guarantee no missing codes over the full operating temperature range.The wide bandwidth, truly differential sample-and-hold amplifier (SHA) allows for a variety of user-selectable input ranges and offsets including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available ADCs, the AD9215 is suitable for applications in communications, imaging, and medical ultrasound.A single-ended clock input is used to control all internal conversion cycles. A duty cycle stabilizer compensates for wide variations in the clock duty cycle while maintaining excellent performance. The digital output data is presented in straight binary or twos complement formats. An out-of-range signal indicates an overflow condition, which can be used with the MSB to determine low or high overflow.Fabricated on an advanced CMOS process, the AD9215 is available in both a 28-lead surface-mount plastic package and a 32-lead chip scale package and is specified over the industrial temperature range of −40°C to +85°C.PRODUCT HIGHLIGHTS The AD9215 operates from a single 3 V power supply and features a separate digital output driver supply to accommodate 2.5 V and 3.3 V logic families. Operating at 105 MSPS, the AD9215 core ADC consumes a low 120 mW; at 80 MSPS, the power dissipation is 104 mW; and at 65 MSPS, the power dissipation is 96 mW. The patented SHA input maintains excellent performance for input frequencies up to 200 MHz and can be configured for single-ended or differential operation. The AD9215 is part of several pin compatible 10-, 12-, and 14-bit low power ADCs. This allows a simplified upgrade from 10 bits to 12 bits for systems up to 80 MSPS. The clock duty cycle stabilizer maintains converter performance over a wide range of clock pulse widths. The out of range (OR) output bit indicates when the signal is beyond the selected input range.APPLICATIONS Ultrasound equipment IF sampling in communications receivers Battery-powered instruments Hand-held scopemeters Low cost digital oscilloscopes

A duty cycle stabilizer is provided to compensatefor variations in the ADC clock duty cycle, allowing theconverters to maintain excellent performance.The AD9600 has several functions that simplify the automatedgain control (AGC) function in a communications receiver. Forexample, the fast detect feature allows fast overrange detectionby outputting four bits of input level information with veryshort latency.In addition, the programmable threshold detector allows monitoringthe amplitude of the incoming signal with short latency,using the four fast detect bits of the ADC. If the input signal levelexceeds the programmable threshold, the fine upper thresholdindicator goes high. Because this threshold is set from the fourMSBs, the user can quickly adjust the system gain to avoid anoverrange condition.Another AGC-related function of the AD9600 is the signalmonitor. This block allows the user to monitor the compositemagnitude of the incoming signal, which aids in setting the gainto optimize the dynamic range of the overall system.The ADC output data can be routed directly to the two external10-bit output ports.
