AD5621AKSZ-REEL7

AD5621 is a 12bit buffered voltage output DAC. It utilizes a versatile 3-wire serial interface that operates at clock rates upto 30MHz and is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards. The reference for buffered voltage output DAC is derived from the power supply inputs and, therefore, gives the widest dynamic output range. It also provide software-selectable output loads while in power-down mode. The low power consumption of this parts in normal operation makes them ideally suited to portable battery-operated equipment. The combination of small package and low power makes this nanoDAC device ideal for level-setting requirements, such as generating bias or control voltages in space-constrained and power-sensitive applications. This voltage output DAC is widely used in application such as voltage level setting, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators etc.
