Description

and 400 kHz operating modes.

36

OPGND

Dedicated Ground Pin for I2C Interface.

37

VDRIVE

This pin should be connected to the supply that the I2C bus is pulled up to. This is not a supply

pin in I2C mode—it just sets up the input threshold levels.

38

DGND

Ground for All Digital Circuitry.

39

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 µF ceramic and 10 µF tantalum capacitors to DGND.

40, 41

ISENSE1 Overrange,

ISENSE2 Overrange

Outputs from Fault Comparators Connected to High-Side Current Sense Amplifiers.

43 to 46

VIN3 to VIN0

Single-Ended Analog Inputs with Input Range from 0 V to REFIN/REFOUT ADC.

47

REFOUT/REFIN ADC

The AD7294 contains REFOUT/REFIN ADC pin for the ADC. 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.

48

DCAP

External Decoupling Capacitor Input for Internal Temperature Sensor. A 0.1 μF capacitor to

AGND should be connected to this pin.

55, 56

VPP1, VPP2

Analog Supply Pins. Power supply pins for the high-side current sense amplifiers. Operating

range is from AVDD to +60 V.
