GENERAL DESCRIPTION
The AD5627R/AD5647R/AD5667R, AD5627/AD5667
members of the nanoDAC family are low power, dual, 12-, 14-,
16-bit buffered voltage-out DACs with/without on-chip
reference. All devices operate from a single 2.7 V to 5.5 V
supply, are guaranteed monotonic by design, and have an I
compatible serial interface.
The AD5627R/AD5647R/AD5667R have an on-chip reference.
The AD56x7RBCPZ have a 1.25 V, 5 ppm/°C reference, giving a
full-scale output range of 2.5 V; the AD56x7RBRMZ have 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. The internal reference is enabled via a
software write. The AD5667 and AD5627 require an external
reference voltage to set the output range of the DAC.
The AD56x7R/AD56x7 incorporate 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

The low power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment.
The on-chip precision output amplifier enables rail-to-rail
output swing.
The AD56x7R/AD56x7 use a 2-wire I
interface that operates in standard (100 kHz), fast (400 kHz),
and high speed (3.4 MHz) modes.
