MAX4490/MAX4491/MAX4492 19-1525 Rev 2 4/01 Low-Cost, High-Slew-Rate, Rail-to-Rail I/O Op Amps in SC70 General Description Features The MAX4490/MAX4491/MAX4492 single/dual/quad, 2.7V to 5.5V Single-Supply Operation low-cost CMOS op amps feature Rail-to-Rail input and 10V/s Slew Rate output capability from either a single 2.7V to 5.5V sup- ply or dual 1.35V to 2.75V supplies. These amplifiers Rail-to-Rail Input Common-Mode Voltage Range exhibit a high slew rate of 10V/s and a gain-bandwidth Rail-to-Rail Output Voltage Swing product of 10MHz. They can drive 2k resistive loads 10MHz Gain-Bandwidth Product to within 55mV of either supply rail and remain unity- gain stable with capacitive loads up to 300pF. Unity-Gain Stable with Capacitive Loads The MAX4490 is offered in the ultra-small, 5-pin SC70 Up to 300pF package, which is 50% smaller than the standard 5-pin 50pA Input Bias Current SOT23 package. Specifications for all parts are guaran- Ultra-Small, 5-Pin SC70 Package (MAX4490) teed over the automotive (-40C to +125C) tempera- ture range.
