AD8397ARDZ contains two voltage - feedback operational amplifiers by ADI

Functions

• Dual Operational Amplifier: The AD8397ARDZ contains two voltage - feedback operational amplifiers, which can drive heavy loads with excellent linearity.
• Rail - to - Rail Output: Its common - emitter, rail - to - rail output stage exceeds the output voltage capability of typical emitter - follower output stages. When driving a 25Ω load, the swing can reach within 0.5V of either power supply rail.
• Low Distortion: Fabricated with Analog Devices' high - speed extra - fast complementary bipolar high - voltage (XFCB - HV) process, the high bandwidth and fast slew rate of the AD8397ARDZ keep distortion to a minimum.
• High Output Current and Wide Dynamic Range: It has the characteristics of low distortion, high output current, and wide output dynamic range, which makes it very suitable for applications that require large - signal swings on heavy loads.
• Wide Supply Voltage Range: It can operate in a wide supply voltage range from 3V to 24V (or ±1.5V to ±12V in dual - supply mode).
• High - Speed Performance: It has a relatively high gain - bandwidth product and a fast slew rate. For example, the typical slew rate is 53V/μs at (Vout = 4.0Vp - p).
• Low Noise: It has low noise characteristics, which can provide high - precision amplification in sensitive applications, with a noise density of 15nV/√Hz10.
• Single - Supply or Dual - Supply Operation: It can operate in both single - supply and dual - supply modes. In single - supply mode, it is easy to use and suitable for applications where reducing design complexity is crucial.

Applications

• Twisted - Pair Line Drivers: Due to its high - speed, low - distortion, and high - output - current characteristics, the AD8397ARDZ is suitable for use as a twisted - pair line driver to transmit signals over twisted - pair cables.
• Audio Applications: It is widely used in audio applications. For example, in high - performance audio amplifiers, it can accurately amplify audio signals with low distortion and drive large - load speakers, ensuring high - quality sound output.
• General - Purpose AC Applications: The AD8397ARDZ can be used in various general - purpose AC applications, such as in some circuits that require amplification and processing of AC signals, taking advantage of its wide bandwidth, high - speed, and low - distortion characteristics.
