GENERAL DESCRIPTION
The AD5625R/AD5645R/AD5665R, 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 .
The AD5625R/AD5645R/AD5665R have an on-chip reference. The
AD56x5RBCPZ have a 1.25 V, 5 ppm/°C reference, giving a full-scale
output range of 2.5 V; the AD56x5RBRUZ 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 AD5665
and AD5625 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 or midscale 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 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 AD5625R/AD5645R/AD5665R, AD5625/AD5665 use a 2-
wire I2C-compatible serial interface that operates in standard
(100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes.
