TI introduces industry’s first4-20mA DAC with integrated buck/boost converter.

Jump to the comments

Texas Instruments (TI) (NASDAQ:TXN) today introduceda digital-to-analog converter (DAC) that combines industry-leading precision performance with simpler power-supply design. The16-bitDAC8775operates from a single, wide12- to 36-V power rail, leveraging an integrated buck/boost converter to generate all of the required internal power suppliesto save designers time, cost and significant board space.

The four-channel DAC8775 addresses the trend in factory automation and process control equipment toward input/output (I/O) modulesthat must squeeze more channels intoa smaller space. Engineers designing these systems facethe challenge of managing power dissipation in a small form factor.By combining a 4-20mA current and voltage driverwith a precision reference and a buck/boost converter, the DAC8775 enablesa total system footprint that is up to 25 percent smaller than the nearest competing device. Expanding TI’s versatile portfolio of precision data converters, this highly integratedDAC can deliver smaller and more efficient designs with advanced diagnostic capabilities.

Key features and benefits of the DAC8775 data converter

·         More reliable system design: The DAC8775’s on-chip diagnostic features include smart alarms that monitor open load, short circuit, over-temperature, cyclic redundancy check (CRC), watchdog timerand compliance voltage. Designers canchoose preset actionsthat help detect faults early to facilitatereliable system operation.

·         Efficiency with fast response times: The device has an innovative auto-learn featurethatcalculates the load impedance on the 4-20mA loop and clamps the power supply. This enables faster settling time, balancing efficiency with quicker system response.

  • HighDC performance:A total unadjusted error of 0.1 percent full-scale range(FSR) over an extended industrial temperature range of -40°C to 125°C enables designers to rate their output modules for higher temperature ranges.The DAC8775’s high DC performancereducesthe need for system calibration, saving manufacturing costs compared to a discrete solution.
  • Thermally optimized design: The DAC8775 dynamically adjusts the generated supply based on the current load on the 4-20mA loop. This creates an efficient system with well-controlled thermal performance, allowing more channels in a smaller space.

valwriting prices

I have never visited energetica site but I was searching about DAC with buck/boost converter then directed here by google. I have been waiting for prices to decrease so I can purchase its service in an affordable range.
