GAIN SETTINGS
The gain for each channel is set by its corresponding 8-bit
code, either R[7:0] or L[7:0]; see Figure 2. The gain code
data is straight binary format. If we let
N
equal the decimal
equivalent of R[7:0] or L[7:0], then the following
relationships exist for the gain settings:
For N = 0:
Mute Condition. The input multiplexer is connected to
analog ground (AGNDR or AGNDL).
For N = 1 to 255:
Gain (dB) = 31.5 [0.5
(255 N)]
This results in a gain range of +31.5dB (with N = 255) to
95.5dB (with N = 1).
Changes in gain setting may be made with or without zero
crossing detection. The operation of the zero crossing
detector and timeout circuitry is discussed later in this data
sheet.
