GENERAL DESCRIPTION

The AD5662, a member of the nanoDAC family, is a low power,

single, 16-bit buffered voltage-out DAC that operates from a

single 2.7 V to 5.5 V supply and is guaranteed monotonic by

design.

The AD5662 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.

PRODUCT HIGHLIGHTS

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 to 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

480 nA at 5 V and provides software-selectable output loads

while in power-down mode.

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

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

3. Low power. Typically consumes 0.42 mW at 3 V and

0.75 mW at 5 V.

4. Power-on reset to zero scale or to midscale.

5. 10 μs max settling time.

The low power consumption of this part in normal operation

makes it ideally suited to portable battery-operated equipment.

The power consumption is 0.75 mW at 5 V, going down to

2.4 μW in power-down mode.

Description

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

rail output swing to be achieved. For remote sensing applications,

the output amplifier’s inverting input is available to the user.
