Finally, it is suitable for data acquisition and other signal processing applications where high accuracy is required.

Working Principle

The LT1498CS8#TRPBF is designed around a differential input stage, with high common-mode rejection ratio. The differential stage amplifies the signal input and the output amplifies the signal between the two stages. It has a wide common-mode range of −2.7V to +11.3V, which helps in rejecting noise. It also has a high input impedance of 10GΩ to further help in noise rejection. The output stage is a transconductor that converts the input differential voltage into current. The gain is adjustable by varying the resistors connected to the GAIN pins. The bias current is also adjustable by connecting a resistor to the BIAS pin.

The LT1498CS8#TRPBF is a highly reliable and accurate instrumentation amplifier. It offers high accuracy, wide bandwidth, and low noise, enabling it to be used in a variety of applications, ranging from signal monitoring to medical imaging. Its differential input stage with high common-mode rejection ratio and adjustable gain and bias current make it even more versatile.
