The LTM2894 is a complete galvanically-isolated USB 2.0 compatible ?Module? (micromodule) transceiver.The LTM2894 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device.The isolator ?Module technology uses coupled inductors to provide 7500VRMS of isolation and 17.4mm of creepage between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 50kV/?s.Enhanced ESD protection allows this part to withstand up to ?20kV (human body model) on the USB transceiver interface pins to local supplies and ?20kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition

The high speed SPI-compatible serial port supports 1.71V to 5.5V logic supplies. The LTM2895 is targeted at generic SPI and digital-to-analog converter applications.The isolation barrier tolerates large voltage ground variations between the logic interface and the isolated side of the LTM2895. Uninterrupted communication is maintained during voltage transients greater than 50kV/?s.Applications Remote Interface Control Industrial Process Control and Automation Test and Measurement Equipment Breaking Ground Loops

The ADuM3223/ADuM4223 are 4 A isolated, half-bridge gatedrivers that employ the Analog Devices, Inc., iCoupler? technology to provide independent and isolated high-side and low-sideoutputs. The ADuM3223 provides 3000 V rms isolation in thenarrow body, 16-lead SOIC package, and the ADuM4223 provides 5000 V rms isolation in the wide body, 16-lead SOIC package.Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers. The ADuM3223/ADuM4223 isolators each provide two independent isolated channels. They operate with an inputsupply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employinghigh voltage level translation methodologies, the ADuM3223/ADuM4223 offer the benefit of true, galvanic isolation between the input and each output. Each output may be continuously operated up to 537 V peak relative to the input, thereby supporting low-side switching to negative voltages. The differential voltagebetween the high-side and low-side may be as high as 800 V peak.As a result, the ADuM3223/ADuM4223 provide reliable controlover the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.Applications Switching power supplies Isolated IGBT/MOSFET gate drives Industrial inverters Automotive

An additionalfour inputs are available but are multiplexed with the four DACoutput pins. The four DAC outputs are available only on certainmodels (ADuC7020, ADuC7026, ADuC7028, and ADuC7029).However, in many cases where the DAC outputs are not present,these pins can still be used as additional ADC inputs, giving amaximum of 16 ADC input channels. The ADC can operate insingle-ended or differential input mode. The ADC input voltageis 0 V to VREF. A low drift band gap reference, temperature sensor,and voltage comparator complete the ADC peripheral set.Depending on the part model, up to four buffered voltageoutput DACs are available on-chip. The DAC output range isprogrammable to one of three voltage ranges.The devices operate from an on-chip oscillator and a PLLgenerating an internal high frequency clock of 41.78 MHz(UCLK). This clock is routed through a programmable clockdivider from which the MCU core clock operating frequencyis generated. The microcontroller core is an ARM7TDMI?,16-bit/32-bit RISC machine, which offers up to 41 MIPS peakperformance. Eight kilobytes of SRAM and 62 kilobytes ofnonvolatile Flash/EE memory are provided on-chip. TheARM7TDMI core views all memory and registers as a singlelinear array.On-chip factory firmware supports in-circuit serial downloadvia the UART or I2C serial interface port; nonintrusive emulationis also supported via the JTAG interface.
