LT LTC2634IMSE-LZ8#PBF

Voltage - BufferedSPI2.7V ~ 5.5V-40°C ~ 85°C

Overview

The LTC2634 is a family of quad 12-, 10- and 8-bit voltage output DACs with an integrated, high accuracy, low drift 10ppm/°C reference in 16-lead QFN and 10-lead MSOP packages. 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. The LTC2634-H has a full-scale output of 4.096V, 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 the external reference voltage.

These DACs communicate 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. The LTC2634 incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale in internal reference mode, or reset to mid-scale in external reference mode after power-up.
