MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 is a low-power operational amplifier that operates from a single supply of +1.8V to +5.5V and draws only 750nA of supply current. It features ground-sensing inputs and a rail-to-rail output. The ultra-low supply current, low-operating voltage, and rail-to-rail output capabilities make these operational amplifiers ideal for use in single lithium ion (Li+), or two-cell NiCd or alkaline battery systems. The rail-to-rail output stage of the MAX4464/MAX4470/ MAX4471/MAX4472/MAX4474 amplifiers is capable of driving the output voltage to within 4mV of the rail with a 100kΩ load, and can sink and source 11mA with a +5V supply. These amplifiers are available in both fully com- pensated and decompensated versions. The single MAX4470, dual MAX4471, and the quad MAX4472 are unity-gain stable. The single MAX4464 and the dual MAX4474 are stable for closed-loop gain configurations of ≥ +5V/V. These amplifiers are available in space-sav- ing WLP, SC70, SOT23, µMAX®, and TSSOP packages.
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 family are micropower operational amplifiers that operate from a single +1.8 V to +5.5 V supply and draw only 750 nA per amplifier. They feature ground‑sensing inputs, rail‑to‑rail output, and can source or sink up to 11 mA, making them suitable for battery‑powered applications.
The devices are offered in several compact packages (SC70, SOT23, µMAX, TSSOP, etc.) and are available in both fully compensated and de‑compensated versions. Typical gain‑bandwidth is 9 kHz for the MAX4470/4471/4472 series and 40 kHz for the MAX4464/4474 series, with unity‑gain stability for single and dual configurations. Detailed electrical characteristics, pin descriptions, and package information are provided throughout the document.
