Overview
The LMH6702MF/NOPB is a high-performance, wideband operational amplifier designed by Texas Instruments. This DC-coupled monolithic op amp is optimized for wide dynamic range systems that demand exceptional signal fidelity. Utilizing current feedback architecture, the LMH6702 offers unity gain stability at high speeds without the need for external compensation. It is particularly suited for applications requiring low harmonic and intermodulation distortion, such as high-speed flash A-D and D-A converters, radar, and communication receivers.
