INA141UA/2K5

The INA141UA/2K5 is a high-precision, high-performance instrumentation amplifier available from Texas Instruments.

The INA141UA/2K5 is a two-channel, low-noise instrumentation amplifier that is ideal for a range of amplified signal needs. Professionals may use the amplifier for data acquisition applications including sound level measurement, electric force measurement, and biomedical signal processing, where accuracy and high-speed response are critical. It also features low noise and distortion, making it an ideal choice for manufacturers of high-end audio equipment.

The INA141UA/2K5 amplifier can be used as a single-ended or differential amplifier, providing versatile functionality for a range of applications. The amplifier\'s input stage consists of two high-precision, low-noise op-amps that are integrated as a single amplifier for increased stability and accuracy. The output stage includes two low noise, high-speed buffer amplifiers. This arrangement results in a high-performance instrumentation amplifier capable of accurate, low-noise amplification of signals over a wide range of frequencies.

The INA141UA/2K5 is an open-loop amplifier that provides high input impedance and low output impedance. Its low input bias current eliminates the need for an external source of current in order to extract more accurate measurements. The amplifier has a gain of up to 200dB and a maximum slew rate of 0.5V/µs with a low distortion level of 0.2 %.

The amplifier can be programmed with an input range between ± 10V to ± 5V for single-ended applications. The differential input range is 0V to ± 5V. The INA141UA/2K5 is capable of driving low and high-impedance loads from its ± 20V to ± 5V output range without the need for external power supply, hence providing a self-contained instrumentation amplifier for a wide range of applications.

The INA141UA/2K5 is suitable for industrial, medical, and consumer applications that require high-precision amplification of signals over a wide range of frequencies. Professionals in medical fields may use the amplifier for electrocardiogram (ECG) monitoring, sound level measurement, vibration measurement, and other biomedical applications. It can also be used in security systems, sound processing, and other data-acquisition systems. Manufacturers of high-end audio products can also use the amplifier for accurate reproduction of sound signals.
