Input Configuration
The MT88E43 provides an input arrangement comprised of an operational amplifier and a bias source (V
is used to bias the opamp inputs at V
the gain. In a single-ended configuration, the opamp is connected as shown in Figure 6. For a differential input
configuration, Figure 7 shows the necessary connections.
