Does anyone know if there is a major difference between the LM741 op amp and the 741CV op amp? Are they interchangeable? Also, can anyone help me find a distributer for the XR2240 timer made by Exar? I know who it is made by, I just don't know where Exar is located. Thanks for your replies.

I believe the 'C' suffix means the device is frequency compensated internally. I have never seen a non-C suffix device in use, it's plenty cheap enough to get that version. The application would determine suitability. >Also, can anyone help me find a distributer for the XR2240 timer made >by Exar? I know who it is made by, I just don't know where Exar is >located. I used this chip in a light timer once. It's available from: Circuit Specialists Inc. P.O. Box 3047 Scottsdale AZ 85271-3047 Order number is 1-800-528-1417 They have no minimum order when payment accompanies an order. The catalog number is (logically enough) XR2240C. It's $2.25 each. There's a $2.00 shipping charge. I have no connection with them except as a satisfied customer. They've always treated me well. --------------------------\ /------------------------------------------ INTERNET:tindle@ms.uky.edu | "I heard you." -Kirk BITNET:tindle@ukma.bitnet | "He simply could not believe his ears."

The "CV" in "741CV" is probably one manufacturer's designation for package type (plastic, ceramic, metal can); it is not related to compensation, as all 741's are unity-gain compensated. If memory serves, the 747 is an uncompensated 741. Isaac isw@cup.portal.com

They're interchangeable if their package styles are the same. >I believe the 'C' suffix means the device is frequency compensated internally. >I have never seen a non-C suffix device in use, it's plenty cheap enough to >get that version. The application would determine suitability. Nope - all 741's are (at least meant to be) internally compensated. The C refers to the 0-70 deg C temperature range. Jeff Winslow
