LTC1659 - 12-Bit Rail-to-Rail Micropower DAC in MSOP Package

The LTC1659 is a single supply, rail-to-rail voltage output, 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 VCC which can range from 2.7V to 5.5V. This allows a rail-to-rail output swing from 0V to VCC. 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.
