Working Principle

The LT1114IS#PBF is an instrumentation amplifier based on a three-opamp topology. The input signals are applied to both the inverting and non-inverting inputs through a matched pair of resistors. The differential input voltage is then converted to a single-ended voltage and amplified. The op-amp functions as an buffer between the input and output signals, minimizing the effects of the source and load impedances. The amplifier can be set to provide different gains for finer accuracy and accuracy over temperature. The gain can be set by adjusting the feedback resistance.

The LT1114IS#PBF is a low-drift, low-noise amplifier and has an excellent AC and dynamic response. It can be used for both dc and ac measurements, and has high accuracy and low drift. The amplifier can be used in a variety of applications, from automotive to medical, where high precision and accuracy are desired. The amplifier is designed to have a very wide bandwidth and low noise, and the very low input bias current ensures high performance and low power consumption.
