The OP177 is one of the highest precision op amps currently available. The OP177's offset voltage is only 25 μV maximum at room temperature. The ultralow VOS of the OP177 combines with its exceptional offset voltage drift (TCVOS) of 0.1 μV/°C maximum to eliminate the need for compensation of the offset voltage in precision circuits, making it an ideal differential amplifier.
The OP177 is an ultralow‑offset, bipolar‑input operational amplifier offering 25 µV maximum input offset voltage at room temperature and a drift of only 0.1 µV/°C. It provides high open‑loop gain, excellent CMRR and PSRR, and low supply current, making it suitable for high‑accuracy, high‑gain applications.
Available in 8‑lead PDIP and 8‑lead SOIC packages, the device operates from –40 °C to +85 °C and includes built‑in trim for offset adjustment. The datasheet contains detailed electrical characteristics, absolute maximum ratings, and typical performance graphs.
