AD633 for multiplier

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.

The development board for PIC18F2455

The previous post contains the link to the datasheet of the PIC18F2455. That thing is huge, some 428 pages. Instead, here is the link to the development board of the same controller. With the development board, I hope, it will be easier to handle USB protocols. (Without it, it seems simply impossible). I havn't been able to fix myself on either of the modules till now. The options are:
1)the dlpdesign module that mandar discussed
2)this PIC module
3)Since I am comfortable with the 8051 architecture, I would like to use a 8051 based controller, am trying to find a suitable one. Any help will be appreciated :-)

Using a USB PIC

The USB microcontroller I have in mind is the PIC 18F2455.

Here is the link for the datasheet. ww1.microchip.com/downloads/en/DeviceDoc/39632b.pdf

This microcontroller not only offers upto 8MHz internal clock, but also has features like setting a self sampling rate through software, an inbuilt ADC (not sure if we can use it though). It provides for having 2 different rates for running the controller and for USB data transfer!
