Texas Instruments Precision Instrumentation Amplifier, 1 mV Input Offset, 550 kHz Gain Bandwidth, 8-Pin SOIC INA155UA

Texas Instruments INA155UA instrumentation amplifier is a high-performance precision amplifier designed for amplification of differential signals while rejecting common-mode noise. The low input offset voltage of 1 mV combined with a gain bandwidth product of 550 kHz and 80 dB common mode rejection ratio makes it ideal for applications requiring accurate signal conditioning in electrically noisy environments.

Packaged in a compact 8-pin SOIC surface mount package, the INA155UA supports a supply voltage range from 3 V to 5.5 V with a low supply current of 2.1 mA, making it suitable for power-sensitive industrial and laboratory equipment. It operates reliably over an extended temperature range from -65°C to 150°C, thereby addressing harsh environmental conditions.

Instrumentation amplifiers like the INA155 series typically use three operational amplifiers inside to deliver high input impedance, low noise, and stability. With a slew rate of 6.5 V/μs, this amplifier can respond quickly to input changes, ensuring fidelity in fast measurement signals.

This model is ideal for diverse industrial, laboratory instrumentation, manufacturing, medical devices, and electrical engineering applications that demand precise amplification with minimal offset and noise interference.
