Precision Digital To Analog Converter - DAC8560 - Texas Instruments

Texas Instruments introduced the DAC8560, new family of precision digital-to-analog converters (DACs) with internal 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 DAC8560 precision digital-to-analog converter is suitable for closed-loop control applications found in portable instrumentation, industrial process control, optical networking, data acquisition and robotic.

The DAC8560 precision digital-to-analog converter, offers minimal code-to-code output transient voltages. 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 precision digital-to-analog converter 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 precision digital-to-analog converter 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.
