0 to 10V range to 0 to 4.096V range

[AK]

Hi,

Does anyone know of a single chip solution to convert a 0 to 10 V signal to a 0 to 4.096V signal (or 0 to 5V)? I know I could use a voltage divider, but this didn't seem like a very high precision method. Thanks for the help.

Vishay, do some nice laser trimmer resistive dividers, in a three pin package, which can be combined wth any precision op-amp, and probably represents the cheapest really accurate solution. Analog devices do multipliers and dividers, which can be used to generate this sort of ratio, but get expensive, as well as programmable gain ampifiers. Assuming that the source impedance, will not mind some resistive load, I'd suspect a simple resistive divider, followed by a single supply op-amp, would probably be the most practical/economical solution (remember that if you don't want to have to fiddle with extra supplies,the op-amp will need an input range, and an output range, that includes 0v).
