The TLE2081ACP is a precision monolithic current feedback operational amplifier. This amplifier is specifically designed for high bandwidth applications requiring high speed, low noise and low distortion. This device is ideally suited for use in audio systems, speech processing, video signal processing, digital and analog communications and control systems.The TLE2081ACP has a very fast slew rate of 115V/μs, and a wide common mode input voltage range of ± 7.5V. This operational amplifier is designed to operate with a single 5V or dual ± 2.5V supply and features excellent phase margin at unity gain (90° phase margin and gain of 0.98). The output of the amplifier is protected against short circuit conditions up to the supply voltage.The TLE2081ACP is designed to offer high speed performance while providing excellent DC accuracy, low power consumption and stable operation over a wide temperature range. The amplifier features low input offset voltage of 1mV maximum, drift coefficient of 3μV/°C, and low noise of 1.2nV√Hz.Working PrincipleThe TLE2081ACP incorporates a multi-stage design consisting of an input differential amplifier, an input gain stage and an output buffer stage. The current feedback transimpedance amplifier reduces the bandwidth of the amplifier and allows for operation from a single supply. An internal fixed gain resistor is used to ensure stability at high frequencies.The input differential amplifier is the heart of the TLE2081ACP, providing a high input impedance and low input current for low noise performance. The input gain stage provides the gain control for the amplifier. This gain stage has a loop linearization circuit that optimizes its performance and minimizes gain errors.The output buffer stage provides a low output impedance, allowing the TLE2081ACP to drive loads up to 500 ohms. The output of the amplifier is protected against short circuit conditions up to the supply voltage.ConclusionThe TLE2081ACP is an ideal high performance operational amplifier for many applications. It features excellent DC accuracy, low power consumption, high speed performance, high bandwidth, and low distortion. Its wide common mode input voltage range, fast slew rate and protection against short circuit conditions make the TLE2081ACP an attractive solution for various applications in audio systems, video signal processing, digital and analog communications, and control systems.
