Sensor boosts ambient light immunity
The OPB9000 offers programmable sensitivity and output configuration (polarity/open drain/push-pull). A self-calibration function eliminates the need for constant recalibration as the LED ages. Temperature compensation and automatic gain control allow reliable operation under demanding and dynamic environmental conditions, while a response time of 6 µs ensures high-speed detection for time-critical detection tasks.
With its integrated analog front end and digital interface, the OPB9000 helps eliminate circuit complexity and reduces board space requirements by as much as 80%. The sensor combines an infrared emitter and integrated logic sensor in a miniature 4.0×2.2×1.5-mm surface-mount package.
