ONET2804TLP Overview
The ONET2804TLP device is a high-gain, limiting transimpedance amplifier (TIA) for parallel optical interconnects with data rates up to 28 Gbps. The device is used in conjunction with a 750-μm pitch photodiode array to convert an optical signal into a differential output voltage. An internal circuit provides the photodiode reverse bias voltage and senses the average photocurrent supplied to each photodiode.
