The LM2902D is an operational amplifier that belongs to the family of linear amplifiers and instrumentation, OP amps, buffer amps, etc. It is designed to be a low-noise, low-power amplifier module with high speed and stability. The LM2902D is used in applications such as audio amplifiers, motor control circuits, voltage-to-frequency converters, AC amplifiers and more.

The main feature of the LM2902D is its high speed. The output switching time of the LM2902D is typically 30 ns. This makes the module suitable for high-speed applications such as audio and video amplifiers, analog to digital converters, A/D converters, pulse-code modulation systems, PLLs and other applications where fast and accurate operation is required.

The working principle of the LM2902D is based on the classic differential amplifier topology. The amplifier module consists of two differential amplifiers connected in parallel. The inputs of each amplifier are the inverting (VIN-) and non-inverting (VIN+) pins. The output of each amplifier is then combined at the output of the module, which is connected to the OUT pin.

The LM2902D is powered by a dual supply voltage of ±5V, with a quiescent current of 2.5mA. The module also features a low input bias current of 5nA, a high common mode rejection ratio (CMRR) of 100dB and a high output impedance of 10kΩ.

The LM2902D has proven to be an extremely reliable and effective operational amplifier module for a wide variety of applications. Its low current consumption, fast switching time, low power dissipation and high-precision performance make it an ideal solution for high-speed, low-power applications.
