EVALUATION KIT AVAILABLE MAX44264 nanoPower Op Amp in a Tiny 6-Bump WLP General Description Benefits and Features The MAX44264 is an ultra-small (6-bump WLP) op amp Ultra-Low 750nA Supply Current per Amplifier that draws only 750nA of supply current. It operates from Ultra-Low +1.8V Supply Voltage Operation a single +1.8V to +5.5V supply and features ground-sens- Ground-Sensing Input Common-Mode Range ing inputs and rail-to-rail output. The ultralow supply cur- rent, low-operating voltage, and rail-to-rail output capa- Outputs Swing Rail-to-Rail bilities make these operational amplifiers ideal for use in Outputs Source and Sink 11mA of Load Current single lithium ion (Li+), or two-cell NiCd or alkaline battery No Phase Reversal for Overdriven Inputs systems. The rail-to-rail output stage of the MAX44264 is High 120dB Open-Loop Voltage Gain capable of driving the output voltage to within 4mV of the rail with a 100k load, and can sink and source 11mA with Low 500V Input Offset Voltage a +5V supply. The IC is unity-gain stable and available in 9kHz Gain-Bandwidth Product a space-saving 0.9mm x 1.3mm, 6-bump WLP package. 250pF (min) Capacitive Load Capability Applications Available in a Tiny, 0.9mm x 1.3mm, 6-Bump WLP Cell Phones Package Tablet/Notebook Computers Mobile Accessories Ordering Information Battery-Powered Devices PIN- TOP PART TEMP RANGE PACKAGE MARK MAX44264EWT+ -40C to +85C 6 WLP +CB +Denotes a lead(Pb)-free/RoHS-compliant package. 19-5708 Rev 1 3/17MAX44264 nanoPower Op Amp in a Tiny 6-Bump WLP Absolute Maximum Ratings V to V ..............................................................-0.3V to +6V Operating Temperature Range ........................... -40C to +85C DD SS IN + or IN - ...................................(V - 0.3V) to (V + 0.3V) Junction Temperature ......................................................+150C SS DD OUT Shorted to V or V ...................................Continuous Storage Temperature Range ............................ -65C to +150C SS DD Continuous Power Dissipation (T = +70C) Lead Temperature (soldering, 10s) .................................+300C A 6-Bump WLP (derate 10.5mW/C above +70C) ........840mW Soldering Temperature (reflow) .......................................+260C Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.
