The CXA1915AN is a photo IC developed as a photo detector for the optical pickup of MiniDisc. The photodiode for RF signal detection has a built-in I-V amplifier and features low output impedance for stable output.
• Focus servo: astigmatic method
• Tracking servo: three-spot method
• Magneto optical signal (RF signal) detection: Wollaston prism method
• I-V amplifier (current-voltage conversion circuit)
• Ultra-compact transparent molded package (SSOP)
