Analog Devices AD7391
The AD7390/AD7391 family of 10-bit & 12-bit voltage-output digital-to-analog converters is designed to operate from a single ϩ3 V supply. The full-scale voltage output is determined by the external reference input voltage applied. The rail-to-rail REFIN to DACOUT allows for a full-scale voltage set equal to the positive supply VDD or any value in between.| Part No. | AD7391 |

+3 Volt Serial-Input Micropower 10-Bit & 12-Bit DACs AD7390/AD7391 FUNCTIONAL DIAGRAM AD7390 REF 12-BIT DAC 12 CLR LD EN CLK SDI 12 SERIAL REGISTER DAC REGISTER GND VDD VOUT Built using a CBCMOS process, these monolithic DACs offer the user low cost, and ease-of-use in single-supply ϩ3 V systems. Operation is guaranteed over the supply voltage range of ϩ2.7 V to ϩ5.5 V consuming less than 100 µA making this device ideal for battery operated applications. A doubled-buffered serial-data interface offers high speed, three-wire, SPI and microcontroller compatible inputs using data in (SDI), clock (CLK) and load strobe (LD ) pins.
