Product Details

describe:

The 20-bit DAC11001B is a high precision, low noise, voltage output, ADS7806PB single-channel digital-to-analog converter (DAC). The DAC11001B is monotonic by design and provides excellent linearity over all output ranges.

The unbuffered voltage output provides low noise performance (7 nV/√ Hz ) and 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 achieve clean waveform ramps with ultra-low total harmonic distortion (THD).

The DAC11001B device contains a power-on reset (POR) circuit so that the DAC starts up with a known value in the register. With an external reference, a DAC output range from V REFPF to V REFNF can be achieved, including asymmetric output ranges.

The DAC11001B uses a general-purpose 4-wire serial interface that operates at clock rates up to 50 MHz.
