LTC2634CMSE-LZ12#PBF

LTC2634CMSE-LZ12#PBF is a quad 12bit voltage output DAC. It has rail-to-rail output buffers and is guaranteed monotonic. The LTC2634-L has a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. This DAC can also operate with an external reference, which sets the full-scale output to the external reference voltage. This DAC communicates via an SPI/MICROWIRE compatible 3-wire serial interface which operates at clock rates up to 50MHz. Serial data output (SDO), a hardware clear (CLR), and an asynchronous DAC update (LDAC) capability are available in the QFN package. Applications include mobile communications, process control and industrial automation, automatic test equipment, portable equipment, automotive.
