The DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed 12-bit monotonicity performance over the industrial temperature range. It requires a single +5V supply and contains an input shift register, latch, 2.435V reference, a dual DAC, and high speed rail-to-rail output amplifiers. For a full-scale step, each output will settle to 1 LSB within 7μs while only consuming 3.7mW.
The synchronous serial interface is compatible with a wide variety of DSPs and microcontrollers. Clock (CLK), Serial Data In (SDI), Chip Select (CS) and Load DACs (LOADDACS) comprise the serial interface.
The DAC7612 is available in an 8-lead SOIC package and is fully specified over the industrial temperature range of ?40°C to +85°C.
