LTC1257

Complete Single Supply

12-Bit Voltage Output

DAC in SO-8

FEATURES

DESCRIPTION

The LTC^®1257 is a complete single supply, 12-bit voltage

output D/A converter (DAC) in an SO-8 package. The

LTC1257 includes an output buffer amplifier, 2.048V volt-

age reference and an easy to use 3-wire cascadable serial

interface. An external reference can be used to override

the internal reference and extend the output voltage range

to 12V. The power supply current is a low 350µA when

operating from a 5V supply, making the LTC1257 ideal

for battery-powered applications. The space-saving 8-pin

SO package and operation with no external components

provide the smallest 12-bit D/A system available.

8-Pin SO Package

Buffered Voltage Output
