The MAX3266 and MAX3267 are 1.25Gbps and 2.5Gbps, low-noise fiber optic receivers with a single +3.0V to +5.5V supply voltage and no compensation capacitor.
The MAX3266 and MAX3267 are transimpedance preamplifiers designed for 1.25 Gbps and 2.5 Gbps LAN fiber‑optic receivers. Both operate from a single +3.0 V to +5.5 V supply, require no compensation capacitor, and include a space‑saving filter that provides positive bias to the photodiode through a 1.5 kΩ resistor.
Key features include ultra‑low input‑referred noise (200 nA for MAX3266, 500 nA for MAX3267), high bandwidth (920 MHz and 1.9 GHz respectively), and 1 mA input overload capability. The devices are offered in 8‑pin SO packages that can be mounted on TO‑46 or TO‑56 headers, and Maxim provides free samples and technical support via its website or phone.
