DESCRIPTION

The

LTC

2637

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 LTC2637-L has a full-scale

output of 2.5V, and operates from a single 2.7V to 5.5V

supply. The LTC2637-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 a 2-wire I

C-compatible

serial interface. The LTC2637 operates in both the stan-

dard mode (clock rate of 100kHz) and the fast mode (clock

rate of 400kHz). The LTC2637 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.
