The LTC®2636 is a family of octal 12-, 10-, and 8-bit
voltage-output DACs with an integrated, high-accuracy,
low-drift 10ppm/°C reference in 14-lead DFN and 16-lead
MSOP packages. It has a rail-to-rail output buffer and is
guaranteed monotonic. The LTC2636-L has a full-scale
output of 2.5V, and operates from a single 2.7V to 5.5V
supply. The LTC2636-H has a full-scale output of 4.096V,
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 the external reference voltage.
These DACs communicate via an SPI/MICROWIRE™-compatible
3-wire serial interface which operates at clock rates
up to 50MHz. Hardware clear (CLR) and asynchronous
DAC update (LDAC) pins are available in the MSOP package.
The LTC2636 incorporates a power-on reset circuit.
Options are available for reset to zero-scale or reset to
mid-scale in internal reference mode, or reset to mid-scale
in external reference mode after power-up.
