LM2904M/NOPB Application Field and Working Principle

The LM2904M/NOPB is a high performance dual low-power operational amplifier from Texas Instruments that has been designed to meet the needs of industrial, commercial, and consumer applications. The LM2904M/NOPB operates from a single +5V power supply or dual supplies of ±2.5V to ±4.2V. It offers excellent DC performance, with a 0.1µV/°C input voltage drift, 0.05µV/°C output offset drift, and a maximum input offset voltage of 25µV. The LM2904M/NOPB also has a wide common mode input voltage range and a low 3.2nV/√Hz low power noise voltage density. The device is protected by an input protection network, which allows its use in virtually any application, including portable devices, audio amplifiers, active filters, and instrumentation.

The LM2904M/NOPB is an integrated circuit. It consists of two independent low power low noise operational amplifiers. It also includes a protection network for transient overloads. The LM2904M/NOPB has high power-to-noise ratio, low input offset current, and low input bias current. The LM2904M/NOPB is available in two versions, the LM2904M and the LM2904N. The LM2904M is designed for use with applications with non-inverting inputs, while the LM2904N is designed for use with applications with inverting inputs.

The LM2904M/NOPB application field includes active filters, audio amplifiers, portable devices, and instrumentation. When used in active filters and instrumentation, the LM2904M/NOPB offers low noise, low distortion, and low power consumption. The low 3.2nV/√Hz low noise voltage density makes the device suitable for audio applications. In portable devices and instruments, the LM2904M/NOPB offers excellent protection from transient overloads.

The LM2904M/NOPB’s working principle is based on the basic principles of operational amplifiers (op-amps). An op-amp is an electronic circuit with two inputs, one input being the input signal and the other being the reference voltage. The output voltage of an op-amp is proportional to the difference between the two input voltages. The LM2904M/NOPB utilizes two of the same type of amplifier and uses the differences between the two inputs to form a difference amplifier. The output of the difference amplifier is then processed by the protection network to provide protection from transient overloads.

In summary, the LM2904M/NOPB is a high performance dual low-power operational amplifier from Texas Instruments. It offers excellent DC performance, with a 0.1µV/°C input voltage drift and 0.05µV/°C output offset drift. The LM2904M/NOPB is suitable for applications such as active filters, audio amplifiers, portable devices, and instrumentation. The LM2904M/NOPB’s working principle consists of the basic principles of operational amplifiers, a difference amplifier, and a protection network.
