The OPA2171AIDGK is a monolithic, high-speed, JFET-input operational amplifier designed with Texas Instrument’s high voltage bipolar process. OPA2171 is a type of nanoWatt op amp from Texas Instrument’s family of ultra-low power, high performance CMOS op amps, such as the OPA2171AIDGK.

It has a wide range of features, such as wide supply range (2.7 V to 20 V), low voltage noise (1.1 nV/sq.Hz), low zj voltage drift over time and temperature (0.1 uV/°C) and low quiescent current for power saving (450 nA). It also has fast settling time to 1% error band: 0.2 us. It has superior AC parameters like low harmonic distortion (-111 dBc) and high common mode rejection ratio (90 dB). OPA2171 can also operate with a single 3.3 V supply and is free from phase reversal in power-up and power-down conditions, making it ideal for a variety of precision applications.

Application Field: OPA2171 is used to amplify small signals in very low noise environments. It finds applications in communication systems, consumer electronics, instrumentation, and audio amplifiers. Its superior AC performance makes it ideal for applications like data acquisition systems, optical communications and medical equipment. Its low voltage noise and high common mode rejection ratio make it ideal for operational amplifiers with precision requirements.

Working Principle: OPA2171 op amp operates by taking a differential input signal and providing an amplified version of the same signal through an output stage. The differential input signal is routed through a series of stages which enhance the signal, reduce distortion and noise, increase the gain and provide feedback, which helps to keep the output signal stable and consistent. The first stage of the op amp is a differential amplifier, which amplifies the input voltage, and then the signal is passed through an internal frequency compensation network, which helps to reduce distortion and noise. The next stage is a feedback amplifier, which amplifies the signal from the differential stage and then applies negative feedback to reduce distortion and noise. The final stage is a common source amplifier, which amplifies the signal from the feedback amplifier and provides it to the output stage. The output stage also provides impedance buffering, which reduces the output impedance, and impedance matching with the load.

The OPA2171AIDGK is an ideal choice for many applications due to its high performance, low power, and high precision. It provides an easy solution for applications requiring low power op amps with precision requirements, such as data acquisition and optical communication systems. Its wide supply range and low drift make it suitable for a variety of applications. Its fast settling time and low harmonic distortion make it suitable for audio applications. OPA2171AIDGK is an excellent choice for many high performance applications.
