DescriptionThe AD5601/AD5611/AD5621, members of the
nanoDAC? family, are single, 8-/10-/12-bit, buffered voltage output DACs that operate from a single 2.7 V to 5.5 V supply, consuming typically 75 A at
The AD5601/AD5611/AD5621, members of the nanoDACTM family, are single, 8/10/12-bit buffered voltage out DAC that operates from a single 2.7 V to +5.5 V supply consuming <100 µA at 5 V, and comes in a tiny SC70 package. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5601/AD5611/AD5621 utilizes a versatile 3- wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
The reference for AD5601/AD5611/AD5621 is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on-reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to <100 nA at 3 V and provides software selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment.The combination of small package and low power make these devices idea for level setting requirements such as generating bias or control voltages in space constrained and power sensitive applications
