The device is able to maintain high accuracy and stability even in fast changing temperature conditions.

Working Principle

The ADA4051-1ARJZ-RL is a dual-channel operational amplifier that uses a voltage feedback design. The device is composed of two sections: a differential amplifier and a voltage amplifier. The differential amplifier produces a differential input signal, which is then amplified by the voltage amplifier.The differential amplifier is composed of two input transistors and two output transistors. The inputs of the amplifier (IN+ and IN-) are the terminations of the transistors. The outputs of the amplifier (Out+ and Out-) are realized by the emitter terminals of the transistors. When an input signal is applied to the inputs of the amplifier, the transistors switch on and current flows through them. This current will be further amplified by the voltage amplifier.The voltage amplifier is composed of two positive transistors and two negative transistors, plus two current sources. The voltage amplifier boosts the differential input signal from the differential amplifier and produces a gain proportional to the current sources. The fixed bias current sources ensure that the device has a low input offset and high gain stability. The ADA4051-1ARJZ-RL also includes a number of features to reduce the effect of power supply noise on the device’s performance. These features include an on-board regulated 1.2V reference, an on-chip power supply capacitor, power supply noise-rejection circuitry, and an adjustable common-mode voltage (CMV). The CMV can be adjusted to reduce the effects of power supply noise by providing a more robust and stable reference voltage.

Conclusion

The ADA4051-1ARJZ-RL is a high-performance dual voltage-feedback operational amplifier from Analog Devices. It is an ideal choice for instrumentation, medical and process control applications due to its high accuracy, low offset drift and low noise characteristics. The device is composed of a differential amplifier and a voltage amplifier, and has a number of features to reduce the effect of power supply noise on its performance.
