EL5371IU Application Field and Working Principle

Linear amplifiers, instrumentation amplifiers, OP amps, and buffer amps are essential components in signal and power conditioning circuits. The EL5371IU is a single channel, low-power, unity-gain instrumentation amplifier that leverages a combination of modern design and performance to overcome the limitations often experienced in traditional instrumentation amplifiers. It offers unmatched performance and flexibility for a wide range of signal-processing applications.

Features

The EL5371IU has several industry-leading performance capabilities. Included are a low power consumption (typically less than 10 mW, depending on the loads used); wide common mode voltage range of 0V to 6V; maximum offset voltage of 0.5 mV; and common-mode rejection ratio (CMRR) of up to 100 dB. The part also features an input offset voltage range of 0V to 6V and a low input bias current of 30 pA.

Advantages

The EL5371IU offers several advantages. It can be used with a wide range of input signals, including single-ended, differential, and potentiometric signals. It also provides excellent thermal stability, low noise, and high dynamic range. In addition, the EL5371IU can be used to amplify highly-dynamic signals with fast rise and fall times.

Applications

The EL5371IU is suitable for a range of applications, including medical, industrial, and automotive. It can be used in applications such as pressure sensors, strain gauges, force measurement, DC and AC voltage measurement, and thermal imaging. Additionally, it can be used as an amplifier for thermocouple, RTD, and LVDTs. In automotive applications, it can be used to measure power, torque, and brake force.

Working Principle

The EL5371IU is a single, low-power, unity-gain instrumentation amplifier. It is based on an internally temperature-compensated differential input stage and a fixed gain feedback amplifier. The differential input stage uses precision amplifiers to accurately measure the differential voltage between the inputs and amplify it by a gain of one. The gain of the feedback amplifier is then adjusted by a single external resistor. The output stage is a precision, high-speed amplifier with an output impedance of less than 1 Ohm.

The EL5371IU provides excellent performance even under harsh environmental conditions. Its CMRR is maintained at a high level even at elevated temperatures. Additionally, the part features a high common mode range and low input voltage offset, making it suitable for use with a wide range of input signals.
