FEATURES  
DESCRIPTION  
The LM231/LM331 family of voltage-to-frequency  
converters are ideally suited for use in simple low-  
cost circuits for analog-to-digital conversion, precision

demodulation, and many other functions. The output  
when used as a voltage-to-frequency converter is a  
pulse train at a frequency precisely proportional to the  
applied input voltage. Thus, it provides all the  
inherent advantages of the voltage-to-frequency  
conversion techniques, and is easy to apply in all  
standard voltage-to-frequency converter applications.  
Further, the LM231A/LM331A attain a new high level  
of accuracy versus temperature which could only be

modules. Additionally the LM231/331 are ideally  
suited for use in digital systems at low power supply  
voltages and can provide low-cost analog-to-digital  
conversion in microprocessor-controlled systems.  
And, the frequency from a battery powered voltage-  
to-frequency converter can be easily channeled  
through a simple photo isolator to provide isolation  
against high common mode levels.  
Low Cost  
The LM231/LM331 utilize  
a
new temperature-  
compensated band-gap reference circuit, to provide  
excellent accuracy over the full operating temperature  
range, at power supplies as low as 4.0V. The  
precision timer circuit has low bias currents without  
degrading the quick response necessary for 100 kHz  
voltage-to-frequency conversion. And the output are  
capable of driving 3 TTL loads, or a high voltage  
output up to 40V, yet is short-circuit-proof against  
VCC
