LMC7215/LMC7225 Micro-Power, Rail-to-Rail CMOS Comparators with Push-Pull/Open-Drain Outputs and TinyPak™ Package
The LMC7215/LMC7225 comparators provide ultra‑low supply current (0.7 µA) and operate from 2 V to 8 V, delivering rail‑to‑rail input range and high output drive (up to 45 mA). Two output configurations are available: a push‑pull stage for the LMC7215 and an open‑drain stage for the LMC7225, enabling level‑shifting and low‑power operation.
Typical performance data include propagation delay of 25 µs at 5 V, input offset voltage of 6 mV, CMRR of 80 dB, and latch‑up resistance >300 mA. The devices are supplied in TinyPak™ (5‑pin SOT‑23‑5) and 8‑pin SO‑8 packages, with detailed ordering and mechanical specifications provided.
