LM2904ADMR2G

The LM2904ADMR2G is a high-performance operational amplifier designed for an extensive range of signal conditioning and signal control applications. It features two high-impedance inputs and two low-noise outputs, making it ideal for signal conditioning, signal control, and signal routing in instrumentation, audio and video processing systems. The low output resistance and low noise make it suitable for a variety of signal paths.

The LM2904ADMR2G is based on the classic differential amplifier amplifier that has been used in analog signal conditioning applications for many years. The standard design of the amplifier consists of two differential inputs, effectively four discrete transistors arranged in a cross-configured differential pair. This configuration ensures low noise and wide gain bandwidth.

The input is single-ended and fed into a differential pair configuration of two Junctions Field effect Transistors (JFETs) in which one JFET acts as an input stage and the other as a feedback loop. The output of this differential pair is then fed into an external gain-setting resistor and then into a high-gain, low-distortion amplifier that provides a high current output. The output is then fed into a voltage follower buffer that provides a low-drift, low-noise high-speed output.

The LM2904ADMR2G can achieve a wide range of gains, from unity to a maximum of twenty five, making it suitable for a variety of signal conditioning applications. It can be used in instrumentation applications such as potentiometer and thermistor control, thermocouple-voltage conversion, and bridge amplifier circuits. It can also be used in audio applications such as audio preamplifiers and tone controls. In video applications, it is used for DC coupled video preamplifiers and overlays.

The LM2904ADMR2G is also suitable for various power management applications, including lighting dimming and motor speed control. It can also be used in active damping circuits, as well as servo control and robotic control. It is also an excellent choice for piezoelectric control in precision motion control systems. Many other applications make use of the gain and bandwidth capabilities of the LM2904ADMR2G.

The main advantage of the LM2904ADMR2G is its low noise and wide gain bandwidth. It is also highly stable, and typically exhibits less than 0.5% distortion at 10 kHz. It is also wide-bandwidth, making it ideal for high-frequency applications such as audio and video processing. The low output resistance, low noise, and wide gain bandwidth make it suitable for a variety of signal paths.

Overall, the LM2904ADMR2G is an excellent operational amplifier that can be used in many different applications, from instrumentation to audio and video processing. Its wide gain bandwidth and low noise performance makes it ideal for signal conditioning, signal control, and signal routing in instrumentation systems. It is also suitable for a variety of power management and precision motion control applications.
