National Semiconductor LMV841/LMV842/LMV844 Datasheet
The LMV841 (single), LMV842 (dual) and LMV844 (quad) are CMOS input, rail‑to‑rail I/O operational amplifiers offered in compact 5‑Pin SC70, 8‑Pin MSOP/SOIC and 14‑Pin TSSOP/SOIC packages. They operate from 2.7 V to 12 V, making them suitable for high‑impedance sensor interfaces, battery‑powered instrumentation, DAC buffers, and active filters.
Key electrical characteristics include low supply current (≈1 mA per channel), input offset voltage as low as 50 µV typical, input bias current of 0.3 pA typical, unity‑gain bandwidth of 45 MHz, and CMRR up to 112 dB. Ordering information and package markings are provided for each device variant.
