The ADE7880 is high accuracy, 3-phase electrical energy measurement IC with serial interfaces and three flexible pulse outputs. The ADE7880 device incorporates second-order sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), a digital integrator, reference circuitry, and all of the signal processing required to perform the total (fundamental and harmonic) active, and apparent energy measurements, rms calculations, as well as fundamental-only active and reactive energy measurements. In addition, the ADE7880 computes the rms of harmonics on the phase and neutral currents and on the phase voltages, together with the active, reactive, and apparent power, and the power factor and harmonic distortion on each harmonic for all phases. Total harmonic distortion plus noise (THD + N) is computed for all currents and voltages. A fixed function digital signal processor (DSP) executes this signal processing. The DSP program is stored in the internal ROM memory.The ADE7880 is suitable for measuring active, reactive, and apparent energy in various 3-phase configurations, such as wye or delta services with both three and four wires. The ADE7880 provides system calibration features for each phase, that is, rms offset correction, phase calibration, and gain calibration. The CF1, CF2, and CF3 logic outputs provide a wide choice of power information: total active powers, apparent powers, or the sum of the current rms values, and fundamental active and reactive powers.The ADE7880 contains waveform sample registers that allow access to all ADC outputs. The devices also incorporate power quality measurements, such as short duration low or high voltage detections, short duration high current variations, line voltage period measurement, and angles between phase voltages and currents. Two serial interfaces, SPI and I2C, can be used to communicate with the ADE7880. A dedicated high speed interface, the high speed data capture (HSDC) port, can be used in conjunction with I2C to provide access to the ADC outputs and real-time power information. The ADE7880 also has two interrupt request pins, IRQ0 and IRQ1, to indicate that an enabled interrupt event has occurred. Three specially designed low power modes ensure the continuity of energy accumulation when the ADE7880 is in a tampering situation. The ADE7880 is available in the 40-lead LFCSP, Pb-free package, pin-for-pin compatible with ADE7854, ADE7858, ADE7868, and ADE7878 devices.APPLICATIONS Energy metering systems Power quality monitoring Solar inverters Process monitoring Protective devices

The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 1 mg/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 μg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 μg/√Hz typical) can be selected at minimal increase in supply current.In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm × 3.25 mm × 1.06 mm package.APPLICATIONS Hearing aids Home healthcare devices Motion enabled power save switches Wireless sensors Motion enabled metering devices

The device is capable of delivering 2 × 10 W of continuous output power into a 4 Ω load (or 2 × 8 W into 8 Ω) with 98 dB. Spread spectrum pulse density modulation (PDM) is used toprovide lower EMI radiated emissions compared with other Class-D architectures. The SSM3302 includes an optional modulation select pin (ultralow EMI emission mode) that significantly reduces the radiated emissions at the Class-D outputs, particularly above 100 MHz. The SSM3302 can pass FCC Class-B emissions testing with an unshielded 20 inch cable using common-mode choke-based filtering.The fully differential input of the SSM3302 provides excellent rejection of common-mode noise on the input. The device also includes a highly flexible gain select pin that only requires one series resistor to choose a gain between 9 dB and 24 dB, with no change to the input impedance. The benefit of this is to improve gain matching between multiple SSM3302 devices within a single application compared with using external resistors to set gain.The SSM3302 includes an integrated voltage regulator thatgenerates a 5 V rail.The SSM3302 has a micropower shutdown mode with a typical shutdown current of 10 μA. Shutdown is enabled by applying a logic low to the SD pin. The device also includes pop-and-click suppression circuitry that minimizes voltage glitches at the output during turn on and turn off, reducing audible noise during activation and deactivation.Other included features to simplify system level integration of the SSM3302 are input low-pass filtering to suppress out-ofband DAC noise interference to the pulse density modulator, fixed input impedance to simplify component selection across multiple platform production builds, and a thermal warning indicator pin.The SSM3302 is specified over the commercial temperaturerange (−40°C to +85°C).

The LTC3604 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying up to 2.5A of output current. The operating supply voltage range is from 3.6V to 15V, making it suitable for a wide range of power supply applications. The operating frequency is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors. For switching noise sensitive applications, the LTC3604 can be externally synchronized over the same frequency range. An internal phase-locked loop aligns the on-time of the top power MOSFET to the internal or external clock. This unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response. The LTC3604 offers two operational modes: Burst Mode operation and forced continuous mode to allow the user to optimize output voltage ripple, noise, and light load efficiency for a given application. Maximum light load efficiency is achieved with the selection of Burst Mode operation while forced continuous mode provides minimum output ripple and constant frequency operation.Applications Distributed Power Systems Lithium-Ion Battery-Powered Instruments Point-of-Load Power Supplies
