ZHCSHR4F January 2009 – April 2018 DAC7568 , DAC8168 , DAC8568
PRODUCTION DATA.
Typical noise performance for the DAC7568, DAC8168, and DAC8568 with the internal reference enabled is shown in Figure 66 to Figure 67. Output noise spectral density at the VOUT pin versus frequency is depicted in Figure 66 for full-scale, midscale, and zero-scale input codes. The typical noise density for midscale code is 120nV/√Hz at 1kHz and 100nV/√Hz at 1MHz. High-frequency noise can be improved by filtering the reference noise. Integrated output noise between 0.1Hz and 10Hz is close to 6μVPP (midscale), as shown in Figure 67.
