The OP2177ARZ is a voltage feedback operational amplifier designed for applications requiring a wide bandwidth and an exceptionally low noise performance. In addition to its excellent dc specifications, its slew rate of 200V/µs is fast enough for many buffer amplifier applications. It operates from a single power supply with a wide range supply of ±2.25 V to ±18V. The high common-mode rejection ratio of the OP2177ARZ makes it well suited for use with single-supply data acquisition systems, summing amplifiers, and video line receivers. Along with its advanced technology process, the unity gain stability ensures reliable performance.

The working principle of the OP2177ARZ lies in its voltage feedback configuration that amplifies the incoming signal by an amount of gain determined by the ratio of the feedback resistors around the amplifier input and output. This voltage feedback configuration is able to amplify and preserve the input signal in the presence of common-mode signals, while simultaneously rejecting the noise they introduce. The gain of the amplifier is set by the ratio of feedback resistors and can be adjusted to obtain the desired output voltage or power. The amplifier is designed with integrated input protection circuitry to protect against high-voltage reverse polarity signals and transients. Along with the integrated output protection circuitry, the amplifier is protected against shorts to ground and power supplies.
