OUTPUT AMPLITUDE ADJUSTMENT
The high and low output levels of the CLC005 are set by a
circuit shown simplified in Figure 8 Output high and low lev-
els may be set independently with external resistor networks
connected between R
(pin 3), R
(pin 4) and the
power supplies. The resistor networks affect the high and
low output levels by changing the internally generated bias
voltages, V
and V
. The nominal high and low output levels
are V
CC
1.7V and V
3.7V, respectively, when the pins
R
and R
are left unconnected. Though the internal
components which determine output voltage levels have ac-
curate ratios, their absolute values may be controlled only
within about
±
15% of nominal. Even so, without external ad-
justment, output voltages are well controlled. A final design
should accommodate the variation in externally set output
voltages due to the CLC005’s part-to-part and external com-
ponent tolerances.
Output voltage swing may be reduced with the circuit shown
in Figure 9 A single resistance chosen with the aid of the
graph, Figure 10 is connected between pins 3 and 4. Output
voltage swing may be increased with the circuit of Figure 11
Figure 12is used to estimate a value for resistor R. Note that
both of these circuits and the accompanying graphs assume
that the CLC005 is loaded with the standard 150
. Be aware
that output loading will affect the output swing and the high
and low levels. It may be necessary to empirically select re-
sistances used to set output levels when the D.C. loading on
the CLC005 differs appreciably from 150
.
