Low-Power, +3V/+5V, 400MHz Single-Supply Op Amps with Rail-to-Rail Outputs

The MAX4414–MAX4419 operational amplifiers combine high-speed performance, low distortion, and ultra-low supply current. Consuming just 1.6mA of supply current per amplifier, these devices operate from a single +2.7V to +5.5V supply, have rail-to-rail outputs, and exhibit a common-mode input voltage range that extends from 100mV below ground to within 1.5V of the positive supply rail.

The MAX4414/MAX4416/MAX4418 single/dual/quad op amps are unity-gain stable and achieve a 400MHz -3dB bandwidth with a 200V/µs slew rate. The MAX4415/MAX4417/MAX4419 single/dual/quad op amps are compensated for closed-loop gains of +5V/V or greater and achieve a 150MHz -3dB bandwidth with a 470V/µs slew rate. The combination of high-speed, ultra-low power, and low-distortion makes the MAX4414–MAX4419 ideal for low-power/low-voltage, high-speed portable systems such as video, communications, and instrumentation.

The MAX4414/MAX4415 single and MAX4416/MAX4417 dual amplifiers are available in space-saving 8-pin µMAX® and SO packages, while the MAX4418/MAX4419 quad amplifiers are available in a 14-pin TSSOP package.
