OPA2677H Description

The OPA2677H is a high-performance, dual-channel current feedback operational amplifier (op-amp) designed by Texas Instruments. This op-amp is known for its exceptional speed and bandwidth capabilities, making it suitable for a wide range of high-frequency applications. The OPA2677H features a gain bandwidth product of 2 GHz, which is significantly higher than many other op-amps in its class. This high gain bandwidth product ensures that the amplifier can maintain high performance across a broad frequency range, making it ideal for applications requiring fast signal processing and high fidelity.

The OPA2677H operates with a supply voltage range of 5 V to 12 V, providing flexibility in power supply requirements. It has a very low input bias current of 10 µA, which minimizes the impact of the amplifier on the input signal source. The -3 dB bandwidth of 250 MHz and a slew rate of 2000 V/µs further enhance its ability to handle high-frequency signals with minimal distortion. The OPA2677H also boasts a low input offset voltage of 800 µV, ensuring high accuracy in signal amplification.

The OPA2677H is housed in an 8-pin high-speed small outline package (8HSOP) and is designed for surface mount applications. It is RoHS3 compliant and REACH unaffected, making it suitable for environmentally conscious manufacturing processes. The amplifier can deliver up to 500 mA of output current per channel, making it capable of driving high-capacitance loads without significant degradation in performance.
