The 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 μA at 5 V. The parts come in tiny LFCSP and SC70
packages. Their on-chip precision output amplifier allows rail-
to-rail output swing to be achieved. The AD5601/AD5611/
AD5621 utilize 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 the AD5601/AD5611/AD5621 is derived
from the power supply inputs and, therefore, gives the widest
dynamic output range. The parts incorporate a power-on reset
circuit, which ensures that the DAC output powers up to 0 V
and remains there until a valid write to the device takes place.
The AD5601/AD5611/AD5621 contain a power-down feature
that reduces current consumption to typically 0.2 μA at 3 V.

2.7 V to 5.5 V, <100 μA, 14-bit nanoDAC in
SC70 and LFCSP packages
They also provide software-selectable output loads while in
power-down mode. The parts are put into power-down mode
over the serial interface.
The low power consumption of these parts in normal operation
makes them ideally suited to portable battery-operated equip-
ment. The combination of small package and low power makes
these nanoDAC devices ideal for level-setting requirements,
such as generating bias or control voltages in space-constrained
and power-sensitive applications.

2. Low power, single-supply operation. The AD5601/
AD5611/AD5621 operate from a single 2.7 V to 5.5 V
supply with a maximum current consumption of 100 μA,
making them ideal for battery-powered applications.
3. The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a typical slew rate of
