Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

LT1884CN8#PBF is an advanced low power instrumenation amplifier with a high open-loop gain, low offset and low input current. Its advanced design makes it suitable for multiple applications such asBuffer amplifier, instrumentation amplifier, and current feedback amplifier.

Buffer Amplifier

Buffer amplifiers are widely used to provide a direct interface between low-impedance signals such as from digital devices (microcontrollers, computers) and high-impedance signals from resistive and capacitive sensors. The LT1884CN8#PBF buffer amplifier offers superior stability, input offset current, noise, and frequency response as compared to traditional operational amplifier buffer amplifiers.

Instrumentation Amplifier

Instrumentation amplifiers are ideal for signals with low-level added noise, and allow them to be amplified with minimal distortion and no increase in the noise level. The LT1884CN8#PBF instrumentation amplifier provides excellent low level noise performance and low input offset voltage with wide bandwidth which is ideally suited for sensors and high-frequency signal processing.

Current Feedback Amplifier

Current feedback amplifiers are ideal for applications that require high slew rate such as driving large capacitive loads or high speed signal transmission. The LT1884CN8#PBF current feedback amplifier provides high speed with more linearresponse in a small package.

Working Principle

The LT1884CN8#PBF is based on a voltage-feedback topology. It contains two independent, high-gain, low-voltage-offset amplifiers, each with its own separate power supply connection. Inputs and outputs are connected to both amplifiers,and supplied with voltage references used in setting the gain. The input signal is buffered by the operational amplifier, and then passed to the gain stage. The gain setting for each amplifier is set separately by the voltage reference connected to the appropriate pin. The gain at each stage develops an outputvoltage which is then passed to the output of the device. The LT1884CN8#PBF have several features that include low power consumption, excellent input-referred noise andover-temperature protection. Its low input bias current and low offset voltage allows it to be used in low common mode applications, providing excellent performance in a wide range of applications.

Conclusion

The LT1884CN8#PBF is an advanced low-power instrumentation amplifier with a high open-loop gain, low offset and low input current, designed to provide excellent performance in a wide range of applications. Its advancedfeatures make it ideal for use in applications such as buffer amplifier, instrumentation amplifier, and current feedback amplifier.
