Application Field:

LMC7101BIM5-TR can be used in many different applications. It can be used in battery-powered instrumentation such as medical or process control systems. It has wide-bandwidth performance and can be used in signal processing applications, including video or RF communication circuits. Its low noise performance makes it suitable for signal conditioning where noise must be kept at a minimum. It also has low power consumption, so it is ideal for applications that require a long battery life. The rail-to-rail output stage and wide operating supply voltage range makes it suitable for a wide range of applications.

Working Principle:

LMC7101BIM5-TR combines a dual-MOSFET amplifier with a bipolar output stage. This allows the device to have a wide frequency response and high input impedance. The wide frequency response is achieved by using a combination of small signal MOSFET devices with high gain bandwidth, while the high input impedance is provided by the hybrid design. The bipolar output stage provides the device with low output noise and a low offset voltage. The rail-to-rail output stage and wide operating supply voltage range allow the device to drive a variety of loads from very small resistances to very large resistances.

To ensure fast response times, the input stage consists of a differential pair of MOSFETs and a high-speed current mirror. The transistors form the differential input which sets up the amplifier gain, and the high-speed current mirror supplies the current for the output stage. The output stage is composed of a pair of complementary bias current sources and a pair of output transistors. This configuration provides the device with rail-to-rail output signals. The low output noise and wide operating supply voltage range allows the device to better handle large signal swings without exceeding its specified limits.
