Product Summary
The MAX4491AKA-T is a low-cost, high-slew-rate, rail-to-rail I/O Op amps in SC70. The MAX4491AKA-T exhibit a high slew rate of 10V/μs and a gain-bandwidth product of 10MHz. The MAX4491AKA-T can drive 2kW resistive loads to within 55mV of either supply rail and remain unity-gain stable with capacitive loads up to 300pF. Applications are (1)Battery-Powered Instruments; (2)Portable Equipment; (3)Audio Signal Conditioning; (4)Low-Power/Low-Voltage Applications; (5)Sensor Amplifiers; (6)RF Power Amplifier Control; (7)High-Side/Low-Side Current Sensors.
