Hi team,

Customer wants a MULTIPLIER, one input is 12V and another is 1V. Could you please recommend the best fit?

Hi Nison,

MPY634 is a legacy multiplier, and we do not have new product to replace the part.

Could you provide me with the design requirements and implemented application? What frequency are we talking about and cost consideration. Perhaps we can find you an alternative solution.

Best,

Raymond

Hi Raymond,

Customer will not convert the voltage to frequency. They just want to convert two input voltage to one multiplied voltage.

Hi Nison,

So it is multiplier function - what is the operating frequency? MPY634 may be the only one.

Here is a simulated example.
