Driver circuit for photodiode array with amplifier
Compact, easy-to-use driver circuit
C9118 series
PRELIMINARY DATA
Jan. 2003
C9118 series CMOS driver circuit is designed for S8865 series photodiode array with amplifier.
C9118 series operates a linear image sensor by just inputting two signals (M-CLK and M-RESET) and a signal +5 V supply. C9118 series is
assembled on a compact board measuring 48 56 mm and allows downsizing of the measurement equipment.
C9118 is intended for single use or parallel connections, while C9118-01 is suitable for cascade connections.
C9118 series does not include S8865 series photodiode array with amplifier, so select the desired photodiode array and order it separately.
