I C Quad DAC  
General Description  
Features  
The DS3911 is a quad, 10-bit delta-sigma output, nonvol-  
atile (NV) controller that features an on-chip temperature  
sensor and associated analog-to-digital converter (ADC).  
The integrated temperature sensor indexes the up to  
2NC resolution NV lookup tables (LUTs), encompassing  
a -40NC to +100NC temperature range. The LUT directly  
drives the delta-sigma digital-to-analog converter (DAC)  
outputs. This flexible LUT-based architecture allows the  
device to provide a temperature-compensated DAC out-  
put with arbitrary slope. Programming is accomplished
