PH503

The PH503 is designed as a 6 elements PIN photo diode built in I-V amplifiers. Photo diodes and amplifiers are integrated in one chip, so external noise can be reduced extremely. Then by using together with uPG1339G (RF amplifier and error amplifier) and uPD6353G (servo processor), it is possible to compase RF and servo block of compact disc player the most suitably.

PH503 has five features. (1)PIN photo diodes and I-V amplifiers are integrated in one chip, so external noise can be reduced. (2)+5V single supply operation. (3)It is easy to adjust the center of beam spot by using the focus and tracking input terminal. (4)Connecting two resistor can set up stable reference voltage. (5)Small transparent 16 pin plastic package. Those are all the main features.

Some absolute maximum ratings of PH503 have been concluded into several points as follow. (1)Its supply voltage would be 6V. (2)Its circuit current would be 22mA. (3)Its package dissipation would be 150mW. (4)Its operating temperature range would be from -20°C to 80°C. (5)Its storage temperature range would be from -40°C to 100°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of PH503 are concluded as follow. (1)Its circuit current would be typ 14.1mA and max 22mA. (2)Its bias voltage would be min 2.4V and typ 2.5V and max 2.6V. (3)Its reference voltage would be typ 14V. (4)Its load regulation would be max 15mV. (5)Its line regulation would be max 15mV. (6)Its input offset voltage would be typ 0.3mV and max 5.0mV. (7)Its input bias current would be max 100nA. (8)Its supply voltage rejection ratio would be min 60dB and typ 70dB. (9)Its maximum outpu high voltage would be min 3.2V and typ 3.5V. (10)Its maximum output low voltage would be typ 1.3V and max 1.6V. And so on. If you have any question or suggestion or want to know more information of PH503 please contact us for details. Thank you!
