Working Principle of the LT1722IS5#TRPBF

The working principle of the LT1722IS5#TRPBF instrumentation amplifier is based on the concept of differential-ended amplifiers. It is designed to accept two differential-ended input signals and produce a single differential-ended output signal. The signals are amplified by an adjustable gain factor, which can range from 100V/V to 10000V/V. The amplifier also features an adjustable offset voltage, which allows the user to closely set the output voltage of the device to the desired value.

The LT1722IS5#TRPBF is designed to have a high common-mode rejection ratio (CMRR) of 50 dB at 1 kHz. This allows for a much higher level of accuracy when amplifying signals with similar but differing common-mode voltages. The CMRR also prevents unwanted noise signals from external sources from being included in the amplified output signal.

The amplifier also features an excellent noise performance of 0.94 uV rms. This allows the instrumentation amplifier to be used in applications requiring very precise and clean signals. The amplifier has a wide bandwidth of 1 MHz and a high input impedance of 1 GΩ which makes it suitable for amplifying fast signals.
