LTC1669IMS8#PBF

LTC1669 is a 10bit voltage output DAC with true buffered rail-to-rail output voltage capability. The reference for the DAC is selectable between the supply voltage or an internal bandgap reference. Selecting the internal bandgap reference will set the full-scale output voltage range to 2.5V. Selecting the supply as the reference sets the output voltage range to the supply voltage. It features a simple 2-wire serial interface compatible with I²C that allows communication between many devices. The internal data registers are double buffered to allow for simultaneous update of several devices at once. The DAC can be put in low current power-down mode for use in power conscious systems. It is used in applications such as digital calibration, offset/gain adjustment, industrial process control, automatic test equipment, arbitrary function generators, battery-powered data conversion products.
