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.
