General Description

The MAX4412 single and MAX4413 dual operational

amplifiers are unity-gain-stable devices that combine

high-speed performance, low supply current, and ultra-

small packaging. Both 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 MAX4412/MAX4413 achieve a 500MHz -3dB band-

width and a 140V/µs slew rate while consuming only

1.7mA of supply current per amplifier. This makes the

MAX4412/MAX4413 ideal for low-power/low-voltage,

high-speed portable applications such as video, com-

munications, and instrumentation.

For systems requiring tighter specifications, Maxim

offers the MAX4414–MAX4419 family of operational

amplifiers. The MAX4414–MAX4419 are laser trimmed

versions of the MAX4412/MAX4413 and include com-

pensated and uncompensated devices.

The MAX4412 is available in ultra-small 5-pin SC70 and

SOT23 packages, while the MAX4413 is available in a

space-saving 8-pin SOT23.

Inverting and Noninverting Configurations Select the gain-setting feedback (RF) and input (RG) resistor values that best fit the application. Large resistor values increase voltage noise and interact with the amplifier’s input and PC board capacitance. This can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. For example, a noninverting gain-of-two configuration (RF = RG) using 1kΩ resistors, combined with 1.

The input buffer is usually required to rapidly charge and discharge the ADC’s input, which is often capacitive (see Output Capacitive Loading and Stability).
