Hi Geoff You might also look at MAXIM at the MAX127, 128, 1270, 1271, 197, 199, 196 and 198. The spec's are ADC that incorporate a track/hold, a voltage ref, an 8-channel analog multiplexer, software-programmable input range, on on-chip clock, and two power driven down modes. 28 pin SSOP package. I'm sure you can download a spec sheet at http://www.maxim-ic.com Ron Bockelmann -----Original Message----- From: Cumhur Kizilari To: PICLIST@MITVMA.MIT.EDU Date: Wednesday, October 28, 1998 8:43 AM Subject: Re: A/D converter problem >Geoff Wootton wrote: >> >> Hi, >> >> I'm looking into a project that requires the reading of voltages output >> from 10 sensors and inputting the values to my PC through the parallel >> port.
