LM3881: long delays possibility

AlbertoP

Part Number: LM3881

For my application I need to sequence events with long delays (60 seconds, 120 seconds, etc).

Is it possible to use the LM3881 IC? Are these long delays supported by this chip in the same way of the shortest ones?

it has not been tested for such long delays over 1minutes which need 50uF capacitor. the longest test is about 2seconds.

So, I've contacted the FAE in my country in order to get a demoboard and samples and performs these tests by myself.
