Output Amplifier Gain Control
Table 5. DC Gain of Output Amplifier for Different Gain Settings
The output amplifier gain is controlled by a 4-bit word. In
principle, the output amplifier can be configured in unity feedback
mode by a permanent high signal on UNITYGAIN, but the
purpose of this mode is purely diagnostic. The "normal" gain
settings vary on an exponential scale.

In first approximation, the gain setting is independent of
bandwidth, as the amplifier is a 2-stage design. The first stage
sets the gain, and the second stage is a unity gain buffer, that
determines bandwidth and slew rate. There is however some
influence of gain setting on bandwidth.
