Gain Control Pins

The gain setting for each channel is given in Table 2.

Gi(1:0)

Description

0 0

Channel OFF (default value set by pull-down devices)

0 1

Channel ON, G = 6 dB

1 0

Channel ON, G = 12 dB

1 1

Table 2. Channel gain setting.

Note: For applications that require less than 3 outputs, the unused differential outputs and the corresponding channel

gain setting pins can be left floating. The default channel gain setting is “channel OFF [0:0]” (set by internal pull down

resistors).
