FDA4100LV is fully c onfigurable through i 2 c bus interface and integrates a full diagnostics array specially intended for au tomotive applications (with the status of each single speaker). thanks to the solutions implemented to solve the emi problems, the device is conceived to be used in the standard single din car-radio box together with the tuner. the possibility to paralleliz e the outputs allows to drive both 2 ? and 1 ? speakers. a built-in step-up driver allows to provide high output power even using the standard 14 v supply voltage. moreover FDA4100LV is able to work down to 6 v supply, thus supporting the most recent low voltage ('start-stop') ca r-makers specification. hiquad-92 (slug-up) ' ! 0 ' 0 3 table 1. device summary order code package packing FDA4100LV hiquad92 tray www.st.com
