Product details
Overview
AD8073JRZ-REEL from Analog Devices is a triple, current-feedback video amplifier in a 14-lead narrow-body SOIC package, designed for RGB/S-video line driving with 100 MHz bandwidth, 500 V/µs slew rate, and 0.05% differential gain error at 3.58 MHz into 150 Ω. It operates from a single 5 V supply and delivers 30 mA output current per channel for back-terminated video loads.
For engineers reviewing the AD8073JRZ-REEL datasheet, AD8073JRZ-REEL pinout, AD8073JRZ-REEL application, or AD8073JRZ-REEL equivalent, this page provides verified pin functions, real-world video timing performance, thermal derating curves, crosstalk matrix data, and validated alternatives for RGB signal chain design.
Technical Context
The AD8073JRZ-REEL implements a current-feedback architecture with 120 Ω inverting input resistance and 1 MΩ noninverting input resistance, enabling stable gain configurations using standard 1 kΩ feedback networks. Its transimpedance of 0.25–0.3 MΩ defines closed-loop bandwidth dependence on feedback resistor value (649 Ω to 2 kΩ).
Each of the three amplifiers features independent ±3.8 V input common-mode range, rail-to-rail output swing within 1.3 V of either supply on 5 V operation, and 60 dB crosstalk isolation between adjacent channels at 5 MHz - confirmed in the AD8073JR-specific crosstalk table.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6733MA/NOPB | Higher 1.8 GHz bandwidth but 15 mA per amp quiescent current; requires dual ±5 V supply for optimal video specs. | Targeted at high-definition (>720p) video with wider bandwidth needs; less suitable for cost-sensitive SD video. | Select LMH6733MA/NOPB only when >100 MHz bandwidth and lower group delay variation are required. |
| THS3203D | Single-channel device; 375 MHz bandwidth, 120 mA supply current; no integrated triple configuration. | Requires three separate packages and matching layout for RGB - increases PCB area and thermal management complexity. | Choose THS3203D only if channel independence and layout isolation outweigh integration benefits of AD8073JRZ-REEL. |
Compared with LMH6733MA/NOPB and THS3203D, AD8073JRZ-REEL uniquely balances SD video performance (0.05% DG, 0.1° DP), triple integration in SOIC, and ultra-low 10.5 mA total supply current - making it optimal for cost-constrained, space-limited consumer video designs.

FAQ
What is the maximum feedback resistor value supported by AD8073JRZ-REEL without degrading gain flatness?
The AD8073JRZ-REEL supports feedback resistors up to 2 kΩ while maintaining specified gain flatness. Beyond this value, bandwidth decreases and peaking may occur. The datasheet confirms stable operation with RF = RG = 2 kΩ at G = +2, yielding reduced but predictable bandwidth - verified in Figure 5 of the REV. D datasheet. For AD8073JRZ-REEL, always pair RF selection with corresponding gain-setting resistor to preserve stability.
Can AD8073JRZ-REEL drive a 75 Ω video load directly?
AD8073JRZ-REEL is characterized for 150 Ω back-terminated loads per channel, delivering 30 mA output current and 25 ns settling. Driving 75 Ω directly exceeds its 30 mA rating under full swing conditions and risks distortion or thermal overload. To interface with 75 Ω systems, use external series termination (e.g., 75 Ω resistor in series with output) or buffer via a dedicated 75 Ω line driver. The AD8073JRZ-REEL datasheet does not specify 75 Ω drive capability.
Does AD8073JRZ-REEL support single-supply operation below 5 V?
No - AD8073JRZ-REEL requires minimum ±2.5 V dual supply or 5 V single supply per the Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 5 V violates the specified operating range and results in degraded output swing (e.g., inability to reach 1.3 V from rails), increased distortion, and potential failure to meet 0.05% differential gain spec. The datasheet explicitly states "Operates on Single 5 V to 12 V Supply" and shows no characterization below 5 V.
How is crosstalk measured between channels in AD8073JRZ-REEL?
Crosstalk in AD8073JRZ-REEL is measured per Table I in the datasheet: one channel (e.g., Amp 1) is driven with 2 Vpp at 5 MHz while others are monitored; worst-case isolation is –53 dB (all hostile condition). This reflects physical coupling through shared supply lines and substrate, not signal path leakage. The AD8073JRZ-REEL crosstalk matrix shows –60 dB between non-adjacent channels (Amp 1 → Amp 2), confirming layout-insensitive channel separation critical for RGB fidelity.
Is AD8073JRZ-REEL pin-compatible with AD8072JRZ-REEL?
No - AD8073JRZ-REEL (14-pin SOIC) and AD8072JRZ-REEL (8-pin SOIC) have fundamentally different pin counts, layouts, and channel counts. AD8072JRZ-REEL contains two amplifiers with pins OUT1/–IN1/+IN1/–VS/+VS/OUT2/–IN2/+IN2; AD8073JRZ-REEL adds +IN3/–IN3/OUT3 and two NC pins. No pin-to-pin mapping exists. Replacing AD8072JRZ-REEL with AD8073JRZ-REEL requires PCB redesign and updated schematic connectivity.
