Miniature digital transducer with reduced number of external terminals

摘要

The present invention relates to miniature transducer assemblies arranged within an assembly housing having a plurality of external terminals on the assembly housing in order for the assembly to be able to receive and transmit electrical signals to and from the assembly, wherein at least one of the plurality of external terminals is adapted to receive and/or transmit at least two electrical signals so as to reduced the number of external terminals on the assembly housing. The principles apply, for example, to miniature microphone or telecoil assemblies having built-in analog-to-digital converters so as to be able to provide a digital output signal according to a sensed acoustic pressure.
