Description
The LTC®2640 is a family of 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 a rail-to-rail output buffer that is guaranteed monotonic.The LTC2640-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2640-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. A 10 ppm/°C reference output is available at the REF pin.
Each DAC can also operate in External Reference mode, in which a voltage supplied to the REF pin sets the full- scale output.
The LTC2640 DACs use a SPI/MICROWIRE™ compatible 3-wire serial interface which operates at clock rates up to 50 MHz.
The LTC2640 incorporates a power-on reset circuit. Options are available for Reset to Zero Scale or Reset to Midscale after power-up.
