ANALOG OUTPUTS The output amplifier can swing to within 1.4V of the supply rails, specified over the – +85 C temperature range. This allows for a 10V DAC voltage output operation from 12V supplies with a typical 5% ...

DAC RESET The RST and RSTSEL inputs control the reset of the analog output. The reset command is level triggered by a low signal on RST. Once RST is LOW, the DAC output will begin settling to the mid-scale or ...

OFFSET ADJUSTMENT Offset adjustment is accomplished by introducing a small current into the summing junction (SJ) of the DAC7741. The voltage at SJ dependent on the output configura- SJ tion of the DAC7741. See Table IV ...

NOISE PERFORMANCE Increased noise performance of the DAC output can be achieved by filtering the voltage reference input to the DAC7741. Figure 10 shows a typical internal reference filter schematic. A low-pass filter applied between the REF REF pins can ...
