General Description

The LM131/LM231/LM331 family of voltage-to-frequencyconverters are ideally suited for use in simple low-cost circuitsfor analog-to-digital conversion, precision frequencyto-voltage conversion,long-term integration, linear frequencymodulation or demodulation, and many other functions.The output when used as a voltage-to-frequency converteris a pulse train at a frequency precisely proportional to theapplied input voltage. Thus, it provides all the inherent advantagesof the voltage-to-frequency conversion techniques,and is easy to apply in all standard voltage-to-frequencyconverter applications. Further, the LM131A/LM231A/LM331A attains a new high level of accuracy versustemperature which could only be attained with expensivevoltage-to-frequency modules. Additionally the LM131is ideally suited for use in digital systems at low power supplyvoltages and can provide low-cost analog-to-digital conversionin microprocessor-controlled systems. And, the frequencyfrom a battery powered voltage-to-frequency convertercan be easily channeled through a simple photoisolatorto provide isolation against high common mode levels.The LM131/LM231/LM331 utilizes a new temperaturecompensatedband-gap reference circuit, to provide excellentaccuracy over the full operating temperature range, atpower supplies as low as 4.0V. The precision timer circuithas low bias currents without degrading the quick responsenecessary for 100 kHz voltage-to-frequency conversion.And the output is capable of driving 3 TTL loads, or a highvoltage output up to 40V, yet is short-circuit-proof againstVCC.
