Load Impedance Conversion
Set up the CLC5623 as a difference amplifier:
Make the best use of the CLC5623’s output drive
capability as follows:
where R
eq
is the transformed value of the load imped-
ance, V
max
is the Output Voltage Range, and I
max
is the
maximum Output Current.
Match the line’s characteristic impedance:
Select the transformer so that it loads the line with a
value very near Z
o
over frequency range. The output
impedance of the CLC5623 also affects the match. With
an ideal transformer we obtain:
where Z
o(5623)
(j
ω
) is the output impedance of the
CLC5623 and |Z
o(5623)
(j
ω
)| << R
m
.
The load voltage and current will fall in the ranges:
The CLC5623’s high output drive current and low
distortion make it a good choice for this application.
Bandpass Filter
Figure 18 illustrates a low-sensitivity bandpass filter and
design equations. This topology utilizes the CLC5623’s
closely matched amplifiers to obtain low op-amp
sensitivity at high frequencies.
used as a buffer to obtain low output impedance. The
overall circuit gain is unity. For additional gain, the third
CLC5623 can be configured as a non-inverting amplifier.
The third CLC5623 is
To design the filter, choose C and then determine values for
R and R

based on the desired resonant frequency (f

)
and Q factor.

Instrumentation Amplifier
An instrumentation circuit is shown on the front page and
reproduced in Figure 19. The DC CMRR can be fine
tuned by adjusting R
