Overview
The HMC799LP3E from Analog Devices Inc. is a high-performance transimpedance amplifier designed to operate from DC to 700 MHz. This amplifier is particularly suited for opto-electronic laser sensor applications, FDDI receivers, CATV FM analog receivers, wideband gain blocks, and low noise RF applications. It operates from a single +5V supply and features a low power consumption of 70 mA. The HMC799LP3E provides a single-ended output voltage proportional to the applied current at its input port, typically from a photodiode. It is known for its very low input referred noise and a large electrical input dynamic range exceeding 65 dB.
