LM2903

LM2903 ↔ LM2903V

LM2903 (TI) — SOP-8, dual differential comparator, supply 2V to 36V (or ±1V to ±18V), input offset 2mV typical, input bias current 25nA, propagation delay 1.3μs, open-collector output. LM2903V (Run-IC) — SOP-8, dual comparator, 2-36V. Отличия: (1) input offset: TI 2mV typical / 5mV max, Run-IC — 3mV / 7mV — при precision threshold detection учесть; (2) input bias current: TI 25nA, Run-IC — 50-100nA — для high-impedance dividers (>100kΩ) добавить error; (3) propagation delay: TI 1.3μs, Run-IC — 1.5-2.0μs — для fast overvoltage detection (<10μs) проверить; (4) output saturation voltage: TI 250mV @ 4mA, Run-IC — 400mV — при TTL-level interfacing проверить. Прямая замена для general-purpose applications.
