Post by thread:MAXIM's Serial ADC's multichannel 10 and 12 bit

Hi all, I'm about to select a few MAXIM ADC's in a muxed RMS converter design with the correct Analog Devices chip etc. Some of the items on maxim's web page are generally unavailable http://www.maxim-ic.com and I'm wondering which are the most readily available or usable. Anyone have experience with the MAX1202,1203,1204, 147, 148, 181, 148, 192 ?? Or anyone suggest/recommend another 8 channel 10/12 bit ADC with serial interface ?

Recently I had to choose a 12 bit serial A/D to hook up to a PIC16C84. I searched at Maxim and received free samples of Max186. But it is really too expansive! I searched for another one and found the one I am using now: 3 times cheaper in quantities, 12 bits serial, about 2 1/2$. It is TLC2543 from TI. A good choice. I have got code for it too. By the way, it's a dil18 (also SMD parts) and has 11 mux analog inputs David

Did you have any problems with digital noise coupling into the analog acquisition - ie did you have to digitally filter any of the outputs ? rdgs mike perth, Western Australia
