Optoelectronic integrated circuit
The AMT128501 is a gallium arsenide optoelectronic circuit that integrates a photodetector and transimpedance amplifier. The integrated photodiode has a flat lens and an effective area of 100 microns2. The device features a monolithically integrated metal-semiconductor-metal photodetector with a transimpedance amplifier. It operates from a 5V power supply and features an 850-nm photodetector, which converts data transmitted as light over a fiber-optic network at 1.25 Gbits/sec into a differential voltage signal. The unit achieves -20 dBm or better optical sensitivity. Other features include 0-dBm overload, -3-dB bandwidth of greater than 1000 MHz, and 260-psec rise and fall times. It is available at $11 in quantities of 10,000.
