DS3911
Temperature-Controlled, Nonvolatile,
I2C Quad DAC
General Description
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
by an I2C-compatible interface that operates at speeds
of up to 400kHz.
