The LTC
1450/LTC1450L are complete single supply, rail-
to-rail voltage output, 12-bit digital-to-analog converters
(DACs) in a 24-pin SSOP or PDIP package. They include an
output buffer amplifier, reference and a double buffered
parallel digital interface.
The LTC1450 operates from a 4.5V to 5.5V supply. The
output can be pin strapped for 4.095V or 2.048V full-scale.
It has a 2.048V internal reference.
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.
