LTC2654BCUF-H16#PBF

LTC®2654 is a family of quad 16bit rail-to-rail DAC with integrated 10ppm/°C maximum reference. The DAC have built-in high performance, rail-to-rail, output buffer and is guaranteed monotonic. The LTC2654-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. This DAC communicates via a SPI/MICROWIRE compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2654 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale. If PORSEL is tied to VCC, the DACs reset to mid-scale. Typical applications include mobile communications, process control and industrial automation, instrumentation, automatic test equipment, and automotive.
