The LMC6772 is a dual bipolar micropower voltage follower with open drain output. The working voltage range is wide, the output voltage range is from the positive and negative supply rails, and it is suitable for single power supply systems. The device has the characteristics of low current consumption, short circuit protection, high response speed, and is suitable for laptop computers, mobile phones, metering systems, handheld electronic devices, RC timers, alarm monitoring circuits, window comparators, etc.
The LMC6772 is an ultra‑low‑power dual comparator designed for operation over a wide supply range (2.7 V to 15 V) with rail‑to‑rail input common‑mode voltage. Its open‑drain output supports wired‑OR configurations and can be pulled up to any voltage rail up to 15 V.
Typical applications include laptop computers, mobile phones, metering systems, hand‑held electronics, RC timers and alarm circuits. The device offers short‑circuit protection, low input bias currents and optional hysteresis for noisy environments.
