Product Description
Texas Instruments LMP8603MA/NOPB current sensing amplifier is a precision semiconductor device designed for accurate current and power measurement in real-time system protection, feedback control, and monitoring applications. This amplifier operates on a single power supply ranging from 3V to 5.5V with a low supply current of 1.3mA, making it suitable for low-power embedded and industrial systems.
The device features a single channel with an 8-pin SOIC surface mount package, enabling compact PCB layout. With a common mode rejection ratio (CMRR) of 80dB and temperature range from -40°C to 125°C, it performs reliably in demanding industrial, automotive, and HVAC environments. The gain bandwidth product of 60kHz ensures fidelity in measuring current through voltage outputs proportional to the voltage drop across a very low-value resistor in power rails.
Designed to comply with the AEC-Q100 automotive standard, this amplifier is ideal for circuit protection, power management, and system monitoring applications requiring high accuracy under high current conditions. It simplifies current measurement by providing an analogue output that facilitates integration in power control loops and diagnostic systems.
Typical use cases include industrial motor drives, battery management systems, power supplies, and electronic control units. The surface mount SOIC package and low power characteristic support modern compact and energy-efficient system architectures.
Operates from 3V to 5.5V supply voltage for versatile applications. Low supply current of 1.3mA assists in efficient power consumption. High common mode rejection ratio (80dB) reduces noise interference. Single channel in an 8-pin SOIC package suits small form factor designs.
Wide operating temperature of -40°C to 125°C ensures durability. 60kHz gain bandwidth product supports stable and accurate measurement. AEC-Q100 compliant for automotive-grade reliability. Analogue output proportional to current enables precise sensing.
This current sensing amplifier is a vital component in semiconductor amplification categories and is widely used across electronics, industrial, automotive, and laboratory instrumentation fields.
