Our advantages
Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service.

Description
The voltage-to-frequency converter provides an output pulse sequence that is accurately proportional to the applied input voltage.
The LM331 can convert output frequencies from 1Hz to 100KHz when powered as low as 4V. It is well-suited for use in simple, low-cost circuits for applications such as analog-to-digital conversion, long-term integration, linear frequency modulation or demodulation, frequency-to-voltage conversion, and many other functions.
