Figure 16. Slew RAM—Linear Update Decreasing Ramp
Constant dB and RC Type (Exponential) Update Math
Exponential math is accomplished by shifts and adds with a
range from 6.1 ms to 1.27 s (–60 dB relative to 0 dB full scale).
When the ramp type is set to 01 (constant dB), each step size is
set to the current value in the slew data. When the ramp type
bits are set to 10 (RC type), the step sizes are equal to the
difference between the values in the target RAM and slew RAM.
Figure 17 and Figure 18 show examples of this type of
target/slew RAM ramping. A decreasing ramp of both the
constant dB and RC type ramps is a mirror image of the
constant dB increasing ramp, and is show in Figure 19.
