Transimpendance amplifier
The AMT128503 is a monolithically integrated metal-semiconductor-metal diode and transimpedance amplifier for use in 850-nm Gigabit Ethernet and fiber channel applications, converting optical signals into electrical pulses. It has a typical sensitivity of -22 dBm and a minimum responsivity of 1000 V/W with a total power dissipation of approximately 120 mW. The device includes an on-chip automatic gain-control circuit letting it handle optical input powers up to 0 dBm. It operates on a +3.3 V supply ±5%, from 0°C to 70°C.
