MAX4492

19-1525; Rev 1; 1/00 Low-Cost, High-Slew-Rate, Rail-to-Rail I/O Op Amps in SC70 General Description The MAX4490/MAX4491/MAX4492 single/dual/quad, low-cost CMOS op amps feature Rail-to-Rail® input and output capability from either a single +2.7V to +5.5V supply or dual ±1.35V to ±2.75V supplies. These amplifiers exhibit a high slew rate of 10V/µs and a gain-bandwidth product of 10MHz. They can drive 2kΩ resistive loads to within 55mV of either supply rail and remain unity-gain stable with capacitive loads up to 300pF. The MAX4490 is offered in the ultra-small, 5-pin SC70 package, which is 50% smaller than the standard 5-pin SOT23 package. Specifications for all parts are guaranteed over the automotive (-40°C to +125°C) temperature range. o 10V/µs Slew Rate o Rail-to-Rail Input Common-Mode Voltage Range o Rail-to-Rail Output Voltage Swing o 10MHz Gain-Bandwidth Product o Unity-Gain Stable with Capacitive Loads Up to 300pF o 50pA Input Bias Current o Ultra-Small, 5-Pin SC70 Package (MAX4490) Features o +2.7V to +5.5V Single-Supply Operation MAX4490/MAX4491/MAX4492 Applications Battery-Powered Instruments Portable Equipment Audio Signal Conditioning Low-Power/Low-Voltage Applications Sensor Amplifiers RF Power Amplifier Control High-Side/Low-Side Current Sensors PART Ordering Information TEMP.
