Description
General part information
DAC11001A Series
The 20-bit DAC11001A, 18-bit DAC91001, and 16-bit DAC81001 (DACx1001) are highly accurate, low-noise, voltage-output, single-channel, digital-to-analog converters (DACs). The DACx1001 are specified monotonic by design, and offer excellent linearity of less than 4 LSB (max) across all ranges.
The unbuffered voltage output offers low noise performance (7 nV/√Hz) in combination with a fast settling time (1µs), making this device an excellent choice for low-noise, fast control-loop, and waveform generation applications. The DACx1001 integrates an enhanced deglitch circuit with code-independent ultra-low glitch (1 nV-s) to enable clean waveform ramps with ultra-low total harmonic distortion (THD).
The DACx1001 devices incorporate a power-on-reset circuit so that the DAC powers with known values in the registers. With external references, DAC output ranges from VREFPFto VREFNFcan be achieved, including asymmetric output ranges.
