AD711KRZ

Introduction

The AD711KRZ is a dual, low-noise, high-speed, differential line receiver with high common-mode rejection, low distortion, and low power consumption. It is designed for applications in a variety of instrumentation, signal conditioning and professional audio equipment.

Application Field

The AD711KRZ can be used for signal conditioning, data acquisition, and for analog-to-digital or digital-to-analog conversion. It is especially suited for use in professional audio, medical imaging, and instrumentation systems. The high-speed, low-noise characteristics, combined with its wide operating temperature range of –40°C to 85°C make it ideal for a variety of applications including, but not limited to, home theatre equipment, automotive audio and video systems, and industrial process control.

Working Principle

The AD711KRZ is a differential line receiver that uses a unique architecture and proprietary circuit techniques to ensure high common-mode rejection and low distortion. The design includes several features that ensure low noise, such as integrated slew-rate control circuitry and an auto-zero amplifier that reduces offset voltage errors. The input is fully differential, with a single-ended amplifier connected to each input line.

The gain is determined by the ratio of the two input lines. The output is fully differential and has a low output impedance to ensure stable signal conditions. Output charge-carrying capacitance is minimized to limit adverse signal transmission characteristics, and a thermal pad for the output stage is integrated on the device for improved performance.

Conclusion

In summary, the AD711KRZ is a low-noise, high-speed differential line receiver with high common-mode rejection, low distortion, and low power consumption. It is designed for use in a wide range of applications in professional audio, medical imaging, instrumentation and signal conditioning systems.
