Description for the DAC91001

The 20-bit DAC11001A, 18-bit DAC91001, and 16-bit DAC81001 (DACx1001) are highlyaccurate, low-noise, voltage-output, single-channel, digital-to-analog converters (DACs). TheDACx1001 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 (7nV/√Hz) in combination with a fast settling time (1µs), making this devicean excellent choice for low-noise, fast control-loop, and waveform generation applications. TheDACx1001 integrates an enhanced deglitch circuit with code-independent ultra-low glitch (1 nV-s) toenable clean waveform ramps with ultra-low total harmonic distortion (THD).

The DACx1001 devices incorporate a power-on-reset circuit so that the DAC powers withknown values in the registers. With external references, DAC output ranges fromVREFPF to VREFNF can be achieved, includingasymmetric output ranges.

The DACx1001 use a versatile 4–wire serial interface that operates at clock rates of upto 50 MHz. The DACx1001 is specified over the industrial temperature range of –40°C to+125°C.
