The LTC
1659 is a single supply, rail-to-rail voltage out-
put, 12-bit digital-to-analog converter (DAC) in an MSOP
package. It includes a rail-to-rail output buffer amplifier
and an easy-to-use 3-wire cascadable serial interface.
The LTC1659 output swings from 0V to REF. The REF input
can be tied to V
CC
which can range from 2.7V to 5.5V. This
allows a rail-to-rail output swing from 0V to V
CC
. The
LTC1659 draws only 250
μ
A from a 5V supply.
Its guaranteed
±
0.5LSB maximum DNL makes the LTC1659
excel in calibration, control and trim/adjust applications.
The low power supply current and the small MSOP pack-
age make the LTC1659 ideal for battery-powered applica-
tions.
