3.3V transimpedance preamplifier for optical receiver front-ends
The Maxim Integrated MAX3664EUA is a 3.3V transimpedance preamplifier designed for optical network receiver front-ends. It converts the small-signal current from a photodiode into a usable voltage, a critical first gain stage in fiber-optic links. The part is specified for surface-mount assembly in the 8-µMAX package, a space-efficient footprint for line-card and transceiver modules.
Package and supply rail
The MAX3664EUA is supplied in an 8-µMAX package, which shares the 8-TSSOP/8-MSOP (0.118", 3.00mm Width) footprint. The single 3.3V supply rail simplifies power distribution in optical modules where 3.3V is already available. Surface-mount assembly is standard; the small body suits dense PCB layouts in SFP or XFP-style modules.
Lifecycle and compliance
Note that the part is listed as RoHS non-compliant, which may affect its use in regions with strict RoHS enforcement or in new designs targeting full RoHS conformance.
