SBOS776C March 2016 – March 2021 INA3221-Q1
PRODUCTION DATA
To communicate with the INA3221-Q1, the master must first address slave devices with a slave address byte. This byte consists of seven address bits and a direction bit to indicate whether the intended action is a read or write operation.
The INA3221-Q1 has one address pin, A0. Table 8-1 describes the pin logic levels for each of the four possible addresses. The state of the A0 pin is sampled on every bus communication and must be set before any activity on the interface occurs.
A0 | SLAVE ADDRESS |
---|---|
GND | 1000000 |
VS | 1000001 |
SDA | 1000010 |
SCL | 1000011 |
