Application Division (Continued)

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 VCC =

+5V)

Dual Supply Operation

The CLC5632 operates on dual supplies as well as single

supplies. The non-inverting and inverting configurations are

shown in

Figure 7, , and .
