Other Parts Discussed in Thread: OPA209,
Hi All,
for the opamp OPA2209AIDR can you please let me know at what forward voltage does the back to back diodes on the opamp input terminals start conducting 10mA of current?

Hello Siddharth,
The OPA209 input diodes will not conduct a current of 10 mA until the forward voltage (VF) is in excess of 0.5 V (at TA = 25 C); more likely at a level greater than 0.6 V, but less than 0.75 V. It is difficult to put an exact number on VF because it is unique to each device due to minor processing differences, and the measurement temperature. VF has a temperature coefficient around -2.2 mV/deg-C.
