The LMV341/LMV342/LMV344 are single, dual, and quad low voltage, low power Operational Amplifiers. They are designed specifically for low voltage portable applications. Other important product characteristics are low input bias current, rail-to-rail output, and wide temperature range.
The LMV341/LMV342/LMV344 family provides single, dual, and quad low‑voltage, low‑power operational amplifiers designed for portable applications. They feature a patented class‑AB turnaround stage for low noise, ultra‑low input bias current (20 fA typical), rail‑to‑rail output, and a shutdown pin that reduces supply current to 45 pA typical.
These devices operate from 2.7 V to 5.5 V, cover an industrial‑plus temperature range of –40 °C to 125 °C, and are offered in compact packages (6‑Pin SC70, 8‑Pin MSOP/SOIC, 14‑Pin TSSOP/SOIC). Typical specifications include a 1.0 V/µs slew rate, 1 MHz gain‑bandwidth product, and low voltage noise (≈30 nV/√Hz at 10 kHz). Applications include portable electronics, battery monitoring, buffers, filters, and sample‑and‑hold circuits.
