The AD797BRZ is a low-cost, low-noise FET-input operational amplifier (op amp) suitable for a variety of linear applications. The high-gain, low-noise, and low-distortion characteristics make it well suited for instrumentation, high-fidelity audio, and precision systems.The AD797BRZ is a low-noise, low-distortion, high-gain amplifier suitable for a variety of linear application field. It is designed to provide high linearity, low noise and low power consumption in a wide range of operational modes. Its FET input stage offers excellent input impedance and will not degrade the signal. This makes it well suited for high-performance audio, precision systems and instrumentation.The AD797BRZ is a unity-gain stable amplifier with a typical noise level of 3nV/√Hz, low distortion and low power consumption of 100uA. The amplifier features Power-off Shutdown, conventional compensation and rail-to-rail output swing with single-supply operation. It also has two high- impedance input terminals that provide better noise performance and linearity.The AD797BRZ can operate in either a single-ended or a differential mode, with a gain of 0, 1 or -1. By changing the values of external resistors or capacitors can adjust the maximum gain and frequency response (bandwidth) to suit the application. The gain can be set to any required value within the range of 0 – 20 V/V and the maximum frequency response is equal to about 50kHz.The AD797BRZ can also be used in applications such as buffer amplifiers, instrumentation amplifiers and voltage-controlled amplifiers. It is also well suited for low-level amplification, active filters and other applications requiring high-gain and low noise performance.The working principle of the AD797BRZ is based on voltage feedback, where a feedback voltage is compared to the input voltage and amplified to the desired level. As the output voltage is always compared to the input voltage, errors introduced by the amplifier are minimized. The amplifier can also be cascoded with a high-value input impedance to provide an additional level of noise and distortion reduction.The AD797BRZ is a high-performance, low-noise and low-distortion FET-input operational amplifier that is well suited for a wide range of linear applications. With its low power consumption, low distortion and high-gain design, it is an ideal choice for audio, precision and instrumentation applications.
