GENERAL DESCRIPTION

The AS5181 is a 10-bit, current-output digital-to-analog

converter (DAC) designed for superior performance in signal

reconstruction or arbitrary waveform generation applications

requiring analog signal reconstruction with low distortion

and low-power operation. The AS5181 are designed for a

10pVs glitch operation to minimize unwanted spurious signal

components at the output. An on-board 1.2V bandgap circuit

provides a well-regulated, low-noise reference that can be

disabled for external reference operation.

The devices are designed to provide a high level of sig-

nal integrity for the least amount of power dissipation. They

operate from a single 2.7V to 3.3V supply. Additionally,

these DACs have three modes of operation: normal, low-

power standby, and full shutdown, which provides the lowest

possible power dissipation with a 1μA (max) shutdown current.

A fast wake-up time (0.5μs) from standby mode to full DAC

operation facilitates power conservation by activating the DAC

only when required.
