12-Bit Serial Input Digital-to-Analog Converter

Description:
The DAC7611 is a 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, DAC, and high speed rail-to-rail output amplifier. For a full-scale step, the output will settle to 1 LSB within 7ms. The device consumes 2.5mW (0.5mA at 5V). The synchronous serial interface is compatible with a wide variety of DSPs and microcontrollers. Clock (CLK), serial data in (SDI), and load strobe (LD) comprise the serial interface. In addition, two control pins provide a chip select (CS) function and an asynchronous clear (CLR) input. The CLR input can be used to ensure that the DAC7611 output is 0V on power up or as required by the application. The DAC7611 is available in an 8-lead SOIC or 8-pin plastic DIP package and is fully specified over the industrial temperature range of -40°C to +85°C.
