What are the specs on the ADL5330 1.5V VREF output pin?

Question asked by Dan-G on Aug 13, 2014

Hi,

I'm looking to perhaps use the 1.5V VREF output pin on the ADL5330 VGA to provide a reference voltage to another chip within my AGC circuit instead of having a special reference just for it. But I know nothing about the specs.

The datasheet contains nothing about it except "Voltage Reference. Output at 1.5 V; normally ac-coupled to ground".  It says nothing on whether it can be used externally, or what loading is acceptable without using a high impedance buffer, or its noise characteristics. Does anyone know?

Regards and thanks,
Dan
