TEXAS INSTRUMENTS Current Sense Amplifier SOT-23 5-Pin

The TEXAS INSTRUMENTS Current Sense Amplifier is a precision, surface-mount integrated circuit designed for accurate current monitoring in a wide array of electronic applications. Featuring a high gain of 100 V/V, it provides excellent signal amplification from small sense voltages, making it ideal for power management, battery monitoring, and overcurrent protection circuits.

This versatile amplifier can be configured for both high-side and low-side current sensing, offering design flexibility. It operates from a single supply voltage ranging from 2.7V to 5.5V, ensuring compatibility with common 3.3V and 5V logic systems. With an impressive Common-Mode Rejection Ratio (CMRR) of 100dB, it effectively minimises noise and maintains accuracy even in electrically noisy environments.

Key performance specifications include a low input offset voltage of just 100µV and a modest input bias current of 80µA, which contribute to high measurement precision and minimal impact on the sensed circuit. The device offers a gain bandwidth product of 150kHz, suitable for a broad range of DC and low-frequency sensing tasks.

Housed in a compact, industry-standard SOT-23 package with 5 pins, it is perfect for space-constrained PCB designs. The amplifier is rated for an extensive operating temperature range from -40°C to +125°C, guaranteeing reliable performance in demanding industrial and automotive conditions.
