LTC2655BIUF-L16#PBF

LTC2655BIUF-L16#PBF is a quad I²C 16bit rail-to-rail DAC 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 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. Applications include mobile communications, process control and industrial automation, instrumentation, automatic test equipment, and automotive.
