ZHCS766A February 2012 – December 2021 INA230
PRODUCTION DATA
The INA230 uses a bank of registers for holding configuration settings, measurement results, minimum and maximum limits, and status information. Table 8-3 summarizes the INA230 registers; refer to the Section 8.2 for an illustration of the registers.
All 16-bit INA230 registers are two 8-bit bytes through the I2C interface.
