Texas Instruments Instrumentation Amplifier 1 mV Offset 550 kHz, 1 Channel, 8-Pin SOIC, 3V-5.5V Supply INA155UA

Texas Instruments INA155UA instrumentation amplifier is a single-channel, high precision device designed for amplifying the difference between two input signals while rejecting common-mode noise. The amplifier operates with a supply voltage range of 3 V to 5.5 V and features a low input offset voltage of 1 mV, making it ideal for sensitive measurement applications. Its gain bandwidth product of 550 kHz allows for fast signal response in electronic circuits.

This 8-pin SOIC surface mount amplifier draws only 2.1 mA supply current, making it suitable for power-sensitive designs. It offers a common mode rejection ratio of 80 dB, enhancing its performance in electrically noisy environments such as industrial instrumentation, medical devices, and test equipment. The device can operate reliably across a wide temperature range of -65°C to 150°C, supporting use in harsh and demanding conditions.

The INA155UA employs a classic three operational amplifier configuration to provide high input impedance and precise gain control via internal or external resistors. Its low offset and noise characteristics make it well suited for laboratory instrumentation, industrial monitoring, and precision sensor signal conditioning.

Applications include industrial automation, medical instrumentation, and precision testing where accurate differential signal amplification is critical. The compact SOIC package eases integration into complex PCB layouts.

The 1 mV input offset voltage ensures minimal signal distortion. Wide supply voltage (3 V to 5.5 V) supports diverse systems. High 550 kHz gain bandwidth enables rapid signal processing. 8-pin SOIC package allows for space-efficient mounting.
