LTC2640

Single 12-/10-/8-Bit SPI

V DACs with

OUT

10ppm/°C Reference

FEATURES

DESCRIPTION

Integrated Precision Reference

The LTC^®2640 is a family of 12-, 10-, and 8-bit voltage-

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

referenceinan8-leadTSOT-23package.Ithasarail-to-rail

output buffer that is guaranteed monotonic.

2.5V Full-Scale 10ppm/°C (LTC2640-L)

4.096V Full-Scale 10ppm/°C (LTC2640-H)

Maximum INL Error: 1LSB (LTC2640A-12)

Bidirectional Reference: Input or 10ppm/°C Output

TheLTC2640-Lhasafull-scaleoutputof2.5V,andoperates

from a single 2.7V to 5.5V supply. The LTC2640-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.

Low Noise (0.7mVpp, 0.1Hz to 200kHz)

Guaranteed Monotonic Over Temperature

2.7V to 5.5V Supply Range (LTC2640-L)

Low Power Operation: 180μA at 3V

Power Down to 1.8μA Maximum (C and I Grades)

Each DAC can also operate in External Reference mode,

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

scale output.

Asynchronous DAC Clear Pin (LTC2640-Z)

Power-On Reset to Zero or Mid-Scale options

Double-Buffered Data Latches

Guaranteed Operation from –40°C to 125°C (H-Grade)

8-Lead TSOT-23 (ThinSOT™) Package

The LTC2640 DACs use a SPI/MICROWIRE™ compatible

3-wire serial interface which operates at clock rates up

to 50MHz.

APPLICATIONS

The LTC2640 incorporates a power-on reset circuit. Op-

tions are available for Reset to Zero-Scale or Reset to

Mid-Scale after power-up.
