Hello Zoe,
Normally I would account this to layout as parallel resistors can be an issue if the current is not split evenly as expected due to resistance from your layout. Resistance and current density could not be distributed evenly as expected. You…
Part Number: LMP8640 Hi team,
Customer feedback that when supply 5V for LMP8640. There are 1.1V voltage on IN+ and IN- pin. I was wondering if it's due to bias current and Rin. Do you have any idea about the reason? Thanks!
