ADI AD5311RBRMZ-RL7

The AD5310R/AD5311R are low power, single-channel, 10-bit buffered voltage output DACs. The devices include an enabled by default internal 2.5V reference, and provides 2ppm/°C. The output span can be programmed to be 0V to VREF or 0V to 2×VREF. All devices operate from a single 2.7 V to 5.5V supply and are guaranteed monotonic by design. The devices are available in 10-lead MSOP packages. The internal power-on reset circuit of the AD5310R/AD5311R ensures that the DAC register is written to zero scale at powerup when the internal output buffer is configured in normal mode. The devices contain a power-down mode that reduces the current consumption of the device to 2μA at 5V. The AD5310R/AD5311R use a versatile SPI or I²C interface, including an asynchronous RESET pin and a VLOGIC pin that provides 1.8 V compatibility.
