Detailed Description

LTC2655: Quad I2C 16-/12-Bit Rail-to-Rail DACs with 10ppm/C Max Reference.

The LTC2655 is a family of Quad I2C 16-/12-Bit Rail-to-Rail DACs with
integrated 10ppm/C max reference. The DACs have built-in high performance,
rail-to-rail, output buffers and are guaranteed monotonic. The LTC2655-L has a
full-scale output of 2.5V with the integrated reference and operates from a
single 2.7V to 5.5V supply. The LTC2655-H has a full-scale output of 4.096V with
the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can
also operate with an external reference, which sets the full-scale output to 2
times the external reference voltage.

The parts use the 2-wire I2C compatible serial interface. The LTC2655 operates
in both the standard mode (maximum clock rate of 100kHz) and the fast mode
(maximum clock rate of 400kHz). The LTC2655 incorporates a power-on reset
circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs
power-on reset to zero-scale. If PORSEL is tied to VCC, the DACs power-on reset
to mid-scale.
