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 I²C-

compatible serial interface.

software-selectable output loads 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 on-chip precision output amplifier enables rail-to-rail

output swing.

The AD56x7R/AD56x7 use a 2-wire I²C-compatible serial

interface that operates in standard (100 kHz), fast (400 kHz),

and high speed (3.4 MHz) modes.

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
