Product Details
The LTC2630 is a family of 12-, 10-, and 8-bit voltage output DACs with an integrated, high-accuracy, low-drift reference in a 6-lead SC70 package. It has a rail-to-rail output buffer and is guaranteed monotonic.
The LTC2630-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2630-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. Each DAC can also operate in supply as reference mode, which sets the full-scale output to the supply voltage.
The parts use a simple SPI/MICROWIRE™ compatible 3-wire serial interface which operates at clock rates up to 50MHz.
The LTC2630 incorporates a power-on reset circuit. Options are available for reset to zero or reset to midscale after power-up.
