Working Principle

The main component of the INA826AIDRGT is the amplifier. The amplifier is composed of two differential pairs, a P-type MOSFET and an N-type MOSFET. Each of these transistors works in a common-gate configuration and acts as a voltage-controlled voltage source. The input signal is then amplified through the use of the FET’s transconductance properties. The input signal is amplified several hundred times in order to achieve a high gain. Additionally, the transconductance of the FETs allows for very wide input signal signal dynamic range. The output of the amplifier is then further conditioned and filtered by a low-noise wideband operational amplifier, to ensure signal transmission and noise rejection.
