Supply current is 800 µA per amplifier. ## 10 MHz GBW and 10V/µs slew — signal fidelity for audio and sensor conditioning With a 10 MHz gain-bandwidth and 10V/µs slew rate, this op-amp handles signals up to several hundred kilohertz without significant distortion. The 50 pA input bias current suits high-impedance sensor interfaces — photodiodes, piezoelectric transducers, or high-value resistor dividers — where bias current error would otherwise dominate. The 50 mA output drive is enough to directly feed a downstream ADC input or a low-power actuator. The rail-to-rail output stage maximizes dynamic range at the lower end — critical when the headroom is only a few hundred millivolts. At 800 µA quiescent current, it is efficient enough for battery-powered equipment that is not in continuous deep sleep.","metaTitle":"MAX4490AUK General Purpose Op-Amp, 10 MHz","metaDescription":"MAX4490AUK single general-purpose op-amp from Maxim Integrated. 10 MHz GBW, 10V/µs slew rate, rail-to-rail output, 2.7 V to 5.5 V supply.
