LTC1452/LTC1453

12-Bit Rail-to-Rail

Micropower DACs in SO-8

FEATURES

DESCRIPTIO

The LTC^®1451/LTC1452/LTC1453 are complete single

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

converters (DACs) in an SO-8 package. They include an

output buffer amplifier and an easy-to-use 3-wire

cascadable serial interface.

3V Operation (LTC1453), I_CC: 250µA Typ

5V Operation (LTC1451), I_CC: 400µA Typ

3V to 5V Operation (LTC1452), I_CC: 225µA Typ

Built-In Reference: 2.048V (LTC1451)

■

The LTC1451 has an onboard reference of 2.048V and a

full-scale output of 4.095V. It operates from a single 4.5V

to 5.5V supply.

1.220V (LTC1453)

■

Multiplying Version (LTC1452)

■

Power-On Reset

The LTC1452 is a multiplying DAC with a full-scale output

of twice the reference input voltage. It operates from a

single supply of 2.7V to 5.5V.

■

SO-8 Package

■

3-Wire Cascadable Serial Interface

■

Maximum DNL Error: 0.5LSB

■

Schmitt Trigger on Clock Input Allows Direct

The LTC1453 has an onboard 1.22V reference and a full-

scale output of 2.5V. It operates from a single supply of

2.7V to 5.5V.

Optocoupler Interface

APPLICATIO S

The low power supply current makes the LTC1451 family

ideal for battery-powered applications. The space saving

8-pin SO package and operation with no external compo-

nents provide the smallest 12-bit DAC system available.
