描述

The MAX4452/MAX4352 single, MAX4453/MAX4353 dual, and MAX4454/MAX4354 quad amplifiers combine high-speed performance with ultra-low power consumption. The MAX4452/MAX4453/MAX4454 are unity-gain stable and achieve a -3dB bandwidth of 200MHz, while the MAX4352/MAX4353/MAX4354 are compensated for a minimum closed-loop gain of +5V/V and achieve a 80MHz -3dB bandwidth. These devices consume only 620µA of supply current per amplifier.

These amplifiers operate from a +2.7V to +5.25V single supply and feature rail-to-rail outputs. Along with an excellent speed/power ratio of 323MHz/mA, these devices feature a slew rate of 95V/µs and fast 20ns rise and fall times. These devices are ideal for low-power/low-voltage systems that require wide bandwidth such as cell phones and keyless entry systems.

The MAX4452/MAX4352 are available in miniature 5-pin SC70 and SOT23 packages, while the MAX4453/MAX4353 are available in tiny 8-pin SOT23, thin SOT23, and SO packages. The MAX4454/MAX4354 are available in space-saving 14-pin TSSOP and SO packages.
