A linear amplifier is an amplifier whose amplifying element provides substantial linearity over a wide range of input signals. In other words, it responds to the inputs in proportion to their amplitude and frequency, providing an output that is proportional to the input. That is, the output signals are not distorted by the amplifier, as is the case with a non-linear amplifier. The ONET8551TYS4 is an instrumentation amplifier that is ideal for catering to a wide range of applications and one such application where a linear amplifier is needed is in the field of instruments.

The ONET8551TYS4 linear amplifier is configured as a three-opamp instrumentation amplifier, which is a difference amplifier followed by a high common-mode rejection (CMRR) amplifier. The main advantage to this setup is that it eliminates the need for bulky external trim and matching components, thereby providing a high level of stability over long periods, without the need for additional trimming. Moreover, the amplifier is capable of being programmed for a variety of gains such as 0, 1, 2 or 4 V/V.

The circuit itself is comprised of dual differential (or unbalanced) inputs and an adjustable gain which is set through the external resistor, Rgain. This resistor is connected in the feedback loop, which increases the gain of the instrumentation amplifier and the CMRR of the amplifier by 1 V/V for each 1 Ohm of resistance in the loop. For a maximum gain of 4 V/V, the resistor is set to 4 Ohms. The output of the amplifier is produced at a high impedance node and as such, this amplifier can be used in situations where there are high output impedances present.

Another important feature of the ONET8551TYS4 amplifier is its ability to provide a high level of accuracy. This is achieved through its high CMRR and its operating temperature range of -40°C to 85°C. Moreover, it is also capable of providing low output offset and drift, making it an ideal choice for low-noise applications. It is also capable of sustaining a signal amplitude of up to 36 dB. In addition, the amplifier features an adjustable gain range from 0 to 4 V/V and can be programmed with an adjustable equation to suit a wide range of applications.

When it comes to applications, the ONET8551TYS4 is particularly well-suited for use in test and measurement equipment such as radiometers, signal generation and monitoring systems, pressure transducers, and strain gauges. Furthermore, it is also suitable for use in manufacturing and process control applications, including process indicator controllers and other data acquisition systems.

In conclusion, the ONET8551TYS4 linear amplifier is a highly versatile instrumentation amplifier that is suitable for a variety of applications. Its three-opamp circuit configuration eliminates the need for bulky external components, providing a high level of stability and accuracy. It is capable of providing an adjustable gain range from 0 to 4 V/V and can be programmed with an adjustable equation. Therefore, it is ideal for use in test and measurement equipment, manufacturing and process control applications, and many other applications.
