LM6142/LM6144 17MHz Rail-to-Rail Input-Output Operational Amplifiers General Description Using patent pending new circuit topologies, the LM6142/ LM6144 provides new levels of performance in applications where low voltage supplies or power limitations previously made compromise necessary. Operating on supplies of 1.8V to over 24V, the LM6142/LM6144 is an excellent choice for battery operated systems, portable instrumentation and oth- ers. The greater than rail-to-rail input voltage range eliminates concern over exceeding the common-mode voltage range. The rail-to-rail output swing provides the maximum possible dynamic range at the output. This is particularly important when operating on low supply voltages. High gain-bandwidth with 650µA/Amplifier supply current opens new battery powered applications where previous higher power consumption reduced battery life to unaccept- able levels. The ability to drive large capacitive loads without oscillating functionally removes this common problem.
The LM6142 and LM6144 are 17 MHz rail‑to‑rail input‑output operational amplifiers designed for low‑voltage, battery‑powered applications. They operate from 1.8 V to 24 V and feature low supply current (≈650 µA per amplifier) and high gain‑bandwidth.
