GENERAL DESCRIPTION

SDA

The AD5625R/AD5645R/AD5665R and AD5625/AD5665

members of the nanoDAC® family are low power, quad, 12-/

14-/16-bit, buffered voltage-out DACs with/without an 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.

Figure 2. AD5625/AD5665

The AD5625R/AD5645R/AD5665R have an on-chip reference. The

LFCSP versions of the AD56x5R have a 1.25 V or 2.5 V, 10 ppm/°C

reference, giving a full-scale output range of 2.5 V or 5 V; the

TSSOP versions of the AD56x5R have a 2.5 V, 5 ppm/°C refer-

ence, giving a full-scale output range of 5 V. The WLCSP package

has a 1.25 V reference. 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 AD5625/AD5665 require an

external reference voltage to set the output range of the DAC.

The AD56x5R/AD56x5 use a 2-wire I²C-compatible serial

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

and high speed (3.4 MHz) modes.

with/without internal reference

AD5627R/AD5647R/AD5667R,

AD5627/AD5667

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

the DAC output powers up to 0 V (POR = GND) or midscale

(POR = V_DD) and remains there until a valid write occurs. The

on-chip precision output amplifier enables rail-to-rail output swing.
