LTC1663 - 10-Bit Rail-to-Rail Micropower DAC with 2-Wire Interface

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.
