TIINA226AQDGSRQ1
Overview
The INA226AQDGSRQ1 is an automotive-qualified, high-accuracy current and power monitor with an I2C and SMBus compatible interface. It features a 16-bit ADC to measure shunt voltage drops and bus supply voltages ranging from 0V to 36V, providing calculated power and current readings directly to the host controller.
Why Choose This Part
This device offers exceptional precision with a 0.1% maximum gain error and a low 10 microvolt offset, allowing for accurate measurements even with small shunt resistors. The AEC-Q100 qualification and functional safety-capable rating make it suitable for rigorous automotive and mission-critical industrial environments.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the INA226EVM evaluation module along with the TI GUI software for rapid prototyping. The 16 programmable I2C addresses allow multiple monitors to reside on the same bus, and integration requires only a standard I2C driver and a calibrated shunt resistor.
