Hi friends I hope you all are doing great. In this post, we will have a detailed look at Introduction to TDA7265. It is an integrated circuit that itself has a power rating of twenty-five watts with comprises of a twenty-five-watt audio amplifier. It is a class AB double audio power amplifier that exists in the multi-watts casing.
it is created to use in such applications where high-quality sound is required such as stereo television etc. In this post, we cover its working, applications, and some other related parameters. So let’s get started with Introduction to TDA7265.
Introduction to TDA7265
- The TDA7265 is an audio amplifier integrated circuit. It used in different types of audio amplifiers and power amplification systems.
- It provides short circuit protection for the circuitry where it used and comprises mute enable pinouts.
- it uses very less power almost thirty watts usually it is released in the form of energy during its operation.
- The basic operation is that there is a small level input sound signal is given to it that will get amplified through it.
- The operating voltage of these devices relies on the range of plus-minus five volts to twenty-five volts.
- Total power dissipation is 30W which is the amount of energy released during the working of this device
- There is eleven pinouts of this device that is described here with the details.
- -Vs: At this pinout negative power is provided.
- Output 1: This pinout offered the amplified output of channel A.
- +Vs: Positive power is given through this pinout.
- Output 2: Channel B amplified output pinout given here.
- Mute: To disable the audio output this pin becomes low.
- -Vs: Here negative power is provided.
- In+2: It is the positive or non-inverting pinout of channel B.
- N-2: That is negative or inverting input pinout of channel B.
- Gnd; Here ground is linked.
- In+1: Here inverting input of channel A is linked.
- In+1: That is used to positive terminal of channel A.
- The main features of this module are described here
- It offered different voltage values of operation.
- There is no pop exist during on and off this board.
- It comprises of mute pinouts
- It provides value of ouput power in the range of 25 + 25 W @ RL = 8 Ω, Vs = ± 20V.
- There are very less few elements needed to the operation of this amplifier.
- It provides protection from the short circuit.
- It has the ability to offered overloaded protection.
- It offers the Split supply
- The value of operating voltage for this device lies in the range of from plus-minus five volts to plus-minus twenty five volts.
- The power dissipation for it is thirty watts.
- The extreme value of voltage provided to this has a range of plus-minus twenty-five volts.
- The range of operating temperature for this board is minus twenty centigrade of plus eighty-five centigrade.
Working of TDA7265
- In below diagram, you can see the circuit diagram for this module. To make the amplifier just linked the element of you circuit with this amplifier.
- This circuitry is getting power from 2 power sources first one is the negative and the second one is positive.
- The mute pinout triggered low to the output that is not required.
- In this circuit there are 2 speakers of twenty-five watts are operating through this IC.
- The audio input of channel A is provided to pinout no seven and the output which is amplified will be listed from left side speaker.
- The audio for channel B is provided at the pinout eleven and amplified output will be listed from the right speaker.
How to Choose Best Project Manufacturer
- Friends till now you have got a lot of knowledge about TDA7265. But for practical working and construction of your project in which you are using this device, you will have to project a manufacturer company that can make your project easy and cost reliable.
- Here I am suggesting to you one and only PCBWAY. the main services provided by this manufacturer is PCB, PCBA, and PCB prototyping services under one roof.
- The PCBs provided by these suppliers are single-sided PCB, double-sided PCB, rigid PCB, flex PCB, you get can any type of PCB board according to your requirements with reasonable prices.
- They have a team of highly professional and technical skills professionals that deal with different orders in a single day and provide products to their customers according to the required day.
- You must also use this project manufacturing company it provides each and every product on a very reasonable package. With that it also sponsors different projects for students you must avail of that opportunity.
- Currently, they are providing very interesting offers related to Christmas you must avail that offers till 31 DEC, 2020. There is a contest for projects also happening related to projects you can submit your projects for that contest. Click here to get these Christmas offers. So hurry to get it.
- The basic applications of this device are explained here.
- It used in stereo televisions.
- it sued in guitar amplfieres cirucits.
- In hobby projects it preferred.
- Used to create audio power amplifiers.
- Different types of music players used this device.
- Woofers amplify used it.
That is a detailed post about TDA7265. I tried my level best to explain each and every parameter related to this post. If you have any further query ask in the comments. thanks for reading. Have a nice day.
