The AD7895 is a fast 12-bit ADC that operates from a single +5 V supply and is housed in a small 8-pin mini-DIP and 8-pin SOIC. The part contains a 3.8 µs successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock and a high speed serial interface.Output data from the AD7895 is provided via a high speed, serial interface port. This two-wire serial interface has a serial clock input and a serial data output with the external serial clock accessing the serial data from the part.In addition to the traditional dc accuracy specifications such as linearity and full-scale and offset errors, the AD7895 is specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio.The part accepts an analog input range of ±10 V (AD7895-10), ±2.5 V (AD7895-3), 0 V to 2.5 V (AD7895-2) and operates from a single +5 V supply, consuming only 20 mW max.The AD7895 features a high sampling rate mode and, for low power applications, a proprietary automatic power-down mode where the part automatically goes into power down once conversion is complete and 'wakes up' before the next conversion cycle.The part is available in a small, 8-pin, 0.3' wide, plastic dual-in-line package (mini-DIP) and in an 8-pin, small outline IC (SOIC).PRODUCT HIGHLIGHTS Fast, 12-Bit ADC in 8-Pin Package The AD7895 contains a 3.8 µs ADC, a track/hold amplifier, control logic and a high speed serial interface, all in an 8-pin package. This offers considerable space saving over alternative solutions. Low Power, Single Supply Operation The AD7895 operates from a single +5 V supply and consumes only 20 mW. The automatic power-down mode, where the part goes into power-down once conversion is complete and “wakes up” before the next conversion cycle, makes the AD7895 ideal for battery-powered or portable applications. High Speed Serial Interface The part provides high speed serial data and serial clock lines allowing for an easy, two-wire serial interface arrangement.

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).
