Application Information
(Continued)
The CLC5509 system dynamic range performance is enhanced by using the CLC5523 variable gain amplifier as a post amplifier.
See Figure 4 below.
The signal gain range is divided between the CLC5509 preamplifier and the post amplifier to allow wider dynamic range and bet-
ter performance for high crest factor signals. There are two common ways the CLC5523 variable gain could be controlled. The
first, Figure 5 uses a DAC to digitally increase the gain in discrete steps. The second Figure 6 uses an AGC loop to maintain the
maximum system input signal-to-noise. Refer to the CLC5523 data sheet applications for the implementation details.
