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 bandwidth 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, communications, 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 compensated 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.
The MAX4412 and MAX4413 are ultra‑small, single‑supply operational amplifiers that operate from 2.7 V to 5.5 V, provide rail‑to‑rail output, and achieve a 500 MHz –3 dB bandwidth with a 140 V/µs slew rate while consuming only 1.7 mA per amplifier. They are offered in 5‑pin SC70 (MAX4412) and 8‑pin SOT‑23 (MAX4413) packages and are suited for low‑power, high‑speed portable applications such as video, communications, and instrumentation.
The datasheet includes absolute maximum ratings, DC and AC electrical characteristics, gain and phase plots, pulse‑response graphs, noise and distortion data, package outlines, pin descriptions, and application notes on driving capacitive loads and video line drivers. Revision history and ordering information are also provided.
