FEATURES

LTC2631

Single 12-/10-/8-Bit I

OUT

DACs with

10ppm/°C Reference

DESCRIPTION

The LTC

2631 is a family of 12-, 10-, and 8-bit voltage-

output DACs with an integrated, high accuracy, low-drift

reference in an 8-lead TSOT-23 package. It has a rail-to-rail

output buffer that is guaranteed monotonic.

The LTC2631-L has a full-scale output of 2.5V, and oper-

ates from a single 2.7V to 5.5V supply. The LTC2631-H

has a full-scale output of 4.096V, and operates from a 4.5V

to 5.5V supply. A 10ppm/°C reference output is available

at the REF pin.

Each DAC can also operate in External Reference mode,

in which a voltage supplied to the REF pin sets the full-

scale output.

The LTC2631 DACs use a 2-wire, I

C-compatible serial

interface. The LTC2631 operates in both the standard

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

rate of 400kHz).

The LTC2631 incorporates a power-on reset circuit. Op-

tions are available for reset to zero-scale or reset to mid-

scale after power-up.
