GENERAL DESCRIPTION
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 A 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 A at 3 V.

Description
2.7 V to 5.5 V, <100 A, 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.
PRODUCT HIGHLIGHTS
1. Available in 6-lead LFCSP and SC70 packages.
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 A,
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
0.5 V/s.
4. Reference is derived from the power supply.
5. High speed serial interface with clock speeds up to
30 MHz. Designed for very low power consumption.
The interface powers up only during a write cycle.
6. Power-down capability. When powered down, the DAC
typically consumes 0.2 A at 3 V. Power-on reset with
brownout detection.
