The Linear-Amplifiers-Instrumentation, OP amps, Buffer amps product group is comprised of numerous devices essential to many of today\'s precision electronics applications. One device in particular, the OP481GS-REEL, is a popular and important device within this group. This article will provide an overview of the applications, as well as a review of the workings of the OP481GS-REEL.

Overview

The OP481GS-REEL is a dual operational amplifier module designed to provide high performance output power and low input offset from a minimal number of pin connections. This module is well suited to many applications where tight control of input offset is required. The module can be used for a variety of applications including AC and DC signal conditioning, data acquisition, filtering, and audio applications. In addition, this module is an excellent choice for any application requiring high bandwidth, low noise, and low power consumption.

Specifications

The OP481GS-REEL operates over a supply voltage range of ±2V to ±15V. It features a wide bandwidth of 0.2MHz (-3dB) and a wide output swing up to 10V peak-to-peak. There is a high open-loop gain of 1,000,000V/V and a low input offset voltage, (1mV over temperature). Additionally, the module has very low temperature drift and can operate at temperatures between - 55˚C to +125˚C.

Features

The OP481GS-REEL has several features that make it an attractive option for precision applications including its fast slew rate of 0.3V/µs and low total harmonic distortion of 0.01%. It also features a very low supply current of 1.2mA and a very low noise of 0.00005V RMS from 0-10KHz. The module is also internally compensated, making it easier to use in many applications.

Working Principle

The OP481GS-REEL is an integrated circuit that provides two input and two output amplifiers. It operates by taking in two input signals and amplifying them to produce two output signals with increased voltage and current. The module uses a differential amplifier topology to achieve high levels of gain. The differential amplifier takes in two input signals and subtracts the difference between them to produce a single output signal. This output signal is then amplified using an internal voltage amplifier stage to produce higher output voltage and current levels. The module then uses an output amplifier stage to provide the final output signal.

The module utilizes an advanced design for the output amplifier stage. This design includes an internal compensation network, which helps reduce the effects of output overshoot and undershoot, and a temperature-stable output stage that helps the module maintain its wide operating temperature range. Additionally, the internal protection circuitry helps protect the module from input overvoltage conditions.

Applications

The OP481GS-REEL has numerous applications in precision electronics including AC and DC signal conditioning, data acquisition, filtering, and audio applications. The module is also ideal for industrial and aerospace applications due to its wide operating temperature range, its high levels of gain, and its low power consumption. The module is also accompanied by a range of support tools and reference designs, which make it easy to incorporate into existing systems.

Conclusion

In summary, the OP481GS-REEL is an excellent operational amplifier module for precision electronics applications. It features a wide bandwidth and wide output swing, as well as low power consumption and low noise. Additionally, the module has very low temperature drift, making it suitable for applications in industrial and aerospace applications. Finally, the accompanying support tools and reference designs make it very easy to incorporate this module into existing systems.
