S-5470 Series www.sii-ic.com © Seiko Instruments Inc., 2012 ULTRA-LOW CURRENT CONSUMPTION PHOTOCURRENT DETECTION IC Rev.1.2_00 The S-5470 Series, developed by CMOS technology, is a photocurrent detection IC with an ultra-low current consumption.

It detects 0.7 nA typ.

photocurrent generated by an external photodiode (PD) or LED.

It also has a function to detect the difference of photocurrent level between two external photodiodes (PDs) or LEDs.

Due to its ultra-low current consumption and low
