Minimizing Parasitic Effects on

Small Signal Bandwidth

Long traces between CLC5523 and 0.1mF

bypass capacitors

■

The best way to minimize parasitic effects is to use the

small outline package and surface mount components.

For designs utilizing through-hole components,

specifically axial resistors, resistor self-capacitance

should be considered. Example: the average magnitude

of parasitic capacitance of RN55D 1% metal film

resistors is about 0.15pF with variations of as much as

0.1pF between lots. Given the CLC5523’s extended

bandwidth, these small parasitic reactance variations can

cause measurable frequency response variations in the

highest octave. We therefore recommend the use

of surface mount resistors to minimize these parasitic

reactance effects. If an axial component is preferred, we

recommend PRP8351 resistors which are available from

Precision Resistive Products, Inc., Highway 61 South,

Mediapolis, Iowa.

Keep these traces less than 0.2 inches (5mm)

■

For the devices in the PDIP package, an

additional 1000pF monolithic capacitor should be

placed less than 0.1” (3mm) from the pin

Extra capacitance between the R pin and

ground (C )

■

See the Printed Circuit Board Layout sub-section

below for suggestions on reducing C

■

Increase R if peaking is still observed after

reducing C

Non-inverting input pin connected directly to

ground

■

Place a 50 to 200W resistor between the non-

inverting pin and ground

Adjusting Offsets and DC Level Shifting

Offsets can be broken into two parts: an input-referred term

and an output-referred term. These errors can be trimmed

Small Signal Response at Low A

vmax

When the maximum gain, as set by R and R , is greater

using the circuit in Figure 4. First set V to 0V and adjust

than or equal to A

= 10, little or no peaking should be

the trim pot R4 to null the offset voltage at the output. This

vmax

observed in the amplifier response. When the gain range

is set to less than A = 10, some peaking may

will eliminate the output stage offsets. Next set V to 2V

and adjust the trim pot R1 to null the offset voltage at the

output. This will eliminate the input stage offsets.

vmax

be observed at higher frequencies. At gain ranges of

2 ² A ² 10 peaking can be minimized by increasing

vmax

R . At gain ranges of A

approximately 6dB in the upper octave.

If peaking is observed with the recommended R resistor,

and a small increase in the R resistor does not solve the

problem, then investigate the possible causes and

remedies listed below.
