Input Bias, Impedance, and Termination
The VIN+ and VIN– inputs have a dc bias level of approxi-
mately 1.47 V below VCC/2, therefore the input signal should
be ac-coupled using 0.1
µF capacitors as seen in the typical
application circuit (see Figure 5).
The differential input impedance of the AD8326 is approxi-
mately 1600
Ω, while the single-ended input is 800 Ω.
Single-Ended Inverting Input
When operating the AD8326 in a single-ended input mode VIN+
and VIN– should be terminated as illustrated in Figure 6. On the
AD8326 evaluation boards, this termination method requires the
removal of R12, R13, R14, R16, R17, and R18. Install a 0
jumper at R15, an 82.5
Ω resistor at R10 for a 75 Ω system, and a
39.2
Ω resistor at R11 to balance the inputs of the AD8326
evaluation board (Figure 11). Other input impedance configura-
tions may be calculated using the equations in Figure 6.

Figure 6. Single-Ended Input Impedance
The inverting and noninverting inputs of the AD8326 must be
balanced for all input configurations.
Differential Input from Single-Ended Source
The default configuration of the evaluation board implements a
differential signal drive from a single-ended signal source. A
Toko 1:1 transformer is included on the board for this purpose
(T3). Enabling the evaluation board for single to differential
input conversion requires R15–R17 to be removed, and 0
jumpers must be installed on the placeholders for R13, R14, and
R18. For a 75
Ω input impedance, R12 should be 78.7 Ω. Refer
to Figure 11 for evaluation board schematic. In this configuration,
the input signal must be applied to VIN–. Other input imped-
ances may be calculated using the equation in Figure 7.

Differential Signal Source
The AD8326 evaluation board is also capable of accepting a
differential input signal. This requires the installation of a 165
resistor in R12, the removal of R13–R14, R17–R18, and the
installation of 0
Ω jumpers for R15–R16. This configuration
results in a differential input impedance of 150
Ω. Other differ-
ential input impedance configurations may be calculated with
the equation in Figure 8.
