DC Coupled Single Supply Operation
Figures 1 and 2 show the recommended non-inverting
and inverting configurations for input signals that remain
above 0.8V DC.
Figure 1: Non-Inverting Configuration
Figure 2: Inverting Configuration
AC Coupled Single Supply Operation
Figures 3 and 4 show possible non-inverting and invert-
ing configurations for input signals that go below 0.8V
DC. The input is AC coupled to prevent the need for
level shifting the input signal at the source. The resistive
voltage divider biases the non-inverting input to V
CC
÷ 2
= 2.5V (For V
CC
= +5V).

Dual Supply Operation
The CLC5622 operates on dual supplies as well as
single supplies. The non-inverting and inverting configu-
rations are shown in Figures 5 and 6.
