Questions answered in Actions manuals
What communication interface does the ATT7026A use?
The chip provides an SPI interface for transferring measurement data and calibration parameters between the ATT7026A and an external MCU.
How can the ATT7026A be calibrated?
Calibration can be performed either with a hardware resistor‑network method or a software method that uses calibration registers to adjust gain and phase.
What is the supply voltage range for the ATT7022B?
The chip operates with a VCC supply voltage between 4.75 V and 5.25 V.
How can the chip be reset via the SPI interface?
A software reset is performed by writing the command 0xD3 to the SPI port, which triggers a reset of the ATT7022B.
