GENERAL DESCRIPTION

The AD5662 parts are a member of the nanoDAC^TMfamily of

devices. They are low power, single, 16-bit buffered voltage-out

DACs. All devices operate from a single 2.7 V to 5.5 V, and are

guaranteed monotonic by design.

The AD5662 is designed with new technology, and is the next

generation to the AD53xx family.

PRODUCT HIGHLIGHTS

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

The AD5662 requires an external reference voltage to set the

output range of the DAC. The part incorporates a power-on-

reset circuit that ensures the DAC output powers up to 0 V

(AD5662x-1) or midscale (AD5662x-2), 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.

2. Available in 8-lead SOT-23 and 8-lead MSOP package.

3. Power-on-reset to zero or midscale.

4. Low power. Operates with 2.7 V to 5.5 V supply. Typically

consumes 0.35 mW at 3 V and 0.7 mW at 5 V, making it

ideal for battery-powered applications.

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

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

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.

6. 10 µs settling time.

Description

The AD5662’s on-chip precision output amplifier allows rail-to-

rail output swing to be achieved. The AD5662 utilizes 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.
