The LMC7211 is a micropower CMOS comparator available in space saving SO-8 and SOT23-5 packages. This makes the comparator ideal for space and weight critical designs. The LMC7211 provides low power, low input current, high output drive, and high common mode range, making it ideal for use in mobile devices, notebook computers, personal digital assistants, and PCMCIA cards.
The LMC7211 Tiny CMOS Comparator is offered in a space‑saving SOT23‑5 package (3.05 mm × 3.00 mm × 1.43 mm) and is intended for space‑ and weight‑critical designs such as mobile phones, PDAs and PCMCIA cards. It provides rail‑to‑rail input voltage range, push‑pull output, and is supplied in two offset‑voltage grades (5 mV or 15 mV), making it suitable for sensor interfacing, alarm and security circuits.
Key electrical characteristics include a typical supply current of 7 µA at 5 V, rise/fall times of about 0.3 µs (10 kHz, 50 pF load), propagation delays of ~4 µs at 2.7 V, and short‑circuit protection of 40 mA. The device operates over a wide supply range (2.7 V to 15 V) and offers low input current and high input impedance for precision sensing applications.
