Cohu vs Cirrus Logic
Side-by-side comparison of AI visibility scores, market position, and capabilities
Mid-size semiconductor test handler and contactor specialist; ~$500M revenue. ABTS and Neon thermal test handler platforms serve mobility, automotive, and data center SoC testing.
About
Cohu Inc. was founded in 1947 in Poway, California and has grown into a leading mid-size provider of semiconductor test equipment through organic development and acquisitions. The company focuses on test handlers (which position chips in automated test systems), contactors (which make electrical contact between chips and test sockets), thermal management during test, and integrated test cell solutions. Cohu is a complement to ATE vendors like Teradyne and Advantest, providing the mechanical handling infrastructure that feeds chips into testers at high volume.\n\nCohu's product portfolio includes the ABTS (Automated Burn-in and Test System) platform, the Neon thermal handler for extreme temperature testing (-55°C to +165°C), and a comprehensive contactor library for BGA, QFP, and advanced packaging formats. Key served markets include automotive (ADAS, power management), mobility (smartphone application processors, modem chips), and data center (SoC, memory interface). Automotive reliability testing is a major growth driver, as automotive-grade chips require extensive burn-in and temperature cycling per AEC-Q100 standards.\n\nCohu acquired Xcerra in 2018 to significantly expand its handler product line and global service network. The company reported approximately $500 million in revenue, with margins impacted by semiconductor capital equipment cycles. As automotive electrification and ADAS content per vehicle grow, Cohu's thermal test handler business is expected to see sustained demand growth.
Austin-based audio chip leader with ~82% revenue from Apple; high-performance smart codecs, amplifiers, and haptic drivers in iPhone and MacBook power a $1.8B revenue base.
About
Cirrus Logic was founded in 1984 in Austin, Texas and has become the dominant supplier of high-performance audio chips to Apple. The company's digital-to-analog converters (DACs), analog-to-digital converters (ADCs), smart codecs, Class D audio amplifiers, and haptic feedback drivers are designed into every iPhone generation, providing the audio circuitry for the speaker, microphone, and headphone subsystems. Approximately 82% of Cirrus Logic's revenue comes from Apple.\n\nCirrus Logic's products are differentiated by their low-power, high-fidelity audio performance and integration of signal processing intelligence, including always-on voice activation and noise suppression. The company has expanded from audio into haptic actuator controllers and is developing mixed-signal IP for wearables, hearables (AirPods), and automotive infotainment. Revenue was approximately $1.8 billion in FY2025, reflecting Apple's continued premium device volume.\n\nWhile the concentrated customer base creates risk, Cirrus Logic's deep technical collaboration with Apple and long design cycle times (2–3 years for new device sockets) create strong customer stickiness. The company has been expanding its product roadmap into sensing and power management to reduce Apple dependency. Cirrus Logic is publicly traded (CRUS) and operates a fabless model, outsourcing manufacturing to foundries including TSMC and GlobalFoundries.
