The LM2902KNSR is a monolithic dual operational amplifier designed for general-purpose applications. Providing two independent, high-performance voltage amplifiers, the LM2902KNSR is capable of driving loads of up to 5mA each (8mA total). It features superior performance in terms of accuracy and power dissipation, making it an ideal choice for most analog circuits.

At its core, the LM2902KNSR is a monolithic integrated circuit with two separate amplifier stages. The first stage is a differential, high-gain amplifier, while the second stage is an output buffer. This combination of stages results in an amplifier with excellent accuracy, low distortion, and high output current capability.

The LM2902KNSR offers a slew rate of 100V/us, with a total bias current of 6mA. Its input offset voltage is typically 3mV (with a maximum of 5mV), and its input bias current is typically 10pA. The LM2902KNSR also has an input common-mode voltage range from -0.3V to +16.5V, and an output voltage swing of up to ± 12V.

The LM2902KNSR is designated for instrumentation applications, including signal conditioning, temperature sensing, and waveform generation. It can be used to accurately amplify and level shift low-level signals, such as the signals from strain gauges, thermistors, and optical devices. These outputs can then be used to drive relays, motors, LEDs, and other devices. The LM2902KNSR can also be used in other general-purpose applications, such as analog-to-digital converters.

The LM2902KNSR is designed to operate from a single or dual 5V or ±15V supply. Its power supply current (I_S) is typically 10mA at ±15V. At ± 5V, its power dissipation is typically 12mW.

The LM2902KNSR’s working principle is quite simple. It takes an input, amplifies it using the differential amplifier, and then outputs it using the output buffer. In operation, the two amplifiers work in tandem, allowing an input of up to 1V to be amplified up to an output of up to 5V. This can be done with low noise and low distortion. The LM2902KNSR is an ideal choice for many audio applications.

The LM2902KNSR is a versatile and high-performance linear amplifier that can be used to accurately amplify and level shift low-level signals. With its excellent performance in terms of accuracy and power dissipation, the LM2902KNSR is a great choice for most analog circuits. It is perfect for use in instrumentation applications, such as signal conditioning, temperature sensing, and waveform generation, as well as for general-purpose applications, such as analog-to-digital converters.
