There is now 12 or 16 bits reliable and cheap ( up to 8 channels ) like
ADC12030 $5.30 http://www.national.com/pf/AD/ADC12030.html
(Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold SOIC WIDE No 12 bits 8.80 )
Besides the already made circuit by Sajith ( Thanks Lord ! ) , that idea can bring some advantages for our system with high speed ( 8 microsecs ) andlow prices ($5,30) ( without cause interference ( until) in the medical RS232EEG certification ) .
By the way - what's the cost of the actual INPUT section only ( without the processor ) of RS232EEG ?
