Detailed Description

LTC2656: Octal SPI 16-/12-Bit Rail-to-Rail DACs with 10ppm/C Max Reference.

The LTC2656 is a family of octal 16-/12-bit rail-to-rail DACs with a precision
integrated reference. The DACs have built-in high performance, rail-to-rail,
output buffers and are guaranteed monotonic. The LTC2656-L has a full-scale
output of 2.5V with the integrated 10ppm/C reference and operates from a single
2.7V to 5.5V supply. The LTC2656-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 DAC full-scale output to two
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 LTC2656 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.
