Product details

Single-supply general-purpose op-amp in a SOT-23-5

The input offset voltage is rated at 1.5 mV, input bias current at 50 pA, and each channel can source or sink 50 mA. 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.

Frequently asked questions

Where can I buy MAX4490AUK and what is the price?

The MAX4490AUK is available to order through independent distribution. Submit a request for a firm quote on your required quantity.

Does MAX4490AUK support rail-to-rail output?

Yes, the output stage is push-pull rail-to-rail, allowing the output voltage to swing within millivolts of both supply rails. This maximizes dynamic range in low-voltage single-supply designs.

What is the difference between MAX4490AUK and MAX4491?

The MAX4491 is the dual-channel version of the same amplifier core. The MAX4490AUK is a single-channel device in a SOT-23-5 package, while the MAX4491 packs two amplifiers in a larger package. Electrical specs (GBW, slew rate, supply range, output drive) are identical per channel.
