TL084BCDR

 


The operational amplifier is an essential electronics components distributor. The concept emerged from the development of analog computers in 1940. The name operational amplifier refers to the device's ability to perform various operations such as summation, integration, subtraction, etc. 

 

Throughout WWII, several analog computers were employed to develop "smarter" weapons capable of estimating where a target would have been some time in the future, determining the best firing circumstances to assure that a shell would encounter. The ability to instantly "program" an analog computer by adjusting amplifier gains and connections made it a valuable tool for warfare and academic study. 

 

The historical event helps in highlighting the importance of operational amplifiers. The critical parameters of the amplifier are: 

  • The slew rate
  • Gain
  • Input voltage handling
  • Power consumption
  • Offset voltage
  • Harmonic distortions
  • Noise
  • IC dimensions. 

For an ideal amplifier, the following characteristics should be considered:

  • Higher input resistance
  • Open-loop gain
  • Bandwidth
  • Common-mode rejection ratio (depends upon the input voltage supply and differential gain)
  • Zero output resistance.

The manufacturers continue introducing more products to meet these challenges and optimize the parameters. One of the products is the TL084BCDR FET input amplifier.

 

TL084BCDR is a FET-Input operational amplifier. FET input technique is applied to optimize the parameters. TL084BCDR FET input operational amplifier is a 14 pin Integrated circuit that is SOIC packaged. Amplifier type is J-FET with 4 circuits. The module TL084BCDR has a slew rate of about 13 V/us, higher than the previous generation. The slew rate is the rate at which an operational amplifier can change its output; concerning the change in the input. A higher slew rate is considered best, as it takes less time to respond. Another parameter of the module TL084BCDR is its voltage range from 10 to 30 volts. The output channel current of TL084BCDR is 10 mA, and the input supply current is 1.4 mA for four channels. The power consumption of the module is low at 680 mW. The most important parameter is gain, and TL084BCDR has a gain of 106.02 dB (very high). The input noise current density is 0.01 pA/sqrt Hz. The common-mode rejection ratio of the module TL084BCDR is also high at 86 dB. Input voltage noise density of the module TL084BCDR is 18 nV/sqrt Hz. 

 

The product can be used most simply due to its easy architecture. Pin configuration of the module TL084BCDR is given in the datasheet. There are four amplifiers inside a single package, and it is preferred for many audio amplifiers due to lower harmonic distortion and low noise content. Other applications of the module TL084BCDR are: 

  • N]Battery test types of equipment
  • String and center inverters used in solar energy harvesting
  • Pro audio mixers
  • Single-phase online UPS 
  • AC
  • Servo drive control
  • Three-phase UPS
  • Power stage modules.

TMS320F28034PNT Microcontrollers

Image
A microcontroller is an integrated circuit device denoted by μC or uC. It uses a microprocessor unit (MPU), memory, and peripheral to control other portions of an electronic system. These devices are optimized for applications that require both processing functionality and agile. It is a small, low-cost, and self-contained computer-on-a-chip used as an embedded system. A few microcontrollers may utilize four-bit expressions and work at clock rate frequencies, which usually include an eight or 16-bit microprocessor. Microcontrollers usually must have low-power requirements since many devices they control are battery-operated. The dominant part of microcontrollers being used nowadays is implanted in other apparatus. The 2803x (C28x) family is a member of the TMS320C2000™ microcontroller (MCU) platform. The C28x-based controllers have the same 32-bit fixed-point architecture as existing C28x MCUs. It is a very efficient C/C++ engine, enabling users to develop their system control soft...

Types of Transmission Line

Image
  Transmission line is a cable that transfer Electromagnetic wave from source to destination. Conventional electrical cables are adequate for carrying low frequency alternating current (AC), such as mains electricity, which reverses direction 100 to 120 times per second, and audio transmissions.  however, Electrical cables cannot be utilized to carry radio wave flux over around 30 kHz since the energy starts to radiate off the cable as radio signals, resulting in power dissipation. Radio frequency currents also generally reflect from cable irregularities like connections and joints and flow back across the cable towards to source. Typically transmission lines are distinguished by having uniform cross sectional dimensions over entire length, resulting in a standard impedance, known as the characteristic impedance, to minimize reflections. Parallel lines (ladder lines, twisted pairs), coaxial cable, and planar transmission lines such as stripline and microstrip are exampl...
