Product Overview

The LTC2657CUFD-L12#PBF is an octal I²C 12-Bit rail-to-rail Digital-to-analog Converter (DAC) with integrated 10ppm/°C maximum reference. The DAC has built-in high performance, rail-to-rail, outputs buffers and is guaranteed monotonic. The LTC2657-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7 to 5.5V supply. The DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage. The part uses a 2-wire I²C compatible serial interface. The LTC2657 operates in both the standard mode and the fast mode. The LTC2657 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DAC reset to zero-scale at power-up. If PORSEL is tied to VCC, the DAC reset to mid-scale at power-up.
  • Selectable internal or external reference
  • Integrated reference buffers
  • Ultralow crosstalk
  • Power-on-reset to zero-scale/mid-scale
