Working Principle

MCP6021T-I/ST is a dual operational amplifier. It consists of two independent amplifiers and each amplifier consists of one inverting and one non-inverting input, a single amplifier output and two bias current sources. The two bias current sources are controlled by the external power supply and bias currents can be set by changing the external power supply voltage.

The two input signals are applied to the input of the amplifier and two bias currents are applied to the output of the amplifier. In the inverting input, one of the bias currents mirrors the input signal, while in the non-inverting input, the other bias current reduces the input voltages. This results in the amplification of the input signal, which is then output at the output terminal of the amplifier.

The amplifier gain is determined by the ratio of the input voltage to the output voltage. The internal bias current sources and external power supply are controlled to set the gain of the amplifier.MCP6021T-I/ST also has low supply current and low input bias currents, making it suitable for low-power applications.
