Key Featrues
Wide Common-Mode Range (-0.3 V to 26 V): This feature allows the INA199 series to operate in a broad range of common-mode voltages, enabling versatile use in both low-side and high-side current sensing applications. This flexibility enhances its utility in diverse circuits, such as automotive systems, power management, and industrial controls.
Low Offset Voltage (±150 µV Maximum): The low offset voltage minimizes errors in current measurement, particularly when sensing small shunt voltage drops (as low as 10 mV full-scale). This precision is critical for applications requiring accurate current monitoring, such as battery management or overcurrent protection.
Zero-Drift Architecture: The zero-drift design ensures minimal offset and gain drift over temperature (±0.5 µV/°C and ±10 ppm/°C, respectively), providing stable and reliable performance across a wide temperature range (-40°C to 125°C). This is particularly beneficial in environments with fluctuating temperatures.
Multiple Gain Options (50 V/V, 100 V/V, 200 V/V): The availability of three fixed gain options allows users to select the optimal amplification for their specific application, improving measurement accuracy and system optimization. This feature is ideal for precision current sensing in feedback loops or load monitoring.
Low Quiescent Current (100 µA Maximum): The low power consumption of the INA199 series makes it suitable for battery-powered or energy-efficient applications. This feature extends battery life and reduces overall system power consumption, enhancing its use in portable devices and IoT applications.
