Комментарии об отличиях

LMV551 ↔ RS521

LMV551 (TI) ↔ RS521 (Run-IC): Оба low-power single ОУ с R2R I/O. LMV551: GBW=3MHz, SR=1V/µs, Iq=37µA, Supply 2.7-5.5V, Vos=±3mV max, input bias current 20-38nA (биполярный вход). RS521: GBW=3.6MHz, SR=1.8V/µs, Iq=~250-300µA, Supply 2.5-5.5V, Vos=±0.8mV typ, CMOS вход (pA bias). ОТЛИЧИЯ: (1) Iq у RS521 в 7-8x ВЫШЕ (~250µA vs 37µA) — КРИТИЧНО для battery-powered. (2) LMV551 — биполярный вход (20-38nA bias), RS521 — CMOS (pA) — критично для high-Z сенсоров. (3) GBW и SR у RS521 выше. (4) Vos у RS521 лучше. Pinout SOT23-5 совпадает.
