The surface mounted LT-1PA01 measures just 3.05 x 2.10 x 1.10mm. It uses a photoreceptor to measure the distance to an object based on the amount of returned light. Another photoreceptor is used to detect the amount of ambient brightness.
The sensor has a very low power profile, consuming only 80uA during proximity sensing. The illuminance sensing angle is +/-45° at 50% and the sensing distance is up to 70mm with gray card.
Operating voltage is +3.3V DC. Communication with the host processor is via I2C serial communications.
Mass production is scheduled to begin in May.
