TI Introduces Ultra-Low Glitch, 16-Bit DAC with Internal 2ppm/C Reference for Closed-Loop Control Applications

TI Introduces Ultra-Low Glitch, 16-Bit DAC with Internal 2ppm/C Reference for Closed-Loop Control Applications

DALLAS, March 30 /PRNewswire/ -- Texas Instruments Incorporated (TI) today introduced the first product in a new series of precision digital-to-analog converters (DACs) with an integrated precision reference. The DAC8560 is a 16-bit, single-channel DAC featuring ultra-low glitch (0.15nV-s), ultra-low-power (1.5mW at 2.7V) and an internal reference with 2ppm/C temperature drift and +/-0.004 percent initial accuracy. The combination of a precision DAC and outstanding reference performance makes the DAC8560 a flexible, easy-to-use solution for closed-loop control applications found in portable instrumentation, optical networking, industrial process control, machine and motion control, and data acquisition systems. (See http://www.ti.com/sc07067.)

The DAC8560 builds upon TI's recently released DAC855x series offering breakthrough performance while minimizing code-to-code output transient voltages (glitch). The low-glitch performance solves the common DAC problem of unwanted transient voltages which cause ringing in closed-loop systems and create harmonic distortion during waveform generation.

The device also incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device. A power-down feature, accessed over the serial interface, reduces the current consumption to 1.2uA at 5V.

Other features include 4LSB typical integral nonlinearity (INL), 0.5LSB typical differential nonlinearity (DNL), 8us typical settling time to +/-0.003 percent full-scale range and 16-bit monotonicity over temperature range.

The DAC8560 is well-suited to work with TI's MSP430 ultra-low-power microcontrollers, TMS320C2000(TM) digital signal controllers and high-performance analog portfolio to provide a complete system solution.

Availability and Packaging

The DAC8560 is available now in an MSOP-8 package from TI and its authorized distributors. Pricing starts at $3.50 in 1,000-piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available. The new 16-bit value performance offering also includes the DAC8550, DAC8551, DAC8552, DAC8554 and DAC8555 products.

TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.

Digital Transformation is much more than a buzzword. The radical shift to digital mechanisms for almost every process is evident across all industries and verticals. This is often especially true in financial services, where the legacy environment is many times unable to keep up with the rapidly shifting demands of the consumer. The constant pressure to provide complete, omnichannel delivery of customer-facing solutions to meet both regulatory and customer demands is putting enormous pressure on...
IoT is rapidly becoming mainstream as more and more investments are made into the platforms and technology. As this movement continues to expand and gain momentum it creates a massive wall of noise that can be difficult to sift through. Unfortunately, this inevitably makes IoT less approachable for people to get started with and can hamper efforts to integrate this key technology into your own portfolio. There are so many connected products already in place today with many hundreds more on the h...
The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addr...
