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 DACx10...
