Loop-Powered DAC Conserves Power.. 2 IF DAC Solution in Base Station Multioutput Low Jitter Clock Data Conversion Knowledge Resource .. 5 RF DACs Enable Bits-to-RF Mixed-Signal Front-End IC for Wireless Octal denseDAC® inWLCSP Package . .11 Versatile, Easy to Use, Precision New System Demonstration Platform Facilitates Quick Prototyping and data sheets, samples, THE ANALOG DEVICES SOLUTIONS BULLETIN DAC with Dynamic Power Control Optimizes Thermal Management in Multichannel Industrial Control Applications As the density of factory process control terminals increases, the system power dissipation reaches levels where thermal issues begin to undermine equipment performance, reliability, and safety. The AD5755 is a complete, multichannel control IC that incorporates on-chip dynamic power control with four precision 16-bit programmable voltage, or 4 mA to 20 mA current, output DACs. The dynamic power control works by continually sensing the load impedance and delivering the required power to the load while minimizing power loss in the rest of the system. This reduces self-heating and temperature elevation in dense, multichannel systems by 75% and lowers overall power consumption by 80% compared to other control technologies. The AD5755 offers fully specified performance with maximum total unadjusted error of 0.05% and a relative accuracy of ±0.006% max—meaning system calibration is no longer required. Supporting standard industrial voltage and current output ranges, the AD5755 can be used with standard HART protocol modems.

Loop-Powered DAC Conserves Power in Remote Industrial Applications Smart transmitters are powered from the 4 mA to 20 mA loop and, hence, operate within a limited power budget. As a result, the develop- ment of systems that accurately and efficiently monitor and transmit remote system measurements is an imposing challenge. To address this, system designers require a 4 mA to 20 mA loop-powered communication solution that is power efficient, highly accurate, and, ultimately, compact. The AD5421 has been specifically engineered to address this challenge by integrating on-board programmable power...

IF DAC Solutions in Base Station Transmit Architectures In W-CDMA, CDMA2000, TD-SCDMA, GSM, and WiMAX base station transmit applications, high performance DACs are commonly used to synthesize the l/Q intermediate frequency (IF) in the transmit signal chain architecture. As service providers are continually requiring more performance and functional integration delivered in a shrinking amount of space, it is incumbent upon system designers to choose optimal components for the task. Having a broad portfolio from which to choose the optimal component is mandatory. As the market leader in high speed...

New Direct Digital Synthesis (DDS) IC Delivers Power and Size Savings for Industrial and Communications Applications Large communication and instrumentation systems, such as wireless base stations and test and measurement equipment, have been taking advantage of fine frequency tuning, fast frequency hopping and settling times, and other performance benefits of DDS technol- ogy for over a decade. Now, designers of low power devices also seek to incorporate the benefits of DDS technology into their products without board space and power penalties. The AD9838 is a complete, low power, small package...

Data Conversion Knowledge Resource Designing analog and mixed-signal circuits is usually tougher than designing purely digital circuits, and high performance analog- to-digital or digital-to-analog conversion stages can be one of the toughest challenges of all. Data conversion involves many critical analog-oriented circuit considerations that directly impact the success of your design. To help with this challenge, Analog Devices has launched its new Data Conversion Knowledge Resource, which is an easy- to-navigate library of in-depth technical material focusing on all aspects of a conversion...
