Hello, readers welcome to new post. Here we will discuss Introduction to LF353N Op-Amp. The LM353N is designed as an input amplifier for low-noise, low-current and fast switching audio applications commonly used in dual-supply operation. It features a highly stable, programmable output stage, low noise and is based on the latest CMOS technology.
Dual Package Input JFET Operational Amplifier
- The LM353N is less noise creation dual operational amplifier used for high-speed switching circuits. Its gain control ability is large less noise and less distortion operation having linear behavior for audio and visual signal.
Basic Application Circuits
- The LM353N is a dual package input JFET operational amplifier. That is, the input of this op-amp are connected through a high voltage JFET making it suitable for low noise, low current and fast switching audio applications commonly used in dual supply operation.
- The LM353N is not just an op-amp, but a family of linear feedback operational amplifiers. These include the LM353N, the LM353T and the LM353P that represents three different versions of the same op-amp with different characteristics.
- The suffixes T and P stand for Texas Instrument, which is one of the biggest suppliers of audio ICs in Databook with over 140,000 ICs from 6 micron to 50 microns.
Featues of LM353N
- It comes in PDIP packaging
- Its input has a high value of impedance
- Gain bandwidth is four megahertz
- Input volts are ±18 volts
- It has eight pinouts
Optimizing Performance in Audio Applications
- The primary goal of the LME5321 is to deliver high-quality audio performance across a wide range of input and output requirements, including guitar amps, electronic instruments and sound reinforcement equipment, as well as digital audio.
- The LM5321 has been optimized for low-noise operation, high gain and fast switching.
- The LM5321 is a dual op-amp designed to deliver linearity equal to or better than that of the state-of-art power amplifiers in its class (such as the LM4562).
- The LM5321 features the latest technology and is available in two package sizes: 1/0 – 5 V (MOSFET) and 1/2 – 3 A (PQFN).
Conclusion
The LM353N is a Dual Package Input JFET Operational Amplifier. That is the input of these operational amplifier linked through a high-voltage JFET making it prefferd for low-noise, low-current and high speed switching audio applications commonly used in Dual supply operation. It can be used as an output stage in home theater systems and audio amplifiers.
It’s inherent characteristics make it a good match for the LM353P, which reduces distortion by up to 40%, consumes less power, has faster startup times, and offers better rail stability for audio applications.
While the LM353N provides all of these characteristics, you also get two less-expensive alternative op-amp models that offer slightly lower distortion performance than the LM353N
