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-voltage operation, the S-5470 Series is suitable for battery-operated
small mobile device applications.
„ Features
• Ultra-low current consumption:
• Micro-photocurrent detection:
• Wide operation voltage range:
• Detection of certain photocurrent level:
I_DD ≤ 0.1 nA typ.
I_DET = 0.7 nA typ.
V_DD = 0.9 V to 5.5 V
Detects certain level of photocurrent generated by external photodiode
(PD) or LED
• Detection of photocurrent level difference: Detects the difference of photocurrent level between external
• External parts:
• Lead-free (Sn 100%), halogen-free^*2
photodiodes (PDs) or LEDs
One or two external photodiodes (PDs) or LEDs^*1
*1. The required number of PDs or LEDs changes with operation.
