OP77GS – ANALOG DEVICES

The OP77GS is a precision operational amplifier from Analog Devices, characterized by its very low input offset voltage, typically 25 µV and a maximum of 60 µV. Input bias current is typically ±0.7 nA, with a maximum of ±4 nA, contributing to minimal DC errors in sensitive applications. The device features a high open-loop gain, typically exceeding 10 million, ensuring accurate amplification in closed-loop configurations. Slew rate is typically 0.3 V/µs, suitable for low-frequency signal processing. The OP77GS is internally compensated for unity gain stability. The “AD CUT TAPE & TUBES 2002/98” likely refers to Analog Devices’ internal tracking codes related to the specific date (2002/98) of the die fabrication and packaging process, indicating the device was supplied either in cut tape or tube packaging formats. This information is relevant for traceability and quality control within Analog Devices’ manufacturing processes.
