The MAX3658AETA+T is a 622Mbps, low-noise, high-gain transimpedance preamplifier in 8 pin TDFN package. The low noise, high gain and low power dissipation makes the device ideal for fibre access and small form-factor transceivers. The MAX3658 features 45nA input-referred noise, 18Kohm transimpedance gain, 580MHz bandwidth and 2mAP-P input overload. Operating from a +3.3V supply, the MAX3658 consumes only 66mW. An integrated filter resistor provides positive bias for the photodiode. It features combined with a small die size, allow easy assembly into a TO-46 header with a photodiode. The MAX3658 also includes an average photocurrent monitor. The MAX3658 has typical optical sensitivity of -33dBm (0.9A/W) which exceeds the class-B APON requirements. Typical optical overload is 1dBm. Typical applications include optical receivers (up to 622Mbps operation), passive optical networks SFF/SFP transceivers and FTTx transceivers.
- Supply voltage range is +2.97V to +3.63V
