Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps is a product type category that generally covers amplifiers of various forms. Within this category falls EL5306ISZ-T7, an instrumentation amplifier type specifically designed for use with bridge sensor circuits. To understand its application field and working principle, we must first understand its construction and features.

EL5306ISZ-T7 is an integrated circuit that consists of two low noise, low distortion differential amplifiers, programmable gain amplifier and an output amplifier, making it a complete instrumentation amplifier. It has high common mode rejection ratio (CMRR) up to 118 dB and low offset voltage up to 8 uV, making it suitable even for low voltage level applications. On the inputs, it has a low input bias current of 2 pA, and an input impedance of 200 GΩ which translates to a wide bandwidth of DC to 60 kHz. This makes EL5306ISZ-T7 suitable for use as an amplifier for signals from almost any source.

Now that we know the construction and features of EL5306ISZ-T7, let us look at its application fields and working principle. As per the mentioned features, EL5306ISZ-T7 can be used in applications involving the amplification of low level signals such as those obtained from bridge sensors used in a variety of applications in the field of medical science and industrial process control. Its low input bias current enables it to accurately amplify signals without being compromised by any external noise. Its high common mode rejection ratio allows it to discriminate between the input signals and prevent any distortion due to interference from external noise.

The working principle of EL5306ISZ-T7 is based on the concept of differential amplifier. A differential amplifier is a simple device with two inputs and one output, the difference between its input signals is amplified and presented at its output. In the case of EL5306ISZ-T7, two low noise, low distortion differential amplifiers are used along with the programmable gain amplifier and the output amplifier to produce amplified signal with low offset and high CMRR. The signal from the bridge sensor is sent to the bridge sensor and is amplifiend to suit the application\'s signal level, and after being amplified two times, the signal is then presented at the outut.

To sum it up, EL5306ISZ-T7 is a hi-fi instrumentation amplifier that can be used to amplify low level signals obtained from bridge sensors. Its construction consists of two low noise, low distortion differential amplifiers, programmable gain amplifier and an output amplifier which makes it very suitable for applications involving signal amplification. Its features such as low input bias current and high CMRR allows it to accurately and reliably amplify signals without being compromised by any external noise. Its working principle is based on the concept of differential amplifier where the difference between input signals is amplified and presented at the output.
