The LMV841/LMV842/LMV844 are 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. Their low offset voltage, low supply current, and MOS inputs make them ideal for sensor interface and battery-powered applications. The single LMV841 is offered in the space-saving 5-Pin SC70 package, the dual LMV842 in the 8-Pin MSOP and 8-Pin SOIC packages, and the quad LMV844 in the 14-Pin TSSOP and 14-Pin SOIC packages. These small packages are ideal solutions for area-constrained PC boards and portable electronics.
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.
