The MAX4265~MAX4270 are ultra-low distortion, voltage-feedback op amps capable of driving a 100Ω load while maintaining ultra-low distortion over a wide bandwidth.
The MAX4265–MAX4270 family are ultra‑low‑distortion, voltage‑feedback operational amplifiers that can drive a 100 Ω load while maintaining low distortion across a wide bandwidth. They are suited for high‑performance communications and signal‑processing applications and are available in both single‑channel (MAX4265, MAX4266, MAX4267) and dual‑channel (MAX4268, MAX4269, MAX4270) versions.
The devices operate from a single +4.5 V to +8.0 V supply (or ±2.25 V to ±4.0 V dual) and feature a low‑power disable mode that places the outputs in a high‑impedance state. Key performance figures include 8 nV/√Hz input voltage noise density, -90 dBc SFDR at 5 MHz, -59 dBc at 100 MHz, and up to 400 MHz -3 dB bandwidth for the MAX4265. They are offered in 8‑pin µMAX and 16‑pin QSOP packages.
