The 20-bit DAC11001B is a highly accurate, low-noise, voltage-output, single-channel, digital-to-analog converter (DAC). The DAC11001B is specified monotonic by design, and offers excellent linearity across all output ranges.

The unbuffered voltage output offers low noise performance (7 nV/√Hz) in combination with a fast settling time (1 µs), making this device an excellent choice for low-noise, fast control-loop, and waveform-generation applications. The DAC11001B 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 DAC11001B device incorporates a power-on-reset (POR) circuit so that the DAC powers on with known values in the registers. With external references, DAC output ranges from VREFPF to VREFNF can be achieved, including asymmetric output ranges.

The DAC11001B uses a versatile 4–wire serial interface that operates at clock rates of up to 50 MHz.
