OP177GS – Precision Operational Amplifier with Ultra-Low Offset and Drift
The OP177GS is a high-precision operational amplifier from Analog Devices, designed for applications demanding exceptional accuracy, low noise, and long-term stability. Featuring an ultra-low input offset voltage of 10µV (max) and a near-zero drift of 0.1µV/°C, this op-amp is ideal for precision instrumentation, medical equipment, and industrial control systems. Its outstanding DC performance is complemented by a high open-loop gain of 12 million (typ), ensuring minimal error in sensitive signal conditioning circuits. The device operates over a wide supply voltage range of ±2V to ±20V, making it suitable for both low-voltage and high-voltage analog designs.
A key strength of the OP177GS is its extremely low noise performance, with a 0.1Hz to 10Hz noise density of just 0.35µVp-p, making it perfect for amplifying weak signals in data acquisition and sensor interfaces. The amplifier also exhibits excellent common-mode rejection ratio (CMRR) of 130dB (typ) and power supply rejection ratio (PSRR) of 120dB (typ), ensuring stable operation in electrically noisy environments. The OP177GS is available in an 8-pin SOIC package (GS suffix), providing a compact solution for space-constrained PCB layouts while maintaining robust thermal characteristics.
