Thu, 04 Dec 2008 16:09:57 -0800 http://backend.userland.com/rss092 hey, hello friends!wanna help to select 12 bit ADC with I2C bus.please can any of you suggest me proper ADC which is available in INDIA.and about prog <noauthor@nospam.com> http://www.8051projects.net/forum-t10464.html programming example.. i doubt but for ADC, you can try with Dallas (http://www.maxim-ic.com/). They are costly like 400rs for one IC. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t10464.html OK, is there any option for it? or I just use parallel 122 bit ADC. If yes please suggest IC.thanks. BJ<astrobhushan@nospam.com> http://www.8051projects.net/forum-t10464.html A common parallel 12 bit ADC is the ICL7109. U may get it for around rs.100.(it doesnot come any cheaper than that. ). If u r using the 89s52 uC th pdi33<islurpundalik@nospam.com> http://www.8051projects.net/forum-t10464.html hi BJ if u wud not mind SPI instead of I2C , u will get adc's of even more resolution and higher bits.try googling for CS5460A it can operate as 24 shyam<shyam@nospam.com> http://www.8051projects.net/forum-t10464.html nice one shyam bhai. will check that one out. if it works, it will solve a lot of my problems, thanks a lot. btw, is it available commonly in india? pdi33<islurpundalik@nospam.com> http://www.8051projects.net/forum-t10464.html isn't the CS5460A a energy meter IC, its called a 24 bit ADC but one can get 12-14 bits with good input filtering.to get 24 bit resolution the input h Arun Kumar V<nura1002003@nospam.com> http://www.8051projects.net/forum-t10464.html no doubt there are many chips for 12 bit ADCs available arun, but what impressed me about the IC suggested by shyam was the price which is more than a pdi33<islurpundalik@nospam.com> http://www.8051projects.net/forum-t10464.html hi PDI33Arun is right it is an energy meter.easily available in Mumbai. by the way i already have some 20+ numbers with me if u require it . one th shyam<shyam@nospam.com> http://www.8051projects.net/forum-t10464.html yep shyam, the first thing i did when i read ur prev post , i downloaded the datasheet and came to know that it is a energy meter IC. still i feel no pdi33<islurpundalik@nospam.com> http://www.8051projects.net/forum-t10464.html hello all, I studied datasheets of CS5460A and I would like to do project with it.but it is not available in our market in Pune!!!any solution?????? BJ<astrobhushan@nospam.com> http://www.8051projects.net/forum-t10464.html u can contact me if u want...i have enough of it! shyam<shyam@nospam.com> http://www.8051projects.net/forum-t10464.html
