Functional Description
The circuit is a differential amplifier with current output and
feedback. The simplified schematic is shown in Figure 1. The
output impedance is set by the value of the feedback resistors
(R3-R6) and the gain of the current mirrors. Amplifier gain is
set by R1 and R2. All of these resistors are internal due to the
high bandwidth of the amplifier.
The common mode output voltage (both outputs together) can
be varied by changing the voltages on +Vb1, +Vb2 and -Vb.
Making all three voltages more negative (for instance, +Vb’s
change from +5 to +3, and -Vb changes from -5 to -7) will
cause the output common mode level to become more positive.
The opposite conditions will cause the output common mode
level to become more negative. This can be very useful in driving
differential circuits which have an elevated DC common
mode input level. See Adjusting Common Mode Output
Offset Voltage section for more details.
By varying +Vb1 and +Vb2 differentially, the differential out-
put offset can be adjusted. See Trimming Differential Output
Offset Voltage for more details.
