LTC2656BCFE-L16#PBF

LTC2656BCFE-L16#PBF is an octal 16bit rail-to-rail DAC. The DACs have built-in high-performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2656-L has a full-scale output of 2.5V with the integrated 10ppm/°C reference and operates from a single 2.7V to 5.5V supply. These DACs communicate via a SPI/MICROWIRE™ compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2656 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. Applications include mobile communications, process control and industrial automation, instrumentation, automatic test equipment, and automotive.
