Low-voltage and low-power operational amplifiers that operate with supply voltages ranging from 2.7V to 12V and have rail-to-rail input and output capability
The LMV841 (single) and LMV844 (quad) are low‑voltage, low‑power CMOS operational amplifiers with rail‑to‑rail input and output capability. They are offered in a 5‑pin SC70 package (LMV841) and a 14‑pin TSSOP package (LMV844), making them suitable for space‑constrained PCBs and portable electronics.
These amplifiers are intended for high‑impedance sensor interfaces, battery‑powered instrumentation, high‑gain stages, DAC buffers, instrumentation amplifiers, and active filters. The datasheet provides absolute‑maximum ratings, electrical characteristics at 3.3 V, 5 V, and ±5 V, typical performance curves, and ordering information.
