OPA552FAKTWT Integrated Circuits (ICs)

OPA552FAKTWT Application Field and Working Principle

The OPA552FAKTWT is a 4-amplifier, fully-differential instrumentation amplifier created by Texas Instruments.

This amplifier is categorized into the linear-amplifiers-instrumentation, op amps, and buffers amps family. It features a wide input voltage range of ±25 V with a rail-to-rail output. The OPA552FAKTWT has a common-mode rejection ratio of 80 dB, and a gain bandwidth of 2 MHz for low-noise operation. It also offers a 5-amp output current capability with temperature compensation for operation in high humidity or cold temperature.

Application Field of OPA 552FAKTWT

The OPA552FAKTWT has been designed for low-signal instrumentation applications which requires a low noise, high gain and high precision. Its rail-to-rail output and wide input voltage range make it suitable for use in signal conditioning, signal processing, and power supply regulation. It is also ideal for applications in highly demanding environment such as medical and industrial.

Its applications includes data acquisition system, bridge-based instrumentation amplifier, PID controllers, strain-gauge amplifiers etc. It is also used extensively in test and measurement equipment, reversing applications and precision sensing.

Working Principle of OPA 552FAKTWT

The OPA552FAKTWT operates as a buffered, differential instrumentation amplifier with adjustable gain. It amplifies one input signal, referred to as the non-inverting input, while the other input signal, referred to as the inverting input, is used to adjust the gain of the non-inverting input. When the output is the same as the input, the gain can be calculated as the ratio of the output voltage to the input voltage.

The OPA552FAKTWT operates by employing four-independent amplifiers. The first and second amplifier buffers the input signal and provides a constant gain across the frequency range. The third amplifier functions as a buffer to set the output of the fourth amplifier. The fourth amplifier forms a unity-gain buffer, which passes the output signal to the output of the device. This circuitry configuration helps provides a wide bandwidth, low power consumption and excellent gain accuracy.
