SM8145A
NIPPON PRECISION CIRCUITS—6
TYPICAL APPLICATIONS
I
EL size: 20 + 20cm2, Current consumption: 20 + 20mA
I
EL size: 20 + 30cm2, Current consumption: 20 + 30mA
I
EL size: 10 + 30cm2, Current consumption: 10 + 30mA
Note: Connect a 1k
Ω resistor to protect IC when the EL is over 20cm2 per channel.
Note: Do not operate the SM8145A with the EL NOT connected (no load to OUTCOM/OUT1/OUT2) since the IC will be damaged.
