AD5621BKSZ-REEL7

The AD5621BKSZ-REEL7 is a single 12-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply, consuming typically 75µA at 5V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5601 utilizes 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 reference for the AD5601 is derived from the power supply inputs and therefore, gives the widest dynamic output range. 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 to typically 0.2µA at 3V. It also provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface.
