It is good for multiple light source applications, such as laser base projectors. The three sets of gain registers can be used to adjust optical-to-electrical conversion gain for each RED (R), GREEN (G), and BLUE (B) laser or any wavelength in the spectral range for the application. The ISL58344 is a single die device that has four identical photo detectors arranged in segments that are optimized for laser beam spot alignment. Quad segments can be used as a single photo diode for optical power calibration and gamma correction. The detectors can also be split into two sections with subtraction signal output for laser beam position alignment. Beam detection can also be used to compensate for MEMS scanning projector geometric distortions and temperature distortions. Registers can be updated in real time while device is in operation. • Sensitive from 400nm to 1000nm with Patented Technology for Improved Blue Photo Response The ISL58344 can be put in sleep mode through serial interface, where it consumes virtually no power. The ENA pin, when low, will put the device in standby mode. Toggling the ENA pin Hi will turn the device on quickly. • White Balance for LCoS and MEMS Systems • Differential Voltage Output • Internal Output Reference or External Output Reference • Single +3.3V Power Supply • Serial Interface for Gain Calibration • Fast Settling Time <20ns • Wide Signal Bandwidth >50MHz • Wide Signal Gain Dynamic Range >25dB • Sleep Mode for Conserving Power • Quad PD Segments Provide Laser Beam Offset for Beam Realignment Capability • Small 9-ball Optical Chip Scale Package (OCSP) (2.2mmx2.2mm) • Glass Top Package Compatible with Near UV and Blue LDs The ISL58344 operates from a single +3.3V supply.
