The EL2257, connected in voltage follower mode, -3dB bandwidth is 125MHz while maintaining a 275V/µs slew rate. With an input and output common mode range that includes ground, this amplifier was optimized for single supply operation, but will also accept dual supplies. It operates on a total supply voltage range as low as 2.7V or up to 12V. This makes them ideal for +3V applications, especially portable computers.

While many amplifiers claim to operate on a single supply, and some can sense ground at their inputs, most fail to truly drive their outputs to ground. If they do succeed in driving to ground, the amplifier often saturates, causing distortion and recovery delays. However, special circuitry built into the EL2257 allows the output to follow the input signal to ground without recovery delays.
