PIEZOELECTRIC PRINTHEAD ASSEMBLY WITH MULTIPLIER TO SCALE MULTIPLE NOZZLES

摘要

In an example, a piezoelectric printhead assembly includes a micro-electro mechanical system (MEMS) die including a plurality of nozzles. An application-specific integrated circuit (ASIC) die is coupled to the MEMS die by a plurality of wire bonds, wherein each of the wire bonds corresponds to a respective nozzle of the plurality of nozzles. An arbitrary data generator (ADG) on the ASIC is to provide a digital data sequence, and a multiplier is to scale multiple nozzles of the plurality of nozzles.
