Product Details
The LTC2654 is a family of quad 16-/12-bit rail-to-rail DACs with integrated 10ppm/°C maximum reference . The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2654-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2654-H has a full-scale output of 4.096V with the integrated reference 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 2 times the external reference voltage.
These DACs communicate via a SPI/MICROWIRE™ compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2654 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale. If PORSEL is tied to VCC, the DACs reset to mid-scale.
