FEATURES n n n n n n n n n n n LTC2636 Octal 12-/10-/8-Bit SPI VOUT DACs with10ppm/°C Reference DESCRIPTION The LTC®2636 is a family of octal 12-, 10-, and 8-bit voltage-output DACs with an integrated, high-accuracy, low-drift 10ppm/°C reference in 14-lead DFN and 16-lead MSOP packages. It has a rail-to-rail output buffer and is guaranteed monotonic. The LTC2636-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2636-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 DAC 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. Hardware clear (CLR) and asynchronous DAC update (LDAC) pins are available in the MSOP package. The LTC2636 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.
