MAX4249-MAX4257 are low-noise, low-distortion operational amplifiers with wide supply voltage range (2.4 V), large output swing (near supply voltage), and low power consumption (400 μA). These features make them ideal for mobile and battery-powered applications that require low distortion and/or low noise.
The MAX4249‑MAX4257 family are low‑noise, low‑distortion operational amplifiers that operate from a single supply as low as 2.4 V. They are suited for portable, battery‑powered equipment, wireless communications, medical instrumentation, ADC buffers, and digital scales.
Key features include rail‑to‑rail output swing, ultra‑low THD (0.0002 % THD), quiescent current of 400 µA per amplifier, and a low‑power shutdown mode that reduces supply current to 0.5 µA. The devices are offered in space‑saving UCSP, SOT23, and HMAX® packages.
| Quiescent Supply Current per Amplifier | 400 µA |
|---|---|
| Total Harmonic Distortion | 0.0002 % THD |
| Gain‑Bandwidth Product | 22 MHz (MAX4249 series) |
| Shutdown Mode Supply Current | 0.5 µA |
Each amplifier draws 400 µA of quiescent supply current.
The devices achieve a THD of 0.0002 % with a 1 kΩ load.
In shutdown mode the supply current is reduced to 0.5 µA.
