Hi, ACGUY,

Since TLC59116F is not a constant current driver, there's no spec for the current accuracy.

If you need to use high accuracy, you can refer to constant current driver like LP5018.

Thanks.

Hello Keneth,

Thank you for answer quickly.

ILED(max) = 80mA neer
CHs = 8 or 16 or 24 or 32
ILED accuracy is less than ±8% between settings.

Do you know the LED driver that meets the above conditions?
