• Manufacturer Part Number: clc416
• Description: Dual Low-power, 120mhz Op Amp
• Manufacturer: National Semiconductor Corporation

Differential Line Receiver
Figure 5 illustrates a Differential Line Receiver. The
circuit will convert differential signals to single-ended signals.

Bandpass Filter
Figure 6 illustrates a low-sensitivity bandpass filter and
design equations. This topology utilizes the CLC416’s
closely matched amplifiers to obtain low op-amp
sensitivity at high frequencies. The CLC405 is used as
a buffer to obtain low output impedance. The overall
circuit gain is unity. For additional gain, the CLC405
can be configured as a non-inverting amplifier.
To design the filter, choose C and then determine values
for R and R
