The LMP8480MME-S/NOPB is a precision, high-voltage bidirectional current sense amplifier from Texas Instruments. It is designed to accurately measure current across shunt resistors over a wide range of common-mode voltages. This component is essential for applications requiring current monitoring, such as motor control, battery management, and overcurrent protection systems.

Key Features

• Wide Common-Mode Range: The LMP8480MME-S/NOPB operates over a common-mode voltage range of 4.5V to 76V, making it suitable for high-voltage applications.
• High Accuracy: With an offset voltage of only 250 µV and a gain error of less than 0.75%, this amplifier provides precise current measurements.
• Variable Gain: The device offers a default gain of 20 V/V, which can be adjusted by adding external resistors, providing flexibility for different application requirements.
• Bidirectional Sensing: It is capable of measuring both charge and discharge currents, which is particularly useful for battery-powered applications.
• Low Quiescent Current: The LMP8480MME-S/NOPB has a low quiescent current, thereby reducing power consumption and making it ideal for power-sensitive systems.
• Robust Design: Its robust design includes a -40°C to 125°C operating temperature range and protection features like EMI filtering, which enhance system reliability.
