DS3911 Temperature-Controlled, Nonvolatile, 2 I C Quad DAC General Description Features The DS3911 is a quad, 10-bit delta-sigma output, nonvol- S Four 10-Bit Delta-Sigma Outputs atile (NV) controller that features an on-chip temperature S On-Chip Temperature Sensor and ADC sensor and associated analog-to-digital converter (ADC). S Four Temperature-Indexed LUTs, Up to 2NC The integrated temperature sensor indexes the up to Resolution 2NC resolution NV lookup tables (LUTs), encompassing 2 a -40NC to +100NC temperature range. The LUT directly S I C-Compatible Serial Interface drives the delta-sigma digital-to-analog converter (DAC) S Address Pins Allow Up to Four DS3911s to Share outputs. This flexible LUT-based architecture allows the 2 the Same I C Bus device to provide a temperature-compensated DAC out- S 2.8V to 5.5V Digital Supply put with arbitrary slope. Programming is accomplished 2 S -40NC to +100NC Operating Temperature Range by an I C-compatible interface that operates at speeds of up to 400kHz.
