series introduction
The **INA282 Series** is a family of high-precision, bidirectional current-sense amplifiers designed to deliver accurate current measurement in a wide range of applications. These amplifiers are engineered to provide exceptional performance, combining low offset voltage, high common-mode rejection ratio (CMRR), and a wide input voltage range, making them ideal for monitoring current in both low-side and high-side configurations. With their robust design and advanced features, the INA282 Series is a reliable solution for applications requiring precise current sensing and monitoring.
One of the key features of the INA282 Series is its ability to measure bidirectional current flow, enabling it to handle both positive and negative current signals with equal precision. This is achieved through its integrated differential input architecture, which supports a wide common-mode voltage range, typically from -16V to +80V. This flexibility allows the INA282 to be used in a variety of circuit configurations, including battery management systems, motor control, and power supply monitoring. Additionally, the series offers a high gain accuracy of ±0.5% and a low offset voltage of ±35µV (max), ensuring reliable and accurate current measurements even in demanding environments.
The INA282 Series is designed with a focus on ease of use and integration. It features a fixed gain of 20 V/V, which simplifies circuit design and reduces the need for external components. The amplifiers are available in compact packages, making them suitable for space-constrained applications such as portable electronics, IoT devices, and automotive systems. Furthermore, the series is optimized for low power consumption, making it an excellent choice for battery-powered applications where energy efficiency is critical.
Typical applications for the INA282 Series include overcurrent protection, load monitoring, and energy management in industrial automation, renewable energy systems, and consumer electronics. Its ability to operate reliably in harsh environments, combined with its high accuracy and versatility, makes it a preferred choice for engineers designing systems that require precise current sensing. Whether used in electric vehicles, robotics, or smart home devices, the INA282 Series delivers consistent performance and reliability, ensuring optimal operation across a wide range of use cases.
