Title: slew rate and transistion time Post by dandelion on Jan 4th, 2007, 2:21am Hi, In some product, especiall the interface circuit it gives the transistion time(rise/fall time) spec, some gives the slew rate spec, and some gives them both. As my understanding, they descrbe the same things.So,would anyone pls. explains to me in what cases to define them in the spec? Thanks |
Title: Re: slew rate and transistion time Post by topquark on Jan 4th, 2007, 7:41am slew rate is expressed in V/s and in case of amplifiers, one has to specify the i/p (sine wave Vpp, freq etc..) and the the O/P load. In case of I/Os we just need to know the supply voltage and o/p load, when talking of rise/fall times. |
