The INA2180A1IDGKR is a high-performance, dual-channel, bidirectional current-shunt monitor from Texas Instruments (TI). This precision integrated circuit (IC) is designed to accurately measure voltage across shunts at common-mode voltages from -0.3V to +26V, independent of the supply voltage. Packaged in an ultra-small VSSOP-8 (DGK) package, this device is ideal for space-constrained applications that require precise current measurement.

Key Features

• Precision Monitoring: The INA2180A1IDGKR offers two high-accuracy channels with an error of less than 1%, allowing for precise current measurement in a variety of systems.
• Wide Common-Mode Range: Capable of operating over a wide common-mode voltage range, this device is suitable for multiple applications, including those with higher voltage requirements.
• Low Offset: A low voltage offset allows for accurate readings at very low voltage drops across the shunt, making it easier to detect small changes in current.
• High Bandwidth: With a bandwidth of up to 500 kHz, the INA2180A1IDGKR can handle high-speed applications, ensuring current measurements are timely and accurate.
• Supply Voltage: The device operates from a single 2.7V to 5.5V power supply, providing flexibility in various power environments.
