LTC263x Video Product Brief

Sep 18 2017

The LTC263x is a family of single/dual/quad/octal 12-, 10-, and 8-bit voltage-output DACs with an integrated, high-accuracy, low-drift 10ppm/°C reference in small packages. They have a rail-to-rail output buffer and are guaranteed monotonic. The LTC263x-L versions have a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC263x-H have 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, depending on the product selected communicate via an SPI/MICROWIRE-compatible 3-wire serial interface which operates at clock rates up to 50MHz or a 400kHz I2C interface. Hardware clear (CLR) and asynchronous DAC update (LDAC) pins are available in the some versions. The LTC263x incorporate 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. Reset to high-Z is also available for the LTC2633 and LTC2635.
