FEATURES

LTC2636

Octal 12-/10-/8-Bit SPI V

OUT

DACs with10ppm/°C Reference

DESCRIPTION

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-com-

patible 3-wire serial interface which operates at clock

rates up to 50MHz. Hardware clear (CLR) and asynchro-

nous 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.
