The MAX4249–MAX4257 are low-noise, low-distortion operational amplifiers that offer rail-to-rail outputs and single-supply operation down to 2.4V.
The MAX4249‑MAX4257 family are single‑supply, low‑noise, low‑distortion operational amplifiers with rail‑to‑rail output capability. They operate from 2.4 V to 5.5 V and draw only 400 µA quiescent current per amplifier, making them suitable for portable and battery‑powered designs.
Key features include ultra‑low total harmonic distortion (0.0002 % THD), a gain‑bandwidth product of up to 22 MHz, and a low‑power shutdown mode that reduces supply current to 0.5 µA. The devices are offered in UCSP, SOT23, and HMAX packages and are qualified for automotive temperature ranges.
