Test and measurement G=5 GAIN (dB) 15 GENERAL DESCRIPTION The AD8250 user interface consists of a parallel port that allows
users to set the gain in one of two ways (see Figure 1). A 2-bit word
sent via a bus can be latched using the WR input. An alternative is
to use the transparent gain mode where the state of the logic levels
at the gain port determines the gain. 10
