LM131A/LM131, LM231A/LM231, LM331A/LM331  
Precision Voltage-to-Frequency Converters  
General Description  
The LM131/LM231/LM331 family of voltage-to-frequency  
converters are ideally suited for use in simple low-cost cir-  
cuits for analog-to-digital conversion, precision frequency-  
to-voltage conversion, long-term integration, linear frequen-  
cy modulation or 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 ad-  
vantages of the voltage-to-frequency conversion tech-  
niques, and is easy to apply in all standard voltage-to-fre-  
quency converter applications. Further, the LM131A/  
LM231A/LM331A attains a new high level of accuracy ver-  
sus temperature which could only be attained with expen-  
sive voltage-to-frequency modules. Additionally the LM131  
is ideally suited for use in digital systems at low power sup-  
ply voltages and can provide low-cost analog-to-digital con-  
version in microprocessor-controlled systems. And, the fre-  
quency from a battery powered voltage-to-frequency con-  
verter can be easily channeled through a simple photoisola-  
tor to provide isolation against high common mode levels.  
has low bias currents without degrading the quick response  
necessary for 100 kHz voltage-to-frequency conversion.  
And the output is capable of driving 3 TTL loads, or a high  
voltage output up to 40V, yet is short-circuit-proof against
