DS3911T+

The DS3911T+ is a temperature-controlled, non-volatile (NV), I2C quad digital to analogue converter (DAC)in 14 pin TDFN package. The quad, 10bit delta-sigma output, NV controller features an on-chip temperature sensor and associated 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 analogue 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. It is typically used at active optical cables, optical transceivers, linear and nonlinear compensation, instrumentation and industrial controls.

• Supply voltage range from 2.8V to 5.5V
• Operating temperature range from -40°C to 100°C
• Four 10bit delta sigma outputs
• On-chip temperature sensor and ADC
• I2C compatible serial interface
• Address pins allow up to four DS3911s to share the same I2C bus
