EL5157IW-T7 is a high performance, low noise current feedback instrumentation amplifier. It is uniquely designed for measurements in laboratory and industrial settings. The EL5157IW-T7 operates from a single power supply, and provides high common mode rejection ratio (CMRR), low-noise, offset voltage, and band gain. It is highly suitable for engineering test and measurement applications because of its wide range of available output voltages, input impedance, and adjustable gain from 0 to 5 V/V.

The EL5157IW-T7 belongs to the category of linear amplifiers – instrumentation, operational amplifiers, buffer amplifiers. It has a wide band of applications; the most common are in the field of test and measurement, medical technology and process control. The EL5157IW-T7 can be used to measure: strain, temperature, flow, pressure and power levels, as well as chemical, electrical and optical signals.

The EL5157IW-T7 operates on a single voltage supply, requiring no external components and avoiding thermal drift with temperature changes. It features low offset voltage, low noise, low distortion, and a wide slew rate. This makes it an ideal choice for high performance applications, such as measuring and acquiring signals in a noisy environment, for example. It is also very small in size, allowing for more compact board physical solutions.

EL5157IW-T7’s working principle is simple and straightforward. This amplifier contains two main components, the instrumentation amplifier and the amplification stage, each feature designed for a specific purpose. The instrumentation amplifier is designed for precise gain and output level matching, while the amplification stage compensates for resistive and capacitive components in the signal.

The EL5157IW-T7’s instrumentation amplifier consists of two independent, identical amplifier stages. Each stage is composed of a matched current feedback practice, isolating input noise from the output. This allows accurate gain control, resulting in high CMRR and low distortion. The amplification stage features two pairs of transistors, which adjust the signal’s gain. The EL5157IW-T7 also features an adjustable resistor between the two stages to set the frequency response.

Additionally, the EL5157IW-T7 is highly tolerant of power supply changes and thermal drift, providing greater accuracy during changes in environmental conditions. This amplifier also features a slew rate of up to 5 V/µs and is suitable for high-speed digitization in an industrial setting. Furthermore, the EL5157IW-T7’s low-noise design allows for a more accurate representation of the signal, and its low distortion reduces the effects of aliasing errors.

In summary, the EL5157IW-T7 is an ideal choice of amplifier for industrial and laboratory applications. It features a low noise, high CMRR and wide frequency range, making it suitable for high performance applications in medical, measurement, and process control. It is also highly tolerant to power supply and thermal drifts, allowing for more accurate measurements. Overall, the EL5157IW-T7 is a reliable and easy to use amplifier for any engineer or technician.
