GENERAL DESCRIPTION

The AD5624R/AD5644R/AD5664R, members of the nanoDAC

family, are low power, quad, 12-/14-/16-bit buffered voltage-out

DACs. All devices operate from a single 2.7 V to 5.5 V supply

and are guaranteed monotonic by design.

while in power-down mode. The low power consumption of

this part in normal operation makes it ideally suited to portable

battery-operated equipment.

The AD5624R/AD5644R/AD5664R use a versatile 3-wire serial

interface that operates at clock rates up to 50 MHz, and is

compatible with standard SPI®, QSPI™, MICROWIRE™, and

DSP interface standards. The on-chip precision output amplifier

enables rail-to-rail output swing.

The AD5624R/AD5644R/AD5664R have an on-chip reference.

The AD56x4R-3 has a 1.25 V, 5 ppm/°C reference, giving a full-

scale output range of 2.5 V; the AD56x4R-5 has a 2.5 V,

5 ppm/°C reference giving a full-scale output range of 5 V. The

on-chip reference is off at power-up allowing the use of an

external reference and all devices can be operated from a single

2.7 V to 5.5 V supply. The internal reference is enabled via a

software write.

PRODUCT HIGHLIGHTS

1. Quad 12-/14-/16-bit DACs.

2. On-chip 1.25 V/2.5 V, 5 ppm/°C reference.

The part incorporates a power-on reset circuit that ensures the

DAC output powers up to 0 V and remains there until a valid

write takes place. The part contains a per-channel power-down

feature that reduces the current consumption of the device to

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

3. Available in 10-lead MSOP and 10-lead, 3 mm × 3 mm,

LFCSP_WD.

4. Low power, typically consumes 1.32 mW at 3 V and

2.25 mW at 5 V.
