ULTRA-LOW CURRENT CONSUMPTION
NORMALLY-OFF FAINT SIGNAL DETECTION IC
© SII Semiconductor Corporation, 2012-2016
Rev.1.3_01
The S-5470 Series, developed by CMOS technology, is a normally-off faint signal detection IC with an ultra-low current
consumption.
This IC has a function to detect certain current level of 0.7 nA typ., which makes it possible to detect faint signals for a
variety of electric generating devices or sensor devices. It also has a function to detect the difference of current level, and
thus detects difference between strengths of two signals input at the same time.
Due to its ultra-low current consumption and low-voltage operation, the S-5470 Series is suitable for battery-operated
small mobile device applications.
