Description

The LTC1663 is a 10-bit voltage output DAC with true buffered rail-to-rail output voltage capability. It operates from a single supply with a range of 2.7V to 5.5V. 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.The part features a simple 2-wire serial interface compatible with SMBus and 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.Power-on reset ensures the DAC output is at 0V when power is initially applied, and all internal registers are cleared.For I2C designs, please refer to the LTC1669.ApplicationsDigital CalibrationOffset/Gain AdjustmentIndustrial Process ControlAutomatic Test EquipmentArbitrary Function GeneratorsBattery-Powered Data Conversion Products
