OP1177/OP2177/OP4177 are precision low noise, low input bias current operational amplifiers
The OPx177 family (OP1177, OP2177, OP4177) offers very high precision single, dual, and quad operational amplifiers with ultra‑low offset voltage, low offset drift, low input bias current, and low noise. Typical applications include wireless base‑station control, optical network control, instrumentation, sensors, thermocouples, RTDs, strain bridges, and precision filters.
These amplifiers are available in surface‑mount packages such as 8‑lead MSOP, 8‑lead SOIC_N, 14‑lead SOIC_N, and 14‑lead TSSOP, and operate over a temperature range of –40 °C to +125 °C. The document includes detailed electrical characteristics, absolute maximum ratings, thermal resistance data, ESD precautions, typical performance graphs, and an ordering guide with package options.
