Mnemonic
Function
VOUTx
Buffered Analog Outputs for Channel x. Each analog output is driven by a rail-to-rail output amplifier operating at a
gain of 2. Each output is capable of driving an output load of 5 k to ground. Typical output impedance is 0.5 .
SIGNAL_GND(1–5)
Analog Ground Reference Points for Each Group of Eight Output Channels. All SIGNAL_GND pins are tied together
internally and should be connected to the AGND plane as close as possible to the AD5380.
DAC_GND(1–5)
Each group of eight channels contains a DAC_GND pin. This is the ground reference point for the internal 14-bit DAC.
These pins shound be connected to the AGND plane.
AGND(1–5)
Analog Ground Reference Point. Each group of eight channels contains an AGND pin. All AGND pins should be
connected externally to the AGND plane.
AVDD(1–5)
Analog Supply Pins. Each group of eight channels has a separate AVDD pin. These pins are shorted internally and
should be decoupled with a 0.1 F ceramic capacitor and a 10 F tantalum capacitor. Operating range for the
AD5380-5 is 4.5 V to 5.5 V; operating range for the AD5380-3 is 2.7 V to 3.6 V.
DGND
Ground for All Digital Circuitry.
DVDD
Logic Power Supply. Guaranteed operating range is 2.7 V to 5.5 V. It is recommended that these pins be decoupled
with 0.1 F ceramic and 10 F tantalum capacitors to DGND.
REFGND
Ground Reference Point for the Internal Reference.
REFOUT/REFIN
The AD5380 contains a common REFOUT/REFIN pin. When the internal reference is selected, this pin is the reference
output. If the application requires an external reference, it can be applied to this pin and the internal reference can
be disabled via the control register. The default for this pin is a reference input.
