RA0512J

The RA0512J is designed as a full frame CCD sensor for specifically for use in astronomy, spectroscopy and related scientific imaging applications. Its combination of very low noise and low dark current make it ideal for low light level, high dynamic range and high resolution applications.

RA0512J has seven features. (1)262,144 picture elements (pixels) in a 512x512 configuration. (2)27um square pixels. (3)3-phase buried channel process. (4)On-chip output amplifier for low noise and high speed readout. (5)High dynamic range: over 98dB at -110°C (183K). (6)Serial-parallel-serial configuration for selectable bidirectional readout. (7)Usable spectral response from 450nm to 1050nm. Those are all the main features.

Some RA0512J absolute maximum ratings have been concluded into several points as follow. (1)Its storage temperature range would be from -150°C to 50°C. (2)Its pin 1,3,7,8,9,17,18,19,20,21,23,27,28,29,37,38,39,40 would be max 20V swing. (3)Its all other pins would be from 0V to 25V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some RA0512J electrical characteristics are concluded as follow. (1)Its format would be 512x512 full frame. (2)Pixel size would be 27x27um. (3)Imaging area would be 13.8x13.8mm. (4)Dynamic range would be 83,333:1 (98dB) for normal mode and would be 58,333:1 (95dB) for MPP mode. (5)Its saturation voltage would be 350mV for normal mode and would be 220mV for MPP mode. (6)Its dark current would be 1.0na/cm2 for normal mode and would be 50pa/cm2 for MPP mode. (7)Its saturation exposure would be 5.7uJ/cm2. (8)Its responsivity would be 20V/uJ/cm2. (9)Its photo-response would be typ +/-5% and max +/-10%. (10)Its output amplifier gain would be 0.5uV/electron. (11)Its read noise would be typ 6 electrons. And so on. At present we have not got so much information about this IC RA0512J and we would try hard to get more information about it.
