AD5641BKSZ-500RL7

AD5641 is a nanoDAC® family, single, 14bit, buffered, voltage-out DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. This uses a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is compatible with SPI®, QSPI™, MICROWIRE™ and DSP interface standards. The part incorporates a power-on reset circuit, which ensures that the DAC output powers up to 0V and remains there until a valid write to the device takes place. It contains a power-down feature that reduces current consumption typically to 0.2µA at 3V, and provides software-selectable output loads while in power-down mode. The low power consumption of the part in normal operation makes it ideally suited to portable battery-operated equipment. Typical applications are voltage level setting, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators.
