LMH6643MM/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LMH6643MM/NOPB is a single, high-speed, low-power operational amplifier (op-amp) optimized for high-frequency applications requiring exceptional bandwidth and slew rate. Packaged in a small, space-saving 8-pin SOIC (small outline integrated circuit) with a no-lead (NOPB) finish, it operates from a single 3.3V to 5V supply, exhibiting a typical supply current of only 1.7mA. Its key specifications include a guaranteed 300MHz gain-bandwidth product and a 700V/µs slew rate, enabling faithful amplification of fast-changing signals with minimal distortion. The device features a low input bias current of 10nA (typical), minimizing input offset voltage errors, and a high input impedance, crucial for minimizing loading effects in sensitive circuits._x000D_
