OP727AR-REEL

Introduction

OP727AR-REEL is a precision instrumentation-grade high-performance amplifier produced by Texas Instruments (TI). It is a high-precision and low-distortion operational amplifier. The device has a unity-gain frequency of 10MHz and integrates low-noise performance, wideband gain-bandwidth product, low distortion and low offset in one complete package.

Application Field

OP727AR-REEL can be applied in the field of linear amplification, instrumentation and op amps. It is suitable for applications that require high-precision amplification, low output offset, low distortion and wide bandwidth. For example, it can be used together with active filters, sample-and-hold circuits and ADC/DAC to realize high-precision linear amplification. Furthermore, it can be used for signal isolation, fader and buffer systems, audio level generation and frequency control.

Working Principle

The OP727AR-REEL consists of two operational amplifiers (op-amps) and a slew-rate control circuit. The two op-amps are connected in a differential amplifier configuration with a limited common-mode range. The differential amplifier has a gain of approximately 200, and the upper and lower integration limit of the common-mode input voltage range is approximately 0 and 5V. The slew-rate is independently programmable–up to 10MHz–for different applications.

The op-amps in the OP727AR-REEL are designed based on bipolar technology, which makes it insensitive to power supply noise and variations, offering higher precision and stability than many other op-amps available in the market. Since it has a wide gain-bandwidth product, it is capable of amplifying extremely high frequency signals, offering high-precision amplification performance for wide range of applications.

Advantages

The OP727AR-REEL offers a number of advantages, such as its wide gain-bandwidth product (up to 10MHz) and its wide, adjustable common-mode input range. Its operating temperature range can span from –55 to 125 degrees C, making the device suitable for wide range of operating conditions. Additionally, it is designed to have an extremely low power-supply current (typically around 2mA) and is provided in a hermetically sealed 8-pin DIP or SOIC package.

The OP727AR-REEL is also characterized by extremely low distortion, making it ideal for applications involving high-resolution signal generation, such as active filters, sample-and-hold circuits and ADC/DAC. With its low thermal drift and wide common-mode range, it can guarantee consistent and precise amplification performance even in extreme temperatures or with varying power supply levels.

Conclusion

The OP727AR-REEL is a high-performance, low-distortion op-amp designed specifically for applications in the field of linear amplification, instrumentation, and buffer systems. With its wide gain-bandwidth product (up to 10MHz), wide, adjustable common-mode input range and extremely low power-supply current requirement, it is capable of providing high-precision amplification performance in a wide range of operating conditions and temperatures.
