We are using PN# ADA4898-1YRDZ in out board as a unit gain amplifier.
Refer the image for the schematic
when non inverting input is floating (pin 3) we are observing 7V at output side (pin 6).
Can you please help me;
1. why offset observed at output (pin 6).
2. can input pin left floating. will it harm the chip. (note: chip temp is normal when input is floating)
During testing measured
Non-inverting input = 10mV (floating)
Output = 7V
Project Details: Test board
Annual QTY: 1000 PCS
Thanks and Regards,
