Product details
Overview
HMC799LP3E from Hittite Microwave Corporation (now part of Analog Devices) is a DC–700 MHz transimpedance amplifier optimized for optical-to-electrical conversion in laser sensor and FDDI receiver systems. It delivers 10 kΩ transimpedance gain, 700 MHz analog bandwidth, 150 nA RMS input noise, +65 dB dynamic range, and operates from a single +5 V supply drawing 70 mA.
For engineers reviewing the HMC799LP3E datasheet, HMC799LP3E pinout, HMC799LP3E application, or HMC799LP3E equivalent, this page provides verified specifications, package layout, real-world use cases in optical receivers, and validated alternative parts for photodiode interface design with wideband, low-noise signal conditioning requirements.
Technical Context
The HMC799LP3E implements a high-gain, single-ended transimpedance architecture with internal 50 Ω output matching-eliminating external RF matching components. Its input stage is optimized for photodiode current sources with parasitic capacitance up to 3 pF, maintaining stable transimpedance across temperature (−40°C to +85°C) and supply voltage (4.5–5.5 V).
It features three independent +5 V supply pins (VCC1, VCC2, VCC3) for noise isolation, dedicated filter pins (CFILT, CEXT) for overload and reference stability, and an exposed ground paddle requiring direct PCB grounding per RF design best practices. Input referred noise density remains ≤5.6 pA/√Hz at 200 MHz under 3 pF photodiode capacitance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transimpedance amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4817-1ARZ | 1 GHz GBW op-amp; requires external feedback resistor to set transimpedance; higher input voltage noise (4.3 nV/√Hz), lower current noise density (1.1 pA/√Hz). | Better suited for ultra-low-capacitance photodiodes (<0.5 pF); lacks integrated 50 Ω output match and overload filtering. | Select when custom transimpedance values or multi-stage gain control are needed; not drop-in for HMC799LP3E's photodiode-optimized architecture. |
| HMC6000LP3E | Same 3×3 mm package, but 10 GHz bandwidth, 500 Ω transimpedance, and higher supply current (120 mA); designed for 10+ Gbps coherent receivers. | Targets next-gen optical interconnects (e.g., InfiniBand EDR); over-specified for FDDI or CATV FM where 700 MHz suffices. | Choose for future-proofing or migration to higher data rates; requires revised power delivery and thermal management. |
Compared with ADA4817-1ARZ and HMC6000LP3E, the HMC799LP3E offers optimal balance of bandwidth, noise, and integration for 125–622 Mbps optical links-delivering plug-and-play photodiode interfacing without external matching or bias tuning.

FAQ
What is the maximum photodiode capacitance supported by the HMC799LP3E?
The HMC799LP3E maintains stable transimpedance performance with total input parasitic capacitance (Cpd) up to 3 pF-including photodiode junction capacitance, PCB trace capacitance, and package parasitics-as confirmed by noise and bandwidth measurements across Cpd = 0–3 pF at 200 MHz and 700 MHz. This allows direct interface to common high-speed PIN photodiodes without external compensation.
Does the HMC799LP3E require external output matching components?
No. The HMC799LP3E features an internally matched 50 Ω output stage, verified by ≥16 dB output return loss at 500 MHz. This eliminates the need for external matching networks, enabling direct connection to 50 Ω test equipment, spectrum analyzers, or downstream limiting amplifiers-reducing bill-of-materials and layout complexity in optical receiver designs.
What is the operating temperature range for the HMC799LP3E?
The HMC799LP3E is specified for continuous operation from −40°C to +85°C ambient temperature. Electrical performance-including transimpedance gain, noise, and output return loss-remains stable across this range, as demonstrated in characterization plots showing minimal deviation in gain vs. temperature and noise vs. temperature curves from −40°C to +85°C.
How many supply pins does the HMC799LP3E have, and why?
The HMC799LP3E has three independent +5 V supply pins (VCC1, VCC2, VCC3) to isolate noise between functional blocks-input stage, gain core, and output driver. This architecture minimizes supply-induced crosstalk and improves power supply rejection ratio (PSRR), critical for maintaining signal integrity in high-dynamic-range optical receivers where supply ripple could modulate photocurrent signals.
Is the HMC799LP3E pin-compatible with other Hittite transimpedance amplifiers?
The HMC799LP3E uses a unique 16-lead 3×3 mm QFN package with specific pin assignments (e.g., CFILT on Pin 2, CEXT on Pin 4, RFIN on Pin 3). While physically similar to other Hittite LP3E packages, its pinout differs from alternatives like HMC6000LP3E-making it not pin-compatible. PCB layout must follow the exact HMC799LP3E pin map provided in the datasheet.
