• Manufacturer Part Number: clc5633
• Description: Triple, High Output, Programmable Gain Buffer
• Manufacturer: National Semiconductor Corporation

Application Division
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

Dual Supply Operation
The CLC5633 operates on dual supplies as well as signal
supplies. The non-inverting and inverting configurations are
shown in Figure 7 , Figure 8 , and Figure 9 .
Load Termination
The CLC5633 can source and sink near equal amounts of
current. For optimum performance, the load should be tied to
