The LTC1563-2/LTC1563-3 are a family of extremely easy-to-use, active RC lowpass filters with rail-to-rail inputs and outputs and low DC offset suitable for systems with a resolution of up to 16 bits. The LTC1563-2, with a single resistor value, gives a unity-gain Butterworth response. The LTC1563-3, with a single resistor value, gives a unity-gain Bessel response. The proprietary architecture of these parts allows for a simple resistor calculation:R = 10k (256kHz/fC); fC = Cutoff Frequencywhere fC is the desired cutoff frequency. For many applications,this formula is all that is needed to design a filter.By simply utilizing different valued resistors, gain andother responses are achieved.The LTC1563-X features a low power mode, for the lowerfrequency applications, where the supply current is reducedby an order of magnitude and a near zero powershutdown mode.The LTC1563-Xs are available in the narrow SSOP-16package (Same footprint as an SO-8 package).Applications Discrete RC Active Filters and Modules Antialiasing Filters Smoothing or Reconstruction Filters Linear Phase Filtering for Data Communication Phase Locked Loops

The ADE7978, the ADE7933/ADE7932, and ADE7923 form achipset dedicated to measuring 3-phase electrical energy usingshunts as current sensors.The ADE7933/ADE7932 are isolated, 3-channel sigma-deltaanalog-to-digital converters (?-? ADCs) for polyphase energymetering applications that use shunt current sensors.TheADE7923 is a nonisolated, 3-channel ?-? ADC for the neutral linethat uses a shunt current sensor. The ADE7932 features two ADCs,and the ADE7933 and ADE7923 feature three ADCs.One channel is dedicated to measuring the voltage across theshunt when a shunt is used for current sensing. This channelprovides a signal-to-noise ratio (SNR) of 67 dB over a 3.3 kHzsignal bandwidth. Up to two additional channels are dedicatedto measuring voltages, which are usually sensed using resistordividers.The unused voltage channels on the neutral ADE7923 can beused for auxiliary voltage measurements. These channels providean SNR of 75 dB over a 3.3 kHz signal bandwidth. One voltagechannel can be used to measure the temperature of the die viaan internal sensor.The ADE7933 and ADE7923 include three channels: onecurrent channel and two voltage channels. The ADE7932includes one current channel and one voltage channel, but isotherwise identical to the ADE7933.The ADE7933/ADE7932 include isoPower?, an integrated,isolated dc-to-dc converter. Based on the Analog Devices, Inc.,iCoupler? technology, the dc-to-dc converter provides theregulated power required by the first stage of the ADCs at a3.3 V input supply. The ADE7933/ADE7932 eliminate the needfor an external dc-to-dc isolation block. The iCoupler chip scaletransformer technology is used to isolate the logic signalsbetween the first and second stages of the ADC. The result is asmall form factor, total isolation solution. The ADE7923 is thenonisolated version of the ADE7933 that can be used forneutral current measurement when isolation from the neutralline is not required.The ADE7933/ADE7932 and ADE7923 contain a digital interfacethat is specially designed to interface with the ADE7978. Usingthis interface, the ADE7978 accesses the ADC outputs andconfiguration settings of the ADE7933/ADE7932 andADE7923.The ADE7933/ADE7932 are available in a 20-lead, Pb-free, widebodySOIC package with increased creepage. The ADE7923 isavailable in a similar 20-lead, Pb-free, wide-body SOIC packagewithout the increased creepage.The ADE7978 is a high accuracy, 3-phase electrical energymeasurement IC with serial interfaces and three flexible pulseoutputs. The ADE7978 can interface with up to four ADE7933/ADE7932 and ADE7923 devices. The ADE7978 incorporates allthe signal processing required to perform total (fundamental andharmonic) active, reactive, and apparent energy measurementand rms calculations, as well as fundamental-only active andreactive energy measurement and rms calculations. A fixedfunction digital signal processor (DSP) executes this signalprocessing.The ADE7978 measures the active, reactive, and apparent energyin various 3-phase configurations, such as wye or delta services,with both three and four wires. The ADE7978 provides systemcalibration features for each phase, gain calibration, and optionaloffset correction. Phase compensation is also available, but it isnot necessary because the currents are sensed using shunts. TheCF1, CF2, and CF3 logic outputs provide a wide selection ofpower information: total active, reactive, and apparent powers;the sum of the current rms values; and fundamental active andreactive powers. The ADE7978 incorporates power quality measurements, suchas short duration low or high voltage detection, short durationhigh current variations, line voltage period measurement, andangles between phase voltages and currents. Two serial interfaces,SPI and I2C, can be used to communicate with the ADE7978.A dedicated high speed interface?the high speed data capture(HSDC) port?can be used in conjunction with I2C to provideaccess to the ADC outputs and real-time power information.The ADE7978 also has two interrupt request pins, IRQ0 andIRQ1, to indicate that an enabled interrupt event has occurred.The ADE7978 is available in a 28-lead, Pb-free LFCSP package.Applications Shunt-based polyphase meters Power quality monitoring Solar inverters Process monitoring Protective devices Isolated sensor interfaces Industrial PLCs

The LTM2885 is a complete galvanically isolated full-duplex RS485/RS422 ?Module? (micromodule) transceiver. No external components are required. A single supply powers both sides of the interface through an integrated, isolated, low noise, efficient 5V output DC/DC converter.Coupled inductors and an isolation power transformer provide 6500VRMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients up to 50kV/?s.Maximum data rates are 20Mbps or 250kbps in slew limited mode. Transmit data, DI, and receive data, RO, are implemented with event driven low jitter processing. The receiver has a one-eighth unit load supporting up to 256 nodes per bus. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the transceiver interface pins to isolated supplies and ?25kV through the isolation barrier to logic supplies without latch-up or damage.APPLICATIONS Isolated RS485/RS422 Interface Industrial Networks Breaking RS485 Ground Loops Isolated PROFIBUS-DP Networks
