LTC1450/LTC1450L

Parallel Input, 12-Bit

Rail-to-Rail Micropower

DACs in SSOP

FEATURES

DESCRIPTION

TheLTC^®1450/LTC1450Larecompletesinglesupply,rail-

to-rail voltage output, 12-bit digital-to-analog converters

(DACs)ina24-pinSSOPorPDIPpackage.Theyincludean

output buffer amplifier, reference and a double buffered

parallel digital interface.

■

12-Bit Resolution

■

3V Operation (LTC1450L) I_CC: 250µA Typ

■

5V Operation (LTC1450) I_CC: 400µA Typ

■

Parallel 12-Bit or 8 + 4-Bit Double Buffered

The LTC1450 operates from a 4.5V to 5.5V supply. The

outputcanbepinstrappedfor4.095Vor2.048Vfull-scale.

It has a 2.048V internal reference.

Digital Input

■

Internal Reference

■

Output Buffer Configurable to Gain of 1 or 2

Configurable as a Multiplying DAC

Internal Power-On Reset

■

The LTC1450L operates from a 2.7V to 5.5V supply. The

output can be pin strapped for 2.5V or 1.22V full-scale. It

has a 1.22V internal reference.

■

The LTC1450/LTC1450L offer true stand-alone perfor-

mance. In addition, the reference output, high and low

reference inputs and gain setting resistor are brought to

pins for maximum flexibility.

APPLICATIONS

■

Digital Calibration

Industrial Process Control

Automatic Test Equipment

Arbitrary Function Generators

Battery-Powered Data Conversion Products

Feedback Control Loops and Gain Control
