Description

The AD5310R / AD5311R, members of the nanoDAC™ family, are low power, single-channel, 10-bit buffered voltage-out DACs. The devices include a 2.5 V, 2 ppm/°C internal reference. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in 10-lead MSOP packages.The AD5310R / AD5311R also incorporate a power-on resetcircuit that ensures that the DAC output powers up to zeroscaleand remains there until a valid write takes place. Thedevice contains a power-down feature that reduces the currentconsumption of the device to 2 μA at 5 V while in power-downmode.The AD5310R / AD5311R use a versatile SPI or I2C interface,including an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.PRODUCT HIGHLIGHTS High Relative Accuracy (INL): ±0.5 LSB maximum. Low Drift 2.5 V On-Chip Reference: 5 ppm/°C maximum temperature coefficient.APPLICATIONS Process controls Data acquisition systems Digital gain and offset adjustment Programmable voltage sources Optical modules
