CXA2598M

CXA2598M PDIC for CD-R/RW Description The CXA2598M is a PDIC (photodetector IC) developed as a photodetector for the optical pickup of CD-R/RW. The photodiode and I-V amplifier operate at high speed (100MHz). When the strong light is emitted during write, the delay or ringing is not occurred because the limiter circuit is included in the I-V amplifier. Focus servo: astigmatic method Tracking servo: differential push-pull method Features I-V amplifier (current-voltage conversion circuit) RF output of addition of A to D signals Wide band (100MHz typ.) Output limiter circuit Small transparent molded package (SOP) Applications Optical pickup for CD-R/RW Structure Bipolar silicon monolithic IC Absolute Maximum Ratings (Ta = 25°C) Supply voltage VCC 5.5 Operating temperature Topr –10 to +70 Storage temperature Tstg –40 to +85 Allowable power dissipation PD 300 Operating Condition Supply voltage PD-S-12 (Plastic) V °C °C mW VCC 4.5 to 5.5 V Sony reserves the right to change products and specifications without prior notice.
