About AD73322 - D. V. Saradhi - Mar 5 0:02:00 2002





Hai all,

In AD73322 manuals, it is given that the control register D was used to control
the i/p and o/p gains.

If any one knows, what is the variable gain that we get by changing the bits in
this control register?
Regards,

Saradhi.

Are these DSPs that ADI makes? Never heard of these...

Hello,

These are not DSP's, but a telecom codec.
http://www.analog.com/productSelection/pdf/AD73322_b.pdf

page 14, table IV, gives you the table for the input gain.
page 16, table V, gives you the table for the output gain

Regards,
Eirik
