LT1125CN#PBF is a popular instrumentation amplifier that is used in many applications. It is an active two-stage differential amplifier commonly used in signal conditioning and other instrumentation applications. It offers excellent performance at low power with ±1.2V to±18V dual rail supply voltage.

The LT1125CN#PBF is a very simple device consisting of two op-amps connected together in a differential amplifier configuration. The first op-amp is a unity gain differential amplifier, while the second one is a non-inverting compensated amplifier. The outputs from the two stages are then combined together and fed to the output. The LT1125CN#PBF also has a feedback resistor connected from the output to the negative input of the first op-amp. This feedback provides for improved common-mode rejection ratio (CMRR) and better linearity over a range of supply voltages.

The LT1125CN#PBF has several features that make it ideal for use in instrumentation applications. First, its low noise and low offset voltage makes it suitable for low level signal measurements. Second, its wide common-mode input range eliminates the need for level shifting when working with multiple signals. Third, its low power consumption makes it suitable for portable instrumentation applications. Finally, its excellent power supply rejection ratio (PSRR) makes it suitable for single supply operation.

As with any application, there are some design considerations when using the LT1125CN#PBF. One important factor is the bandwidth of the device. The bandwidth of the LT1125CN#PBF is typically limited to 10MHz, so it may not be suitable for high frequency applications. Additionally, the device does not offer very high common mode rejection and input bias current, so it should be used with signals that have low levels of noise and are not susceptible to large levels of interference.

The LT1125CN#PBF is an excellent choice for many instrumentation applications. Its wide common mode input range, low power consumption, and excellent power supply rejection ratio make it a great choice for portable instrumentation applications. Its low noise and offset voltage allow it to be used in low level signal conditioning applications. And its low bandwidth limits its use to low frequency applications. With its features and advantages, the LT1125CN#PBF is a great choice for any instrumentation application.
