LMC6462/4 is a low power, operational amplifier, its input and output are rail to rail, it has very low power consumption. The LMC6462/4 input voltage range exceeds both rails. The rail-to-rail output swing of the amplifier, guaranteed for loads down to 25 kΩ, assures maximum dynamic sigal range. This rail-to-rail performance of the amplifier, combined with its high voltage gain makes it unique among rail-to-rail amplifiers. The LMC6462/4 is an excellent upgrade for circuits using limited common-mode range amplifiers. The LMC6462/4, with guaranteed specifications at 3V and 5V, is especially well-suited for low voltage applications. A quiescent power consumption of 60 µW per amplifier (at VS = 3V) can extend the useful life of battery operated systems. The amplifier's 150 fA input current, low offset voltage of 0.25 mV, and 85 dB CMRR maintain accuracy in battery-powered systems.
The LMC6462 (dual) and LMC6464 (quad) are micropower CMOS operational amplifiers offering rail‑to‑rail input and output with ultra‑low supply current. They are designed for battery‑operated, portable, and medical applications where low offset voltage and high CMRR are required.
