APPLICATIONS
CONNECTING THE INPUT
The inputs of the AD736 resemble an op amp, with noninverting
and inverting inputs. The input stages are JFETs accessible at
Pin 1 and Pin 2. Designated as the high impedance input, Pin 2
is connected directly to a JFET gate. Pin 1 is the low impedance
input because of the scaling resistor connected to the gate of the
second JFET. This gate-resistor junction is not externally accessible
and is servo-ed to the voltage level of the gate of the first JFET,
as in a classic feedback circuit. This action results in the typical
8 kΩ input impedance referred to ground or reference level.
This input structure provides four input configurations as
shown in Figure 21, Figure 22, Figure 23, and Figure 24.
Figure 21 and Figure 22 show the high impedance configurations,
and Figure 23 and Figure 24 show the low impedance connections
used to extend the input voltage range.
