IntroductionOPA4703EA/2K5G4 is a high performance dual operational amplifier with very low distortion and very high common mode rejection ratio. It has a wide range of applications in audio, communication and other fields where linear performance is required.Construction and OperationThe OPA4703EA/2K5G4 is a dual, low-distortion, low-noise, and high-performance, wide-bandwidth, dual-channel, power-dissipating operational amplifier. The internal construction of the amplifier is based on a fully differential, single-ended input amplifier with a 4-stage topology and discrete MOSFET (metal-oxide-semiconductor field-effect transistor) output stage. The 4-stage architecture of the amplifier provides high performance in terms of distortion, noise and power handling.Application Fields The OPA4703EA/2K5G4 is widely used in applications such as line-level audio-processing systems including audio mixers, microphone preamplifiers, equalizers, and effects processors. In communications systems, the OPA4703EA/2K5G4 can be used for high-speed modems, line drivers, and power-level control. In instrumentation systems, it can be used for high precision sensor and bridge amplifiers, data acquisition, and analog-to-digital and digital-to-analog converters.Working PrincipleThe OPA4703EA/2K5G4 operates according to the differential amplifier principle. It is configured as two individual differential amplifiers that can be used in either a single-ended or push-pull configuration. Each amplifier provides a differential input and an output pin, which can be connected in either single-ended or differential configurations.The differential input and output pins drive the opposite side of the output stage, which is responsible for providing a gain, offset and slew rate for the amplifier. The gain is set by the amount of voltage applied to the differential inputs, while the offset is set by the power-supply voltage. The slew rate is set by the amount of current from the differential inputs to the output stage.ConclusionThe OPA4703EA/2K5G4 is a high-performance dual operational amplifier that can be used in a variety of applications that require linear performance. Its low distortion, low noise, high common-mode rejection ratio, and wide bandwidth make it a suitable choice for audio-processing, communications, and instrumentation systems.
