2. Wide input voltage range (2.5V to 5.5V)
3. High accuracy (±0.5%)
4. Low power consumption (typical 2.5µA in shutdown mode)
5. Programmable gain (1, 10, 20, 40, 80, 160)
6. I2C and SMBus compatible digital interface
7. Wide operating temperature range (-40°C to +125°C)

Applications:

1. Energy harvesting systems
2. Battery monitoring systems
3. Power supplies and power management
4. Solar panel energy measurement
5. Electric vehicle battery management systems
6. UPS systems
7. Telecommunications equipment power monitoring
8. Industrial control systems

The INA300AIDSQR is a versatile and accurate solution for a wide range of applications that require precise current and power measurement. Its low power consumption and small form factor make it ideal for portable and energy-sensitive applications.
