.DThe 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
wswing 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
wcompatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
mThe reference for AD5601/AD5611/AD5621 is derived from the power
w osupply inputs and thus gives the widest dynamic output range. The part
.cincorporates 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
Upart contains a power-down feature that reduces the current consumption
t4of the device to <100 nA at 3 V and provides software selectable output
eloads while in power-down mode. The part is put into power-down mode
eover the serial interface. The low power consumption of this part in normal
hoperation makes it ideally suited to portable battery operated equipment.
