Output Amplitude:
Maximum output amplitude is inversely proportional to
the external resistor, R
3
, connected to Pin 3 (see
Figure 3). For sine wave output, amplitude is
approximately 60mV peak per k of R
3
; for triangle, the
peak amplitude is approximately 160mV peak per k of
R
3
. Thus, for example, R
3
= 50k would produce
approximately 13V sinusoidal output amplitude.
Amplitude Modulation:
Output amplitude can be modulated by applying a dc bias
and a modulating signal to Pin 1. The internal impedance
at Pin 1 is approximately 100k . Output amplitude varies
linearly with the applied voltage at Pin 1, for values of dc
bias at this pin, within 14 volts of V
CC
/2 as shown in
Figure 6. As this bias level approaches V
CC
/2, the phase
of the output signal is reversed, and the amplitude goes
through zero. This property is suitable for phase-shift
keying and suppressed-carrier AM generation. Total
dynamic range of amplitude modulation is approximately
55dB.
CAUTION:
AM control must be used in conjunction with a
well-regulated supply, since the output amplitude now becomes
a function of V
CC
.
