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, Av = -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 VCC ÷2

= 2.5V (For VCC = +5V).

Figure 6: AC Coupled, Av = +2V/V Configuration

Dual Supply Operation

The CLC451 operates on dual supplies as well as single

supplies. The non-inverting and inverting configurations

are shown in Figures 7, 8 and 9.

Note: Rb provides DC bias for the non-inverting input.

Rb, RL and Rt are tied to Vcm for minimum power

consumption and maximum output swing.
