Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The LM2904WHD is a type of linear amplifier such as instrumentation amplifier (in-amp), operational amplifiers (op-amps), and differential amplifiers commonly used in the audio industry. It is an integrated circuit (IC) designed for a wide range of applications in both commercial and residential settings including audio applications, measuring and control systems, and industrial process control. It is designed to provide low-cost and reliable performance with excellent linearity and EMC/ESD protection.

What Is LM2904WHD?

The LM2904WHD is a low-cost, high-performance monolithic amplifier specifically designed for a wide range of applications. It can be used as an individual amplifier with excellent linearity and EMC/ESD protection. The device is available in either the dual in-line package (DIP) or surface mount (SMT). It has a maximum power rating of 4W at 25V, with a maximum supply voltage of 30V. Its features include: high power supply rejection ratio (PSRR), high open-loop gain, low distortion, and low power consumption.

LM2904WHD Application Field

The LM2904WHD is primarily used for audio applications such as for amplifying line inputs, pre-amplifying microphone inputs, or providing a high-gain output. It is suitable for use in audio systems, communication systems, and other high-performance applications. The LM2904WHD is also used for instrumentation amplifier (i.e. in-amp) applications. It can be used as an instrumentation amplifier (i.e. in-amp) with excellent linearity and EMC/ESD protection. It is also used in industrial applications such as process control and measuring devices.

Working Principle of LM2904WHD

The LM2904WHD is designed to provide low-cost and reliable performance with excellent linearity and EMC/ESD protection. The LM2904WHD has two inputs and one output. The first input is a differential input, while the second input is a common-mode input. The output is a voltage-level signal which is proportional to the differential input between the two inputs. The output voltage is proportional to the different input voltage amplitudes with the gain determined by the resistor divider network between the inputs and outputs. The LM2904WHD also has an enable pin, which can be used to enable or disable the amplifier. When the enable pin is set to OFF, the amplifier is disabled and no output voltage is produced. When the enable pin is set to ON, the amplifier is enabled and the output voltage is proportional to the input voltages.

Conclusion

The LM2904WHD is a high-performance functional amplifier used for a wide range of applications. It provides low-cost and reliable performance with excellent linearity and EMC/ESD protection. It is primarily used for audio applications and instrumentation amplifier applications. The working principle of the LM2904WHD is that the output voltage is proportional to the different input voltage amplitudes with the gain determined by the resistor divider network between the inputs and outputs, and an enable pin is used to enable or disable the amplifier.
