GENERAL DESCRIPTION

The AD5620/AD5640/AD5660, members of the nanoDAC™

family of devices, are low power, single, 12-/14-/16-bit, buffered

voltage-out DACs and are guaranteed monotonic by design.

The AD5620/AD5640/AD5660-1 parts include an internal,

1.25 V, 5 ppm/°C reference, giving a full-scale output voltage

range of 2.5 V. The AD5620/AD5640/AD5660-2-3 parts include

an internal, 2.5 V, 5 ppm/°C reference, giving a full-scale output

voltage range of 5 V. The reference associated with each part is

available at the V

The parts incorporate a power-on reset circuit to ensure that the

DAC output powers up to 0 V (AD5620/AD5640/AD5660-1-2)

or midscale (AD5620-3 and AD5660-3) 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. The power consumption is

2.5 mW at 5 V, reducing to 1 μW in power-down mode.

The AD5620/AD5640/AD5660 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. The AD5620/AD5640/AD5660 use

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.
