Instrumentation, OP Amps, Buffer Amps --- EL8103IW-T7 Application Field and Working Principle

Instrumentation is a field of electrical engineering focused on the design of instruments and measurements. Traditional instrumentation includes the amplifiers, meters, oscillators and filters. Modern instrumentation involves the use of digital sensors, analog-to-digital converters (ADCs) and digital signal processors (DSPs). EL8103IW-T7 is one of the instrumentation amplifier with good precision, high performing and high stability.

EL8103IW-T7 Application Field

The EL8103IW-T7 is a 3-channel precision differential input instrumentation amplifier. Its purpose is to amplifies and filters small differential signals of Low-Frequency (LF) and High-Frequency (HF) without offset errors, like temperature sensors, bridge sensors, and other small dynamic signals. EL8103IW-T7 are used in a variety of applications including medical, aerospace, industrial and automotive systems. It makes it the ideal choice for medical applications like continuous glucose monitoring (CGM), body temperature sensors, electroencephalography (EEG), pulse oximeters, cardiac output monitors and more.

The EL8103IW-T7 are also used in aerospace applications, such as navigation systems, autopilot systems, and navigation radios, as well as in industrial applications such as process control, electrical power and heat generation and conversion, and building security.

In the automotive industry, the EL8103IW-T7 can be used for engine control, electric power steering, active suspension and active body control, instrument cluster, and infotainment systems.

EL8103IW-T7 Working Principle

EL8103IW-T7 acts as an amplifier, where the input capacitor acts as a low pass filter, allowing the low-frequency signal to pass through and rejecting the high-frequency noise. It also acts as a differential amplifer, where two input ports are connected to the source and the other port is connected to the ground. The output port will be the amplified signal.

The EL8103IW-T7 consists of an operational amplifier (Op-Amp) that is part of an inverting amplifier configuration, an output amplifier, a feedback resistor, and input bias and offset resistors. The operational amplifier (Op-Amp) amplifies the input signal and the output amplifier drives the load and provides the necessary feedback signals. The feedback resistor provides negative feedback to the Op-Amp to ensure accurate signal amplification.

The EL8103IW-T7 also includes two input bias and offset resistors to provide the necessary bias for the amplifier circuit. The input resistors are used to set up the offset voltage of the amplifier and the output resistor helps to maintain the accuracy of the signal.

The EL8103IW-T7 is an excellent choice for applications where accuracy and stability are key requirements. Its high precision and low noise makes it ideal for temperature sensors, bridge sensors, and other small dynamic signals.
