LMC6484 is a CMOS quad rail-to-rail input and output operational amplifier. It provides a wide common-mode range and excellent accuracy, making it ideal for data acquisition systems that require a large input signal range. LMC6484 is also an excellent upgrade for circuits using limited common-mode range amplifiers such as TLC274 and TLC279. It ensures maximum dynamic signal range in low voltage and single supply systems with its rail-to-rail output swing. The LMC6484's rail-to-rail output swing is guaranteed for loads down to 600Ω. Its low voltage characteristics and low power dissipation make it especially suitable for battery-operated systems.
The LMC6484 is a CMOS quad operational amplifier that provides rail‑to‑rail input and output performance, low offset voltage, ultra‑low input bias current, and high CMRR. It is suited for data‑acquisition, handheld instruments, medical devices, and as a replacement for older rail‑to‑rail amplifiers.
