The LMC6484AIM is a low-input bias current, low-offset voltage, dual CMOS operational amplifier. It is designed for single and dual supplies, and features rail-to-rail input and output capabilities, as well as low-frequency compensation. As it is dual, two amplifiers are included in one package, making it suitable for a variety of applications like active filtering, or instrumentation and precision amplifiers. It is designed to provide excellent DC precision and low noise performance, and can handle both audio and DC signals.

Application Field

The LMC6484AIM is suitable for a variety of applications, such as active filters, instrumentation amplifiers and precision amplifiers. It can also be used in audio, video, and instrumentation applications, including systems like audio equalization, multi-media audio systems, and high-precision, tight-tolerance test and measurement instruments. With its rail-to-rail input and output capabilities, the amplifier is capable of pushing more output power than its specs might lead you to believe. This makes it well suited for applications that require high levels of output.

Operation Principle

The operation principle of the LMC6484AIM is based on a high-impedance amplifier stage followed by a low-impedance output stage. The amplifier stage is designed using two combined sections with two identical amplifiers. The first section is configured for a high voltage gain and an AC compensation network at its output. The second section is configured for a high current gain and an AC compensation network at its input. The output stage is designed with an output driver capable of driving both small and large loads. This output stage is capable of providing high output swing and excellent common-mode rejection. The amplifier also features a rail-to-rail input and output capability, meaning that it can accept an input signal and output a signal that matches the incoming signal. This makes it perfect for applications that require maximum levels of output.

The LMC6484AIM is well-suited for applications in the field of instrumentation and precision amplifier systems. Its small size and low input bias current capabilities make it a great choice for applications that require an amplifier with low noise and good performance. Its low-offset voltage capabilities ensure that the amplifier provides accurate results with minimal distortion. With its rail-to-rail input and output capabilities and low noise, the amplifier is sure to provide excellent performance in a variety of applications.
