description

The LTC®2654 is a 4-channel 16-bit/12-bit rail-to-rail DAC family with an integrated 10 ppm/ºC maximum reference. These DACs have built-in high-performance, rail-to-rail output buffers and are guaranteed to be monotonous. The LTC2654-L has a 2.5V full-scale output and integrated reference and is available from a 2.7V to 5.5V single-operation supply. The LTC2654-H has a 4.096V full-scale output and integrated reference and is available from a single-operating 4.5V to 5.5V supply. Each DAC can also operate with an external reference that is responsible for setting the DAC's full-scale output to twice the external reference voltage. The DACs communicate via an SPI/MICROWIRETM-compatible four-wire serial interface that operates at clock frequencies up to 50MHz. 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 the VCC, the DAC will be reset to the intermediate scale.
