Precision Voltage-to-Frequency Converter
In this application (Figure 3) the XR-4151 is used with an
operational amplifier integrator to provide typical linearity
of 0.05% over the range of 0 to -10V. Offset is adjustable
to zero. Unlike many VFC designs which lose linearity
below 10mV, this circuit retains linearity over the full range
of input voltage, all the way to 0V.
Trim the full scale adjust pot at V
I
= -10V for an output
frequency of 10kHz. The offset adjust pot should be set for
10Hz with an input voltage of -10mV.
The operational amplifier integrator improves linearity of
this circuit over that of Figure 2 by holding the output of
the source, Pin 1, at a constant 0V. Therefore, the linearity
error due to the current source output conductance is
eliminated. The diode connected around the operational
amplifier prevents the voltage at pin 7 of the XR-4151
from going below 0. Use a low-leakage diode here, since
any leakage will degrade the accuracy. This circuit can be
operated from a single positive supply if an XR-3403
ground-sensing operational amplifier is used for the
integrator. In this case, the diode can be left out. Note that
even though the circuit itself will operate from a single
supply, the input voltage is necessarily negative. For
operations above 10kHz, bypass pin 6 of the XR-4151
