AMPLIFIER GAIN SETTING<br />
Setting a value in the OptAD.GainM1 member controls the gain <strong>of</strong> the input<br />
amplifier. The following values are possible:<br />
Value Resulting gain<br />
0 internal_signal = 1 * external_signal<br />
1 internal_signal = 1.5 * external_signal<br />
2 internal_signal = 3 * external_signal<br />
3 internal_signal = 6 * external_signal<br />
4<br />
internal_signal = 12 * external_signal<br />
>4 internal_signal = 1 * external_signal<br />
