The MAX4493/MAX4494/MAX4495 single/dual/quad general-purpose operational amplifiers are designed for use in systems powered with dual supplies from ±2.25V to ±5.5V or with a single supply of +4.5V to +11V.
The MAX4493, MAX4494 and MAX4495 are low‑power, general‑purpose operational amplifiers offered in SC70, SOT‑23 and TSSOP/SO packages. They operate from dual supplies of ±2.25 V to ±5.5 V or a single supply of +4.5 V to +11 V and are rated for automotive temperature ranges.
Key features include a 5 MHz gain‑bandwidth product, 770 µA quiescent current per amplifier, rail‑to‑rail output swing within 10 mV of the rails, 110 dB open‑loop gain and low THD+N (0.002 %). The devices are stable with capacitive loads up to 300 pF and support a variety of applications such as battery‑powered systems, DAC output stages and signal‑conditioning circuits.
