LTC2634

Quad 12-/10-/8-Bit

Rail-to-Rail DACs with

10ppm/°C Reference

Features

Description

The LTC

2634 is a family of quad 12-, 10- and 8-bit volt-

age output DACs with an integrated, high accuracy, low

drift 10ppm/°C reference in 16-lead QFN and 10-lead

MSOP packages. It has rail-to-rail output buffers and is

guaranteed monotonic. The LTC2634-L has a full-scale

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

supply. The LTC2634-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

full-scale output to the external reference voltage.

These DACs communicate via an SPI/MICROWIRE compat-

ible 3-wire serial interface which operates at clock rates

up to 50MHz. Serial data output (SDO), a hardware clear

(CLR), and an asynchronous DAC update (LDAC) capability

are available in the QFN package. The LTC2634 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.
