DESCRIPTION
Complete Single Supply
12-Bit Voltage Output
DAC in SO-8
The LTC1257 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 350A 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.
