description

LTC^®The 2654 is a family of 4-channel 16-bit/12-bit rail-to-rail DACs with an integrated 10 ppm/ºC maximum reference. These DACs have built-in high performance, rail-to-rail output buffers and are guaranteed monotonic. The LTC2654-L has a 2.5V full-scale output and integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2654-H has a 4.096V full-scale output and integrated reference and operates from a single 4.5V to 5.5V supply. Each DAC can also operate with an external reference that sets the DAC full-scale output to twice the external reference voltage.

THESE DCs go through an spi/microwire^TMCommunication is carried out by a compatible 4-wire serial interface that operates at clock frequencies up to 50MHz. The LTC2654 includes a power-on reset circuit controlled by the PORSEL pin. If the PORSEL pin is connected to GND, the DAC is reset to zero scale. If the PORSEL pin is connected to V_CC, the DAC will be reset to the intermediate scale.
