TIINA228EVM
Overview
The INA228EVM is a demonstration platform for the INA228, a 20-bit high-precision digital power monitor with an I2C interface. It allows engineers to evaluate the IC's ability to measure bidirectional shunt current, bus voltage up to 85V, and integrated power, energy, and charge accumulation. The board provides a complete hardware reference for testing the high-side or low-side current sensing capabilities of the ultra-high resolution ADC.
Why Choose This Part
The system offers an extremely high 20-bit resolution with 0.05 percent accuracy, significantly reducing measurement error in low-power or high-precision applications. It includes built-in digital accumulation for energy and charge, which offloads complex math from the host microcontroller while maintaining a low run current of less than 1.1mA.
Applications
Key Specifications
Getting Started
Connect the EVM to a host PC using the included USB cable and use TI's GUI software to configure the INA228 registers and visualize real-time data. External current shunts and bus voltages can be connected via the terminal blocks for rapid prototyping in various system configurations.
