Aehr Test Systems vs Cirrus Logic
Side-by-side comparison of AI visibility scores, market position, and capabilities
Aehr Test Systems (AEHR) reported ~$80M revenue in FY2024. Provides wafer-level burn-in and test systems for silicon carbide semiconductors used in EV powertrains and solar inverters. HQ: Fremont, CA.
About
Aehr Test Systems is a semiconductor test equipment company specializing in wafer-level burn-in and test systems, with a dominant position in testing silicon carbide (SiC) power semiconductors. Silicon carbide devices are essential components in electric vehicle inverters, solar inverters, and industrial power systems — they handle high voltages and temperatures where traditional silicon fails. Before shipping, SiC semiconductors must undergo burn-in testing at elevated voltage and temperature to screen out early-life failures, and Aehr's FOX-XP wafer-level system performs this screening more efficiently than component-level testing.
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.
