Integraten Operation amplifier in STM32F3030

[HWolo]

In datasheet is 6.3.22 Operational amplifier characteristics

ILOAD Drive current max 500uA.

Does this mean the amplifier cannot control the negative current?

RLOAD Resistive load min 4kOhn?

Why 4kjOhgm, for exmple curtent to 4kOhm for 2.5V is 625uA, thi increase 500uA Iload

Thanks for ansver
