The LM331AN is a precision Voltage-to-frequency Converter, ideally suited for use in simple low-cost circuits for analogue-to-digital conversion, precision frequency-to-voltage conversion, long-term integration, linear frequency 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 advantages of the voltage-to-frequency conversion techniques and is easy to apply in all standard voltage-to-frequency converter applications. Further, the LMx31A attain a new high level of accuracy versus temperature which could only be attained with expensive voltage-to-frequency modules. Additionally the converter is ideally suited for use in digital systems at low power supply voltages and can provide analogue-to-digital conversion in microprocessor-controlled systems.

• Improved performance in existing voltage-to-frequency conversion applications
• Split or single-supply operation
• Pulse output compatible with all logic forms
• ±50ppm/°C Maximum excellent temperature stability
• 15mW typical at 5V Low power consumption
