Low glitch, 16-bit DAC dissipates 1.5 mW at 2.7 V

Dallas, Texas — Texas Instruments introduced a series of digital-to-analog converters (DACs) with an integrated precision reference. The DAC8560 is a 16-bit, single-channel DAC featuring low glitch (0.15 nV-s), low-power (1.5 mW at 2.7 V), an internal reference with 2 ppm/°C temperature drift and ±0.004 percent initial accuracy. The DAC is suitable for closed-loop control applications including portable instrumentation, optical networking, industrial process control, machine and motion control, and data acquisition systems. The DAC8560 builds upon TI's DAC855x series, which minimizes 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 1.2 µA at 5 V. Other features include 4 LSB typical integral nonlinearity (INL), 0.5 LSB typical differential nonlinearity (DNL) and 16-bit monotonicity over temperature range.
