AC COUPLED SINGLE SUPPLY OPERATION
Figure 4
,
Figure 5
, and
Figure 6
show possible non-inverting
and inverting 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 LMH6718 operates on dual supplies as well as single
supplies. The non-inverting and inverting configurations are
shown in
Figure 7
,
Figure 8
, and
Figure 9
