Other Parts Discussed in Thread: LMP8601
Please let me know about idea for fixed Voffset on Reduce Gain condition, detailed information is below.
----------------------------------------
・Vs: 5V and Voffset: 2.5V
・On datasheet page-23, Rr is using digital potentiometer and adjust Gain.
But when Rr value (= Gain) is change, A2 input voltage also decrease, as a result LMP8603 can not output less than Voffset.
・If change Rr to Capacitor, Vs/2 output was clear but higher Gain for customer request.
・If change LMP8603 to LMP8601 and Increase Gain condition, maybe clear but occur layout change.
----------------------------------------
If there any idea for constant output referenced Vs/2, it is great helpful.
Best regards,
