AVDD1 to AVDD5
Analog Supply Pins. These pins should be decoupled with a 0.1 µF ceramic capacitor and a 10 µF
tantalum capacitor. Operating range is 4.5 V to 5.5 V.
5, 6, 12, 21,

AGND 1 to AGND7
Analog Ground Reference Point. All AGND pins should be connected externally to the AGND
plane.

D2(−), D1(−)
Analog Input. Connected to cathodes of the external temperature-sensing diodes.
9, 10
D2(+), D1(+)
Analog Input. Connected to anodes of the external temperature-sensing diodes.

REFOUT/REFIN DAC
The AD7294 contains a REFOUT/REFIN DAC pin common to all four DAC channels. 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.
15, 20, 23, 28
OFFSET IN A to
OFFSET IN D
Used to set the desired output range for each DAC channel. Input range is 0 V to 5 V.
16, 19, 24, 27
VOUT A to VOUT D
Buffered Analog Outputs for DAC Channels A to D. Each analog output is driven by an output
amplifier that can be offset using the offset in pin. DACs provide 12-bit resolution in a 5 V range,
providing an output voltage from 0 V to 15 V. Each output is capable of sourcing and sinking
10 mA and driving a 1,000 pF load.
17, 18
DAC OUT GND AB,
DAC OUT V+ AB
Analog Supply Pins for Output Amplifiers on VOUTA and VOUTB.
25, 26
DAC OUT V+ CD,
DAC OUT GND CD
Analog Supply Pins for Output Amplifiers on VOUTC and VOUTD.
30
ALERT
Digital Output. This pin acts as an out-of-range indicator and becomes active when a conversion
result violates the DATAHIGH or DATALOW register values associated with each channel input.
31 to 33
AS2, AS1, AS0
Logic Inputs. These inputs are used to select unique addresses for the AD7294. Device address
depends on the voltage applied to these pins.
34
SDA
Digital I/O. Serial bus bidirectional data. Open-drain output.
35
SCL
Digital Input. Serial bus clock. The data transfer rate in I2C mode is compatible with both 100 kHz
