The LTC2632 is a family of dual 12-, 10-, and 8-bit voltage-output DACs with an integrated, high-accuracy, low-drift reference in an 8-lead TSOT-23 package. It has rail-to-rail output buffers and is guaranteed monotonic.
The LTC2632-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2632-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 a simple SPI/MICROWIRE compatible 3-wire serial interface which operates at clock rates up to 50MHz. The LTC2632 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.
