Post by thread:PICs with A/D

Does any body know if there are other PICs with built-in A/D convertors aside from teh 16c71 ? Also would any body know where can one get Analog Devices AD620 operational amplifiers. I have tried several houses (DIGIKEY, NEWARK, etc) but non of them had the chip in stock. Thanks in advance Carlos Lopez-Reyna

It has a 16-bit A to D. I got the spec. sheet just a couple days ago. It's pretty impressive - lots of extras. -- -- Paul Greenwood -- (spam_OUTpabloTakeThisOuTaustin.ibm.com) Drive defensively.

How can I get the specs for the MTA14000 and is it already in production? Thanks Lau Hui King National University of Singapore email: doslauhkKILLspamleonis.nus.sg

Carlos: All the PIC16C7x parts contain A/D converters, and the 16C62x parts have comparators. -Andy -- Andrew Warren - EraseMEfastfwdspam_OUTTakeThisOuTix.netcom.com Fast Forward Engineering, Vista, California

I have orders for the AD590 out 23 weeks. Could you substitute the AD part with a Linear Technology LT1101? (They are not pin compatible) Mike

Just call the numbers in the back of the databooks. I don't think they are in production yet because I was told that samples wouldn't be available for a while. -- -- Paul Greenwood -- (@spam@pabloKILLspamaustin.ibm.com) Drive defensively. Buy a tank.
