Product Details

The DS3911 is a quad, 10-bit delta-sigma output, nonvolatile (NV) controller that features an on-chip temperature sensor and associated analog-to-digital converter (ADC). The integrated temperature sensor indexes the up to 2°C resolution NV lookup tables (LUTs), encompassing a -40°C to +100°C 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 output with arbitrary slope. Programming is accomplished by an I²C-compatible interface that operates at speeds of up to 400kHz.
