Press Release of Dialog Semiconductor Plc dated February 23, 2005


Dialog Semiconductor Reports Fourth Quarter and Full Year 2004 Results

    KIRCHHEIM/TECK, Germany--(BUSINESS WIRE)--Feb. 23, 2005--Dialog
Semiconductor Plc (NASDAQ:DLGS)(FWB:DLG):

    --  25% annual revenue growth compared to 2003

    --  Q4 2004 revenue of EUR 31.1 million compared with EUR 27.5
        million in Q4 2003

    --  Significant progress in product diversification and winning
        new customers

    --  New partnerships established and existing ones strengthened

    --  Strong position in growing 3G markets

    Dialog Semiconductor Plc (NASDAQ:DLGS)(FWB:DLG) today reported its
fourth quarter and full year results for the period ending December
31, 2004. Revenue for the full year was up 25% over 2003, to EUR 116
million, and operating losses were down by over 50% to EUR 6.1
million. A major highlight of the year was the penetration of Dialog's
power management and audio products into the 3G handset market.
Revenues from the wireless market increased by 30% to EUR 90.6
million; revenues from automotive applications grew by 51% to EUR 11.9
million.
    Roland Pudelko, CEO & president said, "The Company had some
significant achievements during 2004. New products and partnerships
were announced and relationships with key customers were greatly
strengthened. The adoption of our new and existing power management
and audio products into 3G handset applications is particularly
noteworthy. According to market analysts the market for 3G handsets is
set to grow rapidly from 20 million in 2004 to almost 50 million in
2005."
    Pudelko added, "Due to the lower than forecast uptake by customers
of wireless ICs during Q4 2004 and the weak US dollar, we are reducing
the Company's operational costs in 2005 to ensure that they are
appropriate to our revenue levels."
    He continued, expanding on the company's achievements. "We added
new products such as our LCD drivers for wireless handsets, and the
first integrated power management IC to support the Wireless Intel
SpeedStep(R) technology. We announced a long-term collaboration with
Carl Zeiss to develop and market modules for high quality camera
phones. Finally, we won more design slots in the growing number of
handsets being designed and manufactured in Asia."
    "Taken together these achievements show we have established a
strong platform from which to exploit both new application specific
standard product (ASSP) and application specific (ASIC) opportunities
in wireless and automotive electronics. The fact that we can now
address a number of different design sockets within the wireless
handset - not just the power management and audio, but also the
embedded camera and display driver - means that we can expand Dialog
Semiconductor's footprint within the handset and therefore build
further market share in the supply of mixed signal ICs."
    The Company's annual report for the year ending December 31, 2004
is available at www.Dialog-Semiconductor.com.
