Product Details
●The AD5310R/AD5311R, members of the _nano_DAC™ 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 reset circuit that ensures that the DAC output powers up to zeroscale and remains there until a valid write takes place. The device contains a power-down feature that reduces the current consumption of the device to 2 μA at 5 V while in power-down mode.
●The AD5310R/AD5311R use a versatile SPI or I2C interface, including an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.
