DAC8560

SLAS464 – DECEMBER 2006

16-Bit, Ultra-Low Glitch, Voltage Output

DIGITAL-TO-ANALOG CONVERTER

with 2.5V, 2ppm/

°C Internal Reference

• Relative Accuracy: 4LSB

The DAC8560 is a low-power, voltage output, 16-bit

digital-to-analog converter (DAC). The DAC8560

• Glitch Energy: 0.15nV-s

includes a 2.5V, 2ppm/

°C internal reference (enabled

• MicroPower Operation: 510µA at 2.7V

by default), giving a full-scale output voltage range of

• Internal Reference:

2.5V. The internal reference has an initial accuracy

• 2.5V Reference Voltage (enabled by default)

• 0.02% Initial Accuracy

• Power Supply: +2.7V to +5.5V

processor (DSP) interfaces.

• 16-Bit Monotonic Over Temperature Range

The DAC8560 incorporates a power-on-reset circuit

• Settling Time: 10µs to ±0.003% FSR

that ensures the DAC output powers up at zero-scale

and remains there until a valid code is written to the

• Power-Down Capability

The low-power consumption, internal reference, and

battery-operated equipment. The power consumption

is 2.6mW at 5V, reducing to 6
