Are there 8051 compatible ADC's which sample negative voltages ??? I need an 8 bit ADC with an 8 channel multiplexer which can sample voltages between +5V and -5V...Can you guys suggest any chips for the same?? Why not do some simple signal conditioning on the incoming signals? Seems like a simple gain-of-1/2 opamp and an offset would do the trick. One op-amp per channel. -a |
