The MCP6022T-E/SN is a dual, low-power, rail-to-rail operational amplifier specifically designed to extend battery life in portable applications to increase the life of devices. It is part of the MCP60XXT-E/SN family of amplifiers and falls under the Linear -Amplifiers - Instrumentation, OP Amps, Buffer Amps category. The device is ideal for applications such as low power audio, battery management, low side current sensing, and micropower data conversion.

The amplifier features rail-to-rail operation for both the input and output and features low quiescent current to extend battery life. The common-mode range for the device extends down into the negative rail so it is highly suitable for single-supply operation. The MCP6022T-E/SN also includes high common-mode rejection and power-supply rejection in order to reduce common-mode voltage noise on the input signal.

The amplifier also has a shutdown mode that can be activated via the logic inputs, which shuts down the bias current to below 0.1 uA. This feature is ideal for battery or power-sensitive applications where a minimum amount of power is being consumed. This same mode can be used to turn the MCP6022T-E/SN into a low-power comparator.

As mentioned, the MCP6022T-E/SN is part of the MCP60XXT-E/SN family of amplifiers. This family of amplifiers includes the MCP6001T-E/SN, MCP6011T-E/SN, and the MCP6021T-E/SN. Each of the amplifiers within this family has its own unique features, but all of them have been designed with low power and excellent noise immunity in mind. This makes them perfect for power and portability-sensitive applications.

The MCP6022T-E/SN’s working principle is based on the basic operational amplifier design, where the input signal is amplified by a resistor and capacitor network. The amplifier is powered by a dual supply, typically called a ± VDD supply. The two supply voltages are symmetrical, meaning both are equal in magnitude but opposite in sign. This allows the true output to swing both positive and negative relative to ground.

The input parameters of the amplifier are also important and consist of the inverting and non-inverting inputs. The inverting input is compared with the non-inverting input and, depending on which input is larger, the output will vary. In this way, the output can be increased or decreased by the variability in the input parameters. The output of the amplifier is then determined by the ratio of the feedback and input resistors, which can vary from 0.1K to 1M depending on the application.

The MCP6022T-E/SN is an ideal companion for battery-powered or power-sensitive projects. Its low power consumption, rail-to-rail operation, and capability of being turned into a low-power comparator make it a great addition to any system. When matched with other components of the MCP60XXT-E/SN family, the MCP6022T-E/SN is sure to be an integral part of any application that requires low power, excellent noise immunity, and rail-to-rail performance.
