AC Coupled Single Supply Operation
Figures 4, 5, and 6 show possible non-inverting and invert-
ing configurations for input signals that go below 0.8V DC.
Figure 4: AC Coupled, A
v
= -1V/V Configuration
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 CLC453 operates on dual supplies as well as single
supplies. The non-inverting and inverting configurations
are shown in Figures 7, 8 and 9.
