Which amplifier is suitable for amplifying the sound ranges from 20Hz to 2Mhz which can be accessed as audio signal

    Hello Sanjay! All of our audio amplifiers are designed to operate within the 20 to 20 KHz listening range with an audio signal input, both analog and digital. Is this what you meant and not up to 2 MHz? For switching frequencies, we do have amplifiers that switch up to 2.1 MHz. What are you specifically trying to do, and what power level are you targeting? You can find all of our analog input and digital input amps at: www.ti.com/.../overview.html Thanks, Jeff

    Hi Jeff ! What do you suggest in the case where I can use the frequency synthesiser to produce frequency of desired level which ranges from 2 Hz to 2MHz and it get amplified to produce noise.Thanks, Sanjay

    Hello Sanjay! What type of input signal is it... Differential Analog Input, Digital Audio Interface (I2S or TDM) input, etc? Also, what is the load that you are trying to drive and at what power level? Thanks, Jeff

    In my project, I'm using the Frequency generator to generate a frequency which is variable (20Hz - 20KHz) (I will be setting the frequency based on the application).Then the generated frequency gets amplified to some extent and the amplified signal is delivered as output through the audio system.
    our Project name is "Frequency-based Protection system" in which the Frequency based signals are used to drive away the animals.
    For instance, an elephant which has the hearable frequency ranges from 12,000 to 16,000 Hz and I will be generating this kind of frequency signals and then it is amplified and produced as output.
    can you suggest me appropriate TI Products for Frequency generator, amplifier, and audio system?
    Thank you for your Reply!...
    I am waiting for your Reply, Jeff.

    Hello Sanjay! 20hz to 20Khz is no problem as I mentioned for our Class D amps... 20Mhz is something we cannot support. For ultrasonic levels you may want to look at some parts of another business within TI: e2e.ti.com/.../ or www.ti.com/.../motor-haptic-driver-products.page Thanks, Jeff
