MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 19-2021 Rev 4 7/11 Single/Dual/Quad, +1.8V/750nA, SC70, Rail-to-Rail Op Amps General Description Features The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 Ultra-Low 750nA Supply Current Per Amplifier family of micropower op amps operate from a single Ultra-Low +1.8V Supply Voltage Operation +1.8V to +5.5V supply and draw only 750nA of supply Ground-Sensing Input Common-Mode Range current. The MAX4470 family feature ground-sensing inputs and rail-to-rail output. The ultra-low supply cur- Outputs Swing Rail-to-Rail rent, low-operating voltage, and rail-to-rail output capa- Outputs Source and Sink 11mA of Load Current bilities make these operational amplifiers ideal for use No Phase Reversal for Overdriven Inputs in single lithium ion (Li+), or two-cell NiCd or alkaline battery systems. High 120dB Open-Loop Voltage Gain The rail-to-rail output stage of the MAX4464/MAX4470/ Low 500V Input Offset Voltage MAX4471/MAX4472/MAX4474 amplifiers is capable of 9kHz Gain-Bandwidth Product driving the output voltage to within 4mV of the rail with a (MAX4470/MAX4471/MAX4472) 100k load, and can sink and source 11mA with a +5V supply. These amplifiers are available in both fully com- 40kHz Gain-Bandwidth Product pensated and decompensated versions. The single (MAX4464/MAX4474) MAX4470, dual MAX4471, and the quad MAX4472 are 250pF (min) Capacitive Load Capability unity-gain stable. The single MAX4464 and the dual Available in Tiny, 6-Bump WLP, 5-Pin SC70, and MAX4474 are stable for closed-loop gain configurations 8-Pin SOT23 Packages of +5V/V. These amplifiers are available in space-sav- ing WLP, SC70, SOT23, MAX , and TSSOP packages.
