TYPICAL APPLICATIONS
Single Supply Voltage-to-Frequency Converter
Figure 2shows the simplest type of VFC that can be
made with the XR-4151. The input voltage range is from 0
to +10V, and the output frequency is from 0 to 10kHz. The
full scale frequency can be tuned by adjusting R
S
, the
output current set resistor. This circuit has the advantage
of being simple and low in cost, but it suffers from
inaccuracy due to a number of error sources. Linearity
error is typically 1%. A frequency offset will also be
introduced by the input comparator offset voltage. Also,
response time for this circuit is limited by the passive
integration network R
B
C
B
. For the component values
shown in Figure 2,response time for a step change input
from 0 to +10V will be 135msec. For applications which
require fast response time and high accuracy, use the
circuit of Figure 3
