Other Parts Discussed in Thread: AFE4404EVM, AFE4950, AFE4404, AFE49I30,
Hi,
I have bought AFE4404EVM from your company. According to the data table, its LED current is 0-50mA (the maximum can be extended to 100mA), but actually the current is below 10mA when we use it to test blood oxygen concentration. Now I plan to buy AFE44S30EVM, according to the data table, The LED current range of this product is 25-250mA. The LED current range of other models, such as AFE4950 and AFE49i30, is 25-250mA. Why is this current range so different from that of AFE4404? If I want to use AFE44S30, can the LED work properly under a current of less than 25mA or 10mA? We also wondered how such a large current could be applied to any situation.
Looking forward to your reply, thank you!
