     Press Release of Dialog Semiconductor Plc dated December 15, 2004: 

Dialog Semiconductor Provides Trading Update for Fourth Quarter 2004

    KIRCHHEIM/TECK, Germany--(BUSINESS WIRE)--Dec. 15, 2004--Dialog
Semiconductor Plc (Nasdaq: DLGS, FWB: DLG) has announced that the weak
US dollar against the Euro is having a negative impact on the
Company's fourth quarter 2004 results. In addition the Company
experienced lower than forecast take up by customers of wireless
communication ICs. As a result of these factors, the Company expects
that gross margin for the quarter will be down approximately 8%
compared to Q3 2004. This will result in a net loss for both the
quarter and the full year and a higher than planned level of inventory
at the end of 2004. Nevertheless the Company expects to show revenue
growth of more than 20% and a reduction in operating losses for the
full year 2004 compared to 2003 of approximately 50%.
    Roland Pudelko, CEO & president commented, "After a strong
performance in the first nine months of 2004 where revenue grew 30%
over the same period of 2003, we have seen a slowdown of our revenue
growth in Q4 and our trading has been impacted by significant exchange
rate movements. In response to this changing trading environment we
have implemented a full operational review to ensure that our costs
are managed appropriately to our revenue levels."
    "During the fourth quarter of 2004 we have continued to add
customers and design wins for both our core products, such as power
management and audio ICs (integrated circuits), as well as for our
recently launched color display driver ICs. We are also maintaining
progress in our transition from an application specific IC (ASIC)
supplier to an application specific standard products (ASSPs) vendor.
Therefore we believe the prospects for growth remain positive."
