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 μA at 5 V. The parts come in a tiny SC70 package.

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.

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

SYNC

Available in a space-saving, 6-lead SC70 package.

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.

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/μs.

Reference is derived from the power supply.

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.

Power-down capability. When powered down, the DAC

typically consumes 0.2 μA at 3 V. Power-on reset with

brownout detection.
