Figure 3. Serial Interface Timing Requirements.
GAIN SETTINGS
The gain for each channel is set by its corresponding
8-bit code, [7:0] (see Figure 2). The gain code data is
straight binary format. If we let N equal the decimal
equivalent of [7:0], then the following relationships ex-
ist for the gain settings:
For N = 0:
Mute Condition. The input multiplexer is connected to
analog ground.
For N = 1 to 255:
Gain (dB) = 31.5
–
[0.5 w (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 lat-
er in this data sheet.
