AM3354: IO questions

Part Number: AM3354
Other Parts Discussed in Thread: LM45, , OPA320

Hi,

 

A customer I support is using  an AM3354 on a board and uses one of the analog inputs to read out a LM45 temp sensor.

There is no buffer amplifier (charge bucket) in between. Do the analog inputs of the AM3354 have internal buffers or is it advicable to add an external buffer?

 

Secondly, what is the maximum sink current of the AM3354 IO pins?
