Looking for a 5V analog multiplier

[hyleeinhit]

Hi,

I am looking for an analog multiplier chip which operate under 5V. Both of two inputs are analog sine signals with amplitude less that 1V. I searched several chips, but all of these operated from +/-4V ~+/-15V, including AD632/3, AD834, RC4200, MC1494, MLT04, mpy5/634, and MT09. Any suggestion? Thanks.

are you not interested in using discrete multiplier circuit by using 4 OPAMPs you can use OPAMP such as LM324,TLO82

If no single multiplier chip is available, I am OK with multiplier built with opamp. Can you give me some examples of OPAMP based multiplier? Thanks.

I don't think it can be done with opamps. Depending on the application you may be able to use an MC1496. Otherwise it may be easiest to just boost the supply voltage with a 555-based charge pump or something.

Perhaps you could use the AD8343 (s. PDF below), which is a DC-to-2.5 GHz Active Mixer operating from a single 5V power supply.
I guess it is based on the AD834, and probably could also be used with 2 sine input signals.

Hi;
What about this one;

Required linearity? Frequency range?

4053 is an analog multiplexer. It can be used as a sign multiplier, multiplying a square wave carrier frequency with an analog signal. If the application allows to filter harmonics in the output spectrum, it can work as a high linearity analog multiplier replacement.

The linearity should be good. The target freq is 1Hz.

Op amps can't do multiplication without a non-linear added circuit. You can add and subtract signals but not multiply them.

good point.
