LTC2656BCUFD-H16#PBF

LTC2656BCUFD-H16#PBF is an octal, 16bit, rail-to-rail DAC with a precision integrated reference. LTC2656-H has built-in high-performance, rail-to-rail, output buffers and a guaranteed monotonic. The LTC2656-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. These DACs also operate with an external reference, which sets the DAC full-scale output to two 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 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.
