Vamsi suggests using Analog Devices' AD633 as the multiplier in our project. The circuit consists of a standard implementation mentioned in the datasheet. (Fig. 3).
Specifications
| Transfer Function | [(X1–X2)(Y1–Y2)/10] + Z | |
| Slew Rate (V/µs | 20V/µs | |
| Supply Voltage (V max) | ±18V | |
| Supply Current (max) | 6mA | |
| Temp Range | -40 to 85°C | |
| Package | DIP/SOIC |
From Analog Devices website. The datasheet.
AD633 seems cheap, and very popular. Good for it. Also, AD seem very forthcoming to give free samples. I will try something about that.

check AD 539
I somehow can't seem to download the datasheet. The main problem with using such an IC would be the fact that a lot of noise would exist in the output for high frequencies. The same problem came with the earlier IC Vamsi used. So find out the noise(which would probably in dimensions of mV) and if possible put an update about it for others to see. I have doubts whether it'd work well.
