National Semiconductor LM331N Voltage to Frequency Converter

National Semiconductor
Order Code:

82-5028

Brand: National Semiconductor MPN: LM331N

Discontinued


The LM331N voltage-to-frequency converter is ideally suited for use in simple low-cost circuits for A-to-D conversion, precision frequency-to-voltage conversion, long term integration, linear frequency modulation/demodulation etc. When used as a voltage-to-frequency converter, the output is a pulse train at a frequency precisely proportional to the applied input voltage.


  • Temperature compensated band-gap reference circuit
  • Excellent accuracy over the operating temperature range
  • Output is capable of driving three TTL loads
  • Supplied in DIL-8 package
Number of Channels 1
Operating Temperature Range 0 to 70°C
Package/Case DIL-8
Power Dissipation 1.25W
Supply Voltage 4 to 40V
