Overview
The LMH6702MAX/NOPB is a high-performance, ultra-low distortion, wideband operational amplifier designed by Texas Instruments (originally National Semiconductor). This monolithic operational amplifier is optimized for wide dynamic range systems that require exceptional signal fidelity. It benefits from National's current feedback architecture, offering unity gain stability at exceptional speeds without the need for external compensation. The LMH6702 is ideal for applications such as high-speed flash A/D and D/A converters, radar, communication receivers, and high-resolution video systems.
