NEWS RELEASE

SILICON LABORATORIES COMPLETES ACQUISITION OF INTEGRATION ASSOCIATES, DIVERSIFIED
MIXED-SIGNAL COMPANY

AUSTIN, Texas – July 30, 2008 - Silicon Laboratories Inc. (Nasdaq: SLAB) today announced it has completed the acquisition of Silicon Valley-based Integration Associates, an innovator in analog-intensive, highly integrated ICs, for $80 million net, taking into consideration Integration Associates’ net assets. Integration Associates adds a diverse portfolio of connectivity, wireless and power solutions and nearly 100 engineers to Silicon Laboratories.

“This acquisition accelerates our entry into the short-range wireless market, expands our power portfolio and adds complementary IP to augment R&D investments underway,” said Necip Sayiner, president and chief executive officer of Silicon Laboratories. “In addition to the products and revenue the company brings to Silicon Labs, we believe the Integration team is a strong technical and cultural fit, and we’re also gaining a design center in Silicon Valley, a strategic location for technical recruiting.”

The dilutive impact of the transaction in 2008 is expected to be offset by better than anticipated performance in Silicon Laboratories’ existing business. The acquisition is expected to be accretive in 2009. Integration’s products will be sold under the Silicon Laboratories brand and supported by Silicon Laboratories’ global sales and support network.
