HMC799LP3E

HMC799LP3E v00.0909 DC - 700 MHz, 10 kOhm TRANSIMPEDANCE AMPLIFIER Typical Applications The HMC799LP3E is ideal for: • Laser Sensor Features 10 kOhm Transimpedance Very Low Noise: 150nA Input RMS Noise over 700 MHz Bandwidth 700 MHz Analog Bandwidth 12 TRANSIMPEDANCE AMPLIFIERS - SMT • FDDI Receiver • CATV FM Analog Receiver • Wideband Gain Block • Low Noise RF Applications Wide Dynamic Range: +65 dB Low Power: 70mA from Single +5V Supply 16 Lead 3x3 mm SMT Package: 9mm2 Functional Diagram General Description The HMC799LP3E is DC to 700 MHz Transimpedance amplifier designed for opto-electronic laser sensor applications, FDDI receivers and receiver systems employing optical to electrical conversion. This amplifier provides a single-ended output voltage that is proportional to an applied current at its input port. This current is typically provided by a photodiode. Operating from a single +5V supply, HMC799LP3E features very low input referred noise, and very large electrical input dynamic range exceeding 65 dB. 10 kOhm or 80 dB-Ohms transimpedance gain provides very good sensitivity at higher data rates. The output of HMC799LP3E is internally matched to 50 ohms. External matching is not necessary. The HMC799LP3E exhibits excellent gain and output power stability over temperature, while requiring a minimal number of external bias components.
