GENERAL DESCRIPTION

The low power consumption of this part in normal operation

makes it ideally suited to portable battery-operated equipment.

The power consumption is 0.7 mW at 5 V, reducing to 1 µW in

power-down mode.

The AD5620/40 parts are a member of the nanoDAC family of

devices. They are low power, single, 12-/14-bit buffered voltage-

out DACs, guaranteed monotonic by design. The AD5620/40x-1

operate from a 3 V single supply featuring an internal reference

of 1.25 V and an internal gain of 2. The AD5620/40x-2/3 operate

from a 5 V single supply featuring an internal reference of 2.5 V

and an internal gain of 2. Each reference has a 10 ppm/°C max

temperature coefficient. The reference associated with each part

is available at the REFOUT pin.

The AD5620/40 is designed with new technology and is the

next generation to the AD53xx family.

RELATED DEVICES

Part No. Description

AD5660 3 V/5 V 16-bit DAC in SOT-23, internal reference

AD5662 2.7 V to 5.5 V 16-bit DAC in SOT-23, external reference

The part incorporates a power-on reset circuit, which ensures

that the DAC output powers up to 0 V (AD5620/40x-1/2) or to

midscale (AD5620/40x-3) and remains there until a valid write

takes place. The part contains a power-down feature that reduces

the current consumption of the device to 200 nA at 5 V and

provides software selectable output loads while in power-down

mode.

PRODUCT HIGHLIGHTS

1. 16-bit DAC; 12-bit accuracy guaranteed.

2. On-chip 1.25 V/2.5 V, 10 ppm/°C max reference.

3. Available in 8-lead SOT-23 and 8-lead MSOP packages.

4. Power-on reset to 0 V or midscale.

5. Power-down capability. When powered down, the DAC

typically consumes 50 nA at 3 V and 200 nA at 5 V.

6. 10 µS settling time.

The AD5620/40 uses a versatile 3-wire serial interface that

operates at clock rates up to 30 MHz and is compatible with

standard SPI™, QSPI™, MICROWIRE™, and DSP interface

standards. Its on-chip precision output amplifier allows rail-to-

rail output swing to be achieved.
