Hi Steve
I need 8052 member with 8 channels 12 bit ADC(is there such thing?) to display input voltage to the differential output amplifier with a gain of 1 on 4x20 LCD display.
So this project is 8052 related.
I have both keil and my Raisonance compiler prize that I received yesterday which makes the task easier.
I also done the LCD part before so I might not need any help on 8052 part because its easy.
Yes I just found out that you could do it with 2 op amps, so if I use quad op amps with lots of passive components I can make 2 circuits but it would be nice if I can find a dedicated IC that would do the job to save time.
Line drivers are no good because the ones I found give digital output and I need a linear output to vary the DC input voltage from 0 to 1VDC and make gain 1. So i only use DC voltage out of a pot.
I don't know about the o/p current but i need it to drive NI data aquesition card's differential analog inputs (will look into required current but I guess it won't be much) and LABVIEW with a cable 1 to 2 meters.
