Embedded: Smallest, most flexible, multichannel D-A converters

All silicon in the AD57xx family from Analog Devices is housed in a 24-lead TSSOP, and sample units are now available. Integrated features may resolve difficult board design and layout challenges in factory process control and instrumentation systems.

Norwood, MAAnalog Devices Inc . (ADI) introduced what it reports to be the industry's smallest and most flexible, multichannel digital-to-analog converters (DACs). Said to be ideal for designers needing flexibility when specifying converters for high-voltage applications, such as factory process control, instrumentation, and dc setpoint-control applications, the offering includes 12 converters ranging from 12- to 16-bit dual and quad channel devices operating over a wide voltage range on either single or dual power supplies. Housed in small, pin-compatible, TSSOP (thin-shrink small-outline packages), the converters are more than 40% smaller than comparable devices. They integrate output amplifiers, references, and diagnostics. Eliminating discrete components, plus the small package size, translates into board space savings of as much as 70%, when compared to existing discrete offerings. That can resolve difficult board design and layout challenges in factory process control and instrumentation systems.

ADI, which says it's a global leader in high-performance semiconductors for signal-processing applications and the leading provider of data conversion technology, explains that the new highly configurable DACs feature software-programmable, unipolar and bipolar voltage output ranges that can be independently set per channel. This gives designers the option to eliminate a number of discrete components, such as precision resistors, switches, and external amplifiers.

By taking advantage of the AD5754R 's 16-bit performance and excellent TUE (total unadjusted error), designers can reduce cost by eliminating time-consuming factory calibration sequences, the company says. When designed into PLC (programmable logic controller) analog output modules or data-acquisition cards, the flexibility of the output range, operation with multiple supplies, and specified TUE combine to eliminate mechanical jumpers and factory calibration sequences. Results are faster design cycles, accelerated time-to-market, and reduced costs. The flagship component in the AD57xx DAC family (the 16-bit monotonic AD5754R) achieves an accuracy level of 0.1% (max) TUE, and includes a precision 5-ppm/deg C internal reference.

The AD572x, AD573x, and AD575x families are offered in dual and quad configurations in resolutions of 12, 14 and 16 bits and operate from single supply voltages of 4.5 V to 16.5 V, or dual supply voltages of
