AD5681RBRMZ-RL7

AD5681RBRMZ-RL7 is a low power, single-channel buffered voltage out digital-to-analogue converter (DAC). The output span can be programmed to be 0V to VREF or 0V to 2 × VREF. All devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. It contains a power-down mode that reduces the current consumption of the device to 2µA (maximum) at 5V and provides software selectable output loads while in power down mode. Some devices also include asynchronous RESET (active high) pin and VLOGIC pin options, allowing 1.8 V compatibility. Application includes process controls, data acquisition systems, digital gain and offset adjustment, programmable voltage sources.
