Part Number Description

AD5641

2.7 V to 5.5 V, <100 µA, 14-bit nanoDAC in

SC70 and LFCSP packages

APPLICATIONS

Voltage level setting

Portable battery-powered instruments

Digital gain and offset adjustment

Programmable voltage and current sources

Programmable attenuators

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.

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 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.

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 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

0.5 V/µs.

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 µA at 3 V. Power-on reset with

brownout detection.

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.
