Description
The LTC™1658 is a single supply, rail-to-rail voltage output, 14-bit digital-to-analog converter (DAC) in an 8-lead MSOP package. It includes an output buffer amplifier and an easy-to-use 3-wire cascadable serial interface. The LTC1658 output swings from 0V to VREF. The REF pin can be tied to Vcc for rail-to-rail output swing. The LTC1658 operates from a single 2.7V to 5.5V supply. The typical power supply current is 270µA. The low power supply current makes the LTC1658 ideal for battery-powered applications. The space saving MSOP provides the smallest 14-bit DAC system available.
