Adi Launches AdDSimI0pe Simulator for Mixed Signal Applications

Analog Devices, Inc. has launched ADIsimPE simulator for linear and mixed signal applications capable of virtual prototyping for customers with limited resources. The web-based ADIsimPower Design Center offers designers a complete, virtual evaluation ecosystem from customer requirements to solution based on a simple and quick 3-step design process aimed at reducing customer risk and dramatically improving time-to-market. The 3-step design process include: select the optimum solution based on efficiency, cost, area and component count; design and optimise using ADIsimPower downloadable tools; and simulate and verify using ADIsimPE. The ADIsimPE simulator includes a library of validated Analog Devices IC models and proven application schematics which can be edited to meet user requirements. For power management applications, system designers.

Analog Devices, Inc. Launches ADIsimPE Simulator for Mixed Signal Applications

Analog Devices, Inc. has launched ADIsimPE simulator for linear and mixed signal applications capable of virtual prototyping for customers with limited resources. ADIsimPE is powered by the SIMetrix/SIMPLIS simulator and utilizes SIMetrix SPICE for simulation of linear circuits, such as precision references, op amps and linear regulators, and SIMPLIS (SIMulation of Piecewise LInear Systems) for high speed analysis of non-linear circuits such as PLLs and switching power supplies - up to 50 times faster than the leading SPICE based simulators.

Analog Devices Introduces New Family of Digital Isolator Devices Optimized for SPI Communications Applications

Analog Devices, Inc. introduced a new family of digital isolator devices optimized for serial peripheral interface (SPI) communications systems. The ADuM315x SPIsolator(TM) digital isolator family is based on ADI's award-winning iCoupler(R) digital isolator technology, which has been shipped in volumes exceeding one billion channels. Supporting up to 40-MHz SPI clock speeds, the new digital isolators are over six times faster, over 80% smaller and cost as much as 85% less than competing optocoupler- or digital isolator-based solutions. Faster SPI clock speeds enable higher throughout in data acquisition systems, allowing for higher performance and more rapid system response times. A high level of functional integration provides system designers with a simple solution for isolating high-speed SPI signals along with commonly required low-speed status and control signals in a single package. The highly integrated ADuM315x SPI digital isolator family simplifies the design of a complete SPI digital isolation solution by using just three components, compared to the 18 to 32 components required by alternative digital isolator- or optocoupler-based solutions. The ADuM315x family features low propagation delay and jitter in the CLK, MO-SI, MI-SO and SS channels to support SPI clock rates of up to 40 MHz. The new digital isolators also support the maximum sample rate for select ADI 12-, 16- and 18-bit precision A/D converters. The family has a 3.75 kVrms isolation rating and will be followed later in 2014 by SPIsolator devices rated to 5 kVrms. The ADuM3150 supports a delayed clock output on the master side of the part that can be used with an additional general-purpose port on the master to support up to 40-MHz clock speeds. The ADuM3151, ADuM3152 and ADuM3153 provide four high-speed channels and three additional independent, low-data-rate channels in different configurations. The ADuM3154 digital isolator provides a slave-select multiplexing system that allows up to four slave devices to be serviced from one isolator.

Analog Devices, Inc. Introduces its Operational Amplifier ADA4870

Analog Devices, Inc. introduced the operational amplifier for driving heavy loads at high voltage and high output current, including piezoelectric transducers, PIN diodes, laser diodes, power FETs, coils and CCDs. The 40-V ADA4870 amplifier delivers over 1A of output current at more than twice the slew rate (2500 V/s) of competing high output-power amplifiers, enabling applications including higher accuracy, high-intensity focused ultrasound (HIFU) for medical equipment and higher efficiency envelope tracking solutions in small-cell base stations and military radios ADA4870 Improves System Performance and Cost. In HIFU equipment used for medical treatment and procedures, the ADA4870 provides wide bandwidth (52 MHz) and high slew rate to facilitate the high-voltage pulses necessary to drive the piezoelectric transducer, increasing accuracy and replacing large, costly discrete solutions. In small cell base stations and compact military radios, the ADA4870 improves power efficiency and extends battery life by assisting with the drive of the power amplifier's (PA) low impedance bias control to track the envelope of the RF signal, only using as much power for the PA as needed to pass the signal. In addition to HIFU and RF envelope tracking, the fast ADA4870 can be used to improve the driving of various high-capacitive and low-resistive loads including extending the bandwidth of high-voltage function generators and increasing automated test equipment drive capability and testing speeds, all while reducing solution size and cost. ADA4870 Key Features include: High output current drive: 1 A; Wide supply range: 10 V to 40 V; Wide output voltage swing: 37 V swing with 40 V supply; High slew rate: 2500 V/s; and Wide bandwidth: 52 MHz.
