audio vox

good day sir
can you please helf me to get an ic that im going to use in autovox for mini audio sensing

Good day sed,
Can you be more descriptive of the problem?

1. Do you want to know the part number of a "part number rubbed off" chip?
2. Do you want to design a circuit to sense audio?

Regards,
Manu

i want to build audiovox using this ic but i dont know what ic i can use it? if detect small noisy or low voice triger the pin 6 is out put.

pin 1 sensitive input audio
pin 4 Ground
pin 6 out put voltage when detect signal
pin 8 is vcc 5volt

sir what ic i can use?

Why not design your own vox switching circuit? There isn't a dedicated "vox chip" - I have used just a couple of transistors for this purpose. You have to be aware that a crude sound operated switch will respond to ANY sound that's loud enough for the circuit to detect.

A proper Vox circuit uses stages of audio filtering and noise cancellation techniques to prevent false triggering. The last Vox that I designed for a radio communications manufacturer used three quad op-amps, two FETs, a comparator IC and a bipolar transistor. The circuit is patented, so I can't post it here (it would be too complicated for you to copy, anyway!).

Look at simple "sound operated switch" circuits.
