The MAX4434-MAX4437 series of precision op amps feature wide bandwidth, 16-bit accurate settling time 23ns and low noise/low distortion characteristics.
The MAX4434‑MAX4437 family are single‑supply voltage‑feedback operational amplifiers offering 150 MHz bandwidth, 16‑bit settling in 23 ns, and ultra‑low distortion. They are optimized for high‑speed 14‑ and 16‑bit ADC front‑ends and provide up to 65 mA output drive.
The devices are available in compact 5‑pin SOT‑23 (MAX4434/5) and 8‑pin µMAX (MAX4436/7) packages. Detailed electrical characteristics, pin configurations, and layout recommendations are included to aid PCB design and ensure stable operation.
