8.3.1 Constant Current

In LED display applications, TLC59025 provides nearly no current variations from channel to channel and from IC to IC. While IOUT ≤ 45 mA, the maximum current skew between channels is less than ±5% and between ICs is less than ±6%.

Note: When the TLC59025 is used in very low current applications, reduced current accuracy can be expected. For example, current accuracy is estimated to degrade to as much as ±10% when Iout = 1.7 mA.
