description

The LTC®2656 is an 8-channel 16-bit / 12-bit rail-to-rail DAC family with an accurate integration benchmark. These DACs feature built-in, high-performance, rail-to-rail output buffers and are guaranteed to be monotonous. The LTC2656-L has a 2.5V full-scale output with an integrated 10ppm/ºC reference and operates from a 2.7V to 5.5V operating supply. The LTC2656-H has a 4.096V full-scale output and integrated reference and is available from a single operating supply of 4.5V to 5.5V. 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.

These DACs communicate via an SPI / MICROWIRETM-compatible four-wire serial interface that operates at clock frequencies up to 50MHz. LTC2656 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
