DESCRIPTION
12-Bit Rail-to-Rail
Micropower DAC in
MSOP Package
The LTC
®
1659 is a single supply, rail-to-rail voltage output,
12-bit digital-to-analog converter (DAC) in an MSOP pack-
age. It includes a rail-to-rail output buffer amplifi er 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 250μA 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
package make the LTC1659 ideal for battery-powered
applications.
