TI Introduces Ultra-Low Glitch, 16-Bit DAC with Internal 2ppm/C Reference for Closed-Loop Control Applications
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
The DAC8560 is well-suited to work with TI’s MSP430 ultra-low-power microcontrollers, TMS320C2000™ 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.
