Application Field
The INA129SHKJ is ideal for low-level, low-noise sensor amplifiers. It operates from a single supply voltage of up to 18 V and can accommodate voltage signals up to ±15 V. It offers excellent DC performance, including low offset and low 1/f noise. This makes it an ideal choice for applications such as medical and laboratory instrumentation, temperature and pressure sensors, and AC powered operating machinery.
The INA129SHKJ is also well suited for high-side pressure, current, and strain measurement. It is capable of providing very low-distortion gain and feedback, with the rated INA129SHKJ providing 37.5 dB CMRR and 0.0003% total harmonic distortion.
In addition, the INA129SHKJ\'s zero drift ensures a long-term stable measurement. This makes it a great choice for low-level medical instrumentation and other critical industrial applications.
Working Principle
The INA129SHKJ is a low-noise, high-impedance, low-offset, low-drift, voltage-sensing instrumentation amplifier. It is based on the principles of feedback and Unity Gain Principle, which combine to provide excellent stability, low offset, and good signal-to-noise ratios.
The signal is first fed into the INA129SHKJ\'s differential input and amplified by both positive and negative amplifiers. This provides a differential voltage across the input with respect to the output signal, producing a differential gain. The gain is then adjusted using a variable resistor to achieve the desired level of sensitivity.
The INA129SHKJ has a high degree of open-loop gain, which ensures low distortion and low-noise performance. The gain is also adjustable using the potentiometer, allowing the amplifier to be used in multiple applications.
Finally, the output of the amplifier is further improved by a feedback network that further reduces offset, drift, and distortion. The output impedance of the INA129SHKJ is also low, making it suitable for high-impedance applications.
Conclusion
The INA129SHKJ is a popular choice for low-noise, low-drift instrumentation amplifiers. It is suitable for a range of applications from low-level temperature and pressure sensors, to medical and operating machinery. The INA129SHKJ is based on the principles of feedback and Unity Gain Principle, which combine to provide excellent stability, low offset, and good signal-to-noise ratios. Its zero-drift ensures a long-term stable measurement and makes it ideal for low-level medical instrumentation and other critical industrial applications.
