Seiko Instruments S-5470
The S-5470 Series, developed by CMOS technology, is a photocurrent detection IC with an ultra-low current consumption. 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.| Part No. | S-5470 |

FEATURES
● Ultra-low current consumption:● Micro-photocurrent detection:
● Wide operation voltage range:
● Detection of certain photocurrent level: IDD ≤ 0.1 nA typ. IDET = 0.7 nA typ. VDD = 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. Regarding selection of PD and LED, refer to "3. Selection of PD or LED" in " Application Circuits". *2. Refer to " Product Name Structure" for details.
