APPLICATIONS INFORMATION

Capacitive loading on the output reduces the stability of

the op amp. If the capacitive loading is sufficiently high,

the stability margin is decreased to the point of oscillation

at the output. Capacitive loading should be kept below

30pF. Good, tight layout techniques should be maintained

at all times. These parts should not drive long traces and

must never drive a long coaxial cable. When probing the

LTC1563-X,always usea10xprobe.Neverusea1xprobe.

A standard 10x probe has a capacitance of 10pF to 15pF

while a 1x probe’s capacitance can be as high as 150pF.

The use of a 1x probe will probably cause oscillation.

Capacitance to an AC ground is the most likely problem.

Capacitance on the LPA or LPB pins does not affect the

transfer function but does affect the stability of the op

amps. Capacitance on the INVA and INVB pins will affect

the transfer function somewhat and will also affect the

stability of the op amps. Capacitance on the SA and SB

pins alters the transfer function of the filter. These pins are

the most sensitive to stray capacitance. Stray capacitance

on these pins results in peaking of the frequency response

near the cutoff frequency. Poor layout can give 0.5dB to

1dB of excess peaking.

For larger capacitive loads, a series isolation resistor can

be used between the part and the capacitive load. If the

load is too great, a buffer must be used.

To minimize the effects of parasitic layout capacitance, all

of the resistors for section A should be placed as close as

possible to the SA pin. Place the R31 resistor first so that

it is as close as possible to the SA pin on one end and as

close as possible to the INVA pin on the other end. Use the

same strategy for the layout of section B, keeping all of the

resistors as close as possible to the SB node and first

placing R32 between the SB and INVB pins. It is also best

if the signal routing and resistors are on the same layer as

the part without any vias in the signal path.

Layout Precautions

The LTC1563-X is an active RC filter. The response of the

filter is determined by the on-chip capacitors and the

external resistors. Any external, stray capacitance in par-

allel with an on-chip capacitor, or to an AC ground, can

alter the transfer function.
