DESCRIPTION
The LTC®2655 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 refer ence 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.
