INA232 in INA219 / INA226 Current Sensors Family
The INA232 family by Texas Instruments is a collection of ultra-precise, digital power monitors featuring an integrated 16-bit ADC. Designed to measure shunt voltage, bus voltage, and calculated power, these components interface via I2C or SMBus. They are engineered for high-side or low-side sensing in systems with bus voltages up to 48V. This family serves as a cost-effective yet high-resolution alternative to the legacy INA219, offering improved offset voltage and integrated power computation to reduce host processor overhead.

Variants within the INA232 sub-family primarily differ by their initial accuracy specifications and operating temperature ratings. For example, the 'A' and 'B' grade variants distinguish between different maximum offset voltage limits and gain error specifications. Package options also vary between TSOT-23 and VSSOP, allowing engineers to choose between the smallest possible footprint or standard industrial footprints for ease of manufacturing and thermal dissipation.
