Application Hints
Recommended Layout Precautions: RF/video printed cir- , ' MN
cuit board layout rules should be followed when using the
LH4033C and LH4063C since they will provide power gain INPUT CD
to frequencies over 100 MHz. Ground planes are recom- OFFSET
mended and power supplies should be decoupled at each FRESH T. ° OUTPUT
device with low inductance capacitors. (OPEN)
Offset Voltage Adjustment: Both the LH4033C's and OFFSET
LH4063C's offset voltages have been actively trimmed by ADJUST
laser to meet guaranteed specifications when the offset pre- 2000
set pin is shorted to the offset adjust pin. This pre-calibre i':
tion allows the devices to be used in most DC or AC epplica- . T. - CN
tions without individually offset nuiling each device. If offset TL/K/10008-5
null is desirable, it is simply obtained by leaving the offset
preset pin open and connecting a trim pot of 200ft for the
LH40330 or 1 kn tor the LH4063C between the offset ad-
just pln and v- as illustrated in Figures 1 and 2.

FIGURE 2. Offset Zero Adjust for LH4063C
Application Hints (Continued)
Operation from Single or Asymmetrical Power Supplies;
Both device types may be readily used in applications where
symmetrical supplies are unavailable or not desirable. A typ-
ical application might be an interface to a MOS shift register
where v+ = + 5V and v- = -12V. In this case, an appar-
ent output offset occurs due to the device's voltage gain of
less than unity. This additional output offset error may be
predicted by:
(V+ --W-)
2 = 0.005 (V+ - V-)
Mo 2 (1 - Av)
where:
Av = No load voltage gain, typically 0.99
V+ = Positive supply voltage
v- = Negative suply voltage
For the above example, Avo would be -35 mV. This may
be adjusted to zero by offset voltage adjustment described
earlier. For AC coupled applications, no additional offset oc-
curs if the DC input is properly biased as illustrated in the
“typical applications" section.
Short Circuit Protection: In order to optimize transient re-
sponse and output swing, output current limit has been
omitted from the LH4033 and LH4063. Short circuit Protec-
tion may be added by inserting appropriate value resistors
between V+ and Vc+ pins and v- and Vc‘ pins as illus-
trated in Figures 3 and 4. Resistor values may be predicted

FIGURE 3. LH4033C Using Heslstor Current Llmltlng
The inclusion of limiting resistors in the collectors of the
output transistors reduces output voltage swing. Decoupling
Vc+ and Vc- pins with capacitors to ground will retain full
output swing for transient pulses. Alternate active current
limit techniques that retain full DC output swing are shown in
Figures tr, 6 and 7. In Figures 5 and 6, the current sources
are saturated during normal operation thus apply full supply
voltage to the VC pins. Under fault conditions, the voltage
decreases as required by the overload. For Figure tr:

Using Current Source:
Capacitance Loading: Both the LH4033C and LH4063C
are designed to drive capacitive loads such as coaxial ca-
bles in excess of several thousand picotarads without sus-
ceptibility to oscillation. However. peak current resulting
from (CdV/dt) should be limited below absolute maximum
peak current ratings for the devices.
Thus for the LH4033C:
(-h-1s/i-N-) x CL 3 tom s 1250 mA
and for the LH4063C:
6%) X CL S IQUT S i500 mA
In addition, power dissipation resulting from driving capaci-
tive loads plus standby power should be kept below total
package power rating:

Operation Within an Op Amp Loop: Both devices may be
used as a current booster or isolation buffer within a closed
loop with op amps such as LH0032, LH0062, or LMI 18. An
isolation resistor of 47ft should be used between the op
amp output and the input of LH4033C. The wide bandwidths
and high slew rates of the LH4033C and LH40630 assure
that the loop has the characteristics of the op amp and that
additional rolloff is not required.
Hardware: In order to utilize the full drive capabilities of
both devices, each should be mounted with a heat sink par-
ticularly for extended temperature operation.
DESIGN PRECAUTION
Power supply bypassing is necessary to prevent oscillation
with both the LH40330 and LH40630 in all circuits. Low
inductance ceramic disc capacitors with the shortest practi-
cal lead lengths must be connected from each supply lead
(within
plane. Capacitors should be one or two 0.1 pF in parallel for
the LH40330; adding a 4.7 HF solid tantalum capacitor will
help in troublesome instances. For the LH40630, two
0.1 p.F ceramic and one 4.7 yi' solid tantalum capacitors in
parallel will be necessary on each supply lead.
