| Description | The INA280A1IDCKR is a high-precision current sense amplifier designed for high-side current measurement over a wide common-mode voltage range from 2.7V to 120V, making it suitable for industrial and high-voltage applications. It operates with a supply voltage range of 2.7V to 20V and features a fixed gain of 20 V/V, enabling accurate conversion of small shunt voltage drops into measurable output signals. The device offers excellent accuracy with gain error up to ±0.5% and low input offset voltage typically around 15 µV (max ±150 µV), along with low offset drift of ±1 µV/°C . It provides high bandwidth of 1.1 MHz and slew rate of 2 V/µs, allowing fast transient response and real-time current monitoring . The amplifier features high common-mode rejection ratio up to 140 dB and low quiescent current around 370 µA, ensuring efficient operation in precision systems . Operating temperature range is -40°C to +125°C, and the compact SC70-5 package enables space-saving PCB design, making it ideal for power management, motor control, overcurrent protection, and industrial measurement applications. |
