Fine Jeff our application is not so speed intensive on the AtoD but we do have to implement an FIR, our main restriction on the speed is also that the atod value has to be produced over modbus so comms speed tends to be the major restriction. We did a lot of timing tests when we started the project before christmas if you like i could send them to you. i could also send you the ssp code although with the 125x sharing the data line with the dataready, we use an external int to pick up the dataready and then just squirt 3 characters up the spi and to get the 24 bits of data back so not sure if relevant. paul
