9 / 17 page  PGA2311 SBOS218A – DECEMBER 2001 – REVISED JUNE 2002 www.ti.com 9 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 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. Figure 3.
