Description

16-bit DACs with internal

reference

GENERAL DESCRIPTION

The AD5624/AD5664, members of the nanoDAC family, are

low power, quad, 12-, 16-bit buffered voltage-out DACs that

operate from a single 2.7 V to 5.5 V supply and are guaranteed

monotonic by design.

The AD5624/AD5664 use a versatile 3-wire serial interface that

operates at clock rates up to 50 MHz, and are compatible with

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

standards.

PRODUCT HIGHLIGHTS

The AD5624/AD5664 require 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

and remains there until a valid write takes place. The parts

contain 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. Relative accuracy: 12 ꢀSBs maximum.

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

ꢀFCSP_WD.

3. ꢀow power, typically consumes 1.32 mW at 3 V and

2.25 mW at 5 V.

4. Maximum settling time of 4.5 ꢁs (AD5624) and 7 ꢁs

The low power consumption of these parts in normal operation

makes them ideally suited to portable battery-operated

equipment. The power consumption is 2.25 mW at 5 V, going

down to 2.4 μW in power-down mode.

(AD5664).

The AD5624/AD5664 on-chip precision output amplifier allows

rail-to-rail output swing to be achieved.
