Product Overview: INA2331AIPWT from Texas Instruments

The INA2331AIPWT is a high-precision instrumentation amplifier designed and manufactured by Texas Instruments, a leader in the semiconductor industry. This advanced component is engineered to offer excellent accuracy and low noise performance in a wide range of applications, including medical instrumentation, industrial process controls, and precision data acquisition systems.

The INA2331AIPWT is built with a patented auto-zeroing technique that significantly reduces the offset voltage and drift over time and temperature. This feature ensures stable and reliable measurements even in environments with fluctuating conditions. The device operates over a wide supply range of ±2.25V to ±18V, or +4.5V to +36V, making it versatile for various power supply configurations.

With a high common-mode rejection ratio (CMRR) of 100 dB (typical) and a high open-loop gain, the INA2331AIPWT provides excellent isolation of the signal of interest from unwanted common-mode noise. This makes it particularly useful in applications where signal integrity is paramount.

Furthermore, the INA2331AIPWT features a low total harmonic distortion (THD) and a low input bias current, which makes it suitable for precision amplification of low-level signals. The device is offered in a compact TSSOP-14 package, which is ideal for space-constrained applications.

Key specifications include:

• Low offset voltage: 25 µV (max)
• Offset drift: 0.1 µV/°C (max)
• Low noise: 9 nV/√Hz (at 1 kHz)
• Wide bandwidth: 1.5 MHz (G = 100)
• High CMRR: 100 dB (typical)

With its robust design and high-performance features, the INA2331AIPWT is a reliable choice for demanding precision applications. Whether you're designing a new medical device or upgrading an industrial control system, the INA2331AIPWT from Texas Instruments offers the precision and stability needed to ensure accurate and consistent results.
