Definition of Terms
Supply Voltage (VSUPPLY). The total supply voltage from
V+ to V-.
Supply Current. The supply current required from the
power supply to operate the device, excluding load currents
and the currents through RA and RB.
Frequency Range. The frequency range at the square wave
output through which circuit operation is guaranteed.
Sweep FM Range. The ratio of maximum frequency to mini-
mum frequency which can be obtained by applying a sweep
voltage to pin 8. For correct operation, the sweep voltage
should be within the range:
(2/3 VSUPPLY + 2V) < VSWEEP < VSUPPLY
FM Linearity. The percentage deviation from the best fit
straight line on the control voltage versus output frequency
curve.
Output Amplitude. The peak-to-peak signal amplitude
appearing at the outputs.
Saturation Voltage. The output voltage at the collector of
Q23 when this transistor is turned on. It is measured for a
sink current of 2mA.
Rise and Fall Times. The time required for the square wave
output to change from 10% to 90%, or 90% to 10%, of its
final value.
Triangle Waveform Linearity. The percentage deviation
from the best fit straight line on the rising and falling triangle
waveform.
Total Harmonic Distortion. The total harmonic distortion at
the sine wave output.
