Description
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 VREFPF to VREFNF can be achieved, including asymmetric output ranges.
The DACx1001 use a versatile 4–wire serial interface that operates at clock rates of up to 50 MHz. The DACx1001 is specified over the industrial temperature range of –40°C to +125°C.
