Hey, Jim, Have you worked with any high voltage analog IC processes? Like, say, 300 volts swing? I know that APEX used to have a horrible HV cmos process, maybe fabbed by AT&T or IBM or somebody improbable, but they use discretes now mostly. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

I'll thumb thru the process catalog and get back to you. (As for APEX...

They used to, I had a long discussion with them about a nice several hundred volt process. However, that was almost a decade ago and meantime they were acquired by Microchip. Clare lists up to 1000V for their processes: http://www.clare.com/Products/FabServices.htm -- Regards, Joerg http://www.analogconsultants.com/

IIRC too many $$$$. I did a chip design for Clare _many_ years ago... I'll check out their offerings. HV certainly will certainly force you into a fancier package. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | It's what you learn, after you know it all, that counts.

He's quite responsive, even though he's in Germany most of the time. Should have an answer in a day or two. ===> What kind of current handling at that voltage? ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | It's what you learn, after you know it all, that counts.

Additionally we have a fourth process with an extension in development that will be able to reach that voltage, XT018 (0.18 �m, 375 V, SOI)." John, what are your current-handling requirements? ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | It's what you learn, after you know it all, that counts.
