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

with

expensive

voltage-to-frequency

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

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

V_CC
