Product details
Overview
AD8073JRZ-REEL7 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 –3 dB bandwidth, 0.05% differential gain error, and 30 mA output current per channel into 150 Ω. It operates from a single 5 V supply and delivers 25 ns settling time to 0.1% in consumer and business video electronics.
For engineers reviewing the AD8073JRZ-REEL7 datasheet, AD8073JRZ-REEL7 pinout, AD8073JRZ-REEL7 application, or AD8073JRZ-REEL7 equivalent, this page provides verified electrical specifications, package mapping to R-14 SOIC, confirmed triple-channel video amplifier identity, real-world crosstalk data (–54 to –60 dB), and validated alternatives for RGB driver replacement scenarios.
Technical Context
The AD8073JRZ-REEL7 implements a current-feedback architecture with 120 Ω inverting input resistance and 1 MΩ non-inverting input resistance, enabling stable high-gain configurations using standard 649 Ω to 2 kΩ feedback resistors. Its transimpedance of 0.25–0.3 MΩ defines closed-loop bandwidth dependence on RF value rather than gain-setting resistor.
Each of its three amplifiers features independent +IN, –IN, and OUT terminals, rail-to-rail output swing within 1.3 V of either supply rail on 5 V operation, and internal short-circuit protection with 60–80 mA peak output current capability. The device exhibits 56 dB CMRR over ±3.8 V common-mode range and 70 dB PSRR at DC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 100 MHz at G = +2: supports full NTSC/PAL video bandwidth without attenuation. |
| Differential Gain Error | 0.05% typ at 3.58 MHz: preserves color fidelity in composite video systems. |
| Output Current | 30 mA per amplifier into 10 Ω: drives one back-terminated 150 Ω video load with margin. |
| Supply Voltage Range | ±2.5 V to ±6 V or single 5 V to 12 V: enables direct integration into 5 V video subsystems. |
| Settling Time | 25 ns to 0.1%: meets fast pixel clock timing requirements in VGA/SVGA applications. |
| Input Voltage Noise | 3 nV/√Hz at 10 kHz: minimizes noise contribution in low-level analog video signal paths. |
| Quiescent Current | 3.5 mA per amplifier: achieves 10.5 mA total for triple channel, critical for power-constrained boards. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6733MA/NOPB | Higher 1.8 GHz bandwidth but 12.5 mA per amp quiescent current; SOIC-14 pinout differs (no NC pins). | Better suited for HD/SDI pre-emphasis; less optimal for cost-sensitive SD video due to power and layout complexity. | Select LMH6733MA/NOPB only when >500 MHz small-signal bandwidth is required and thermal budget allows. |
| THS3203D | Lower 220 MHz bandwidth, 12 mA per amp, and no guaranteed 0.05% differential gain spec; SOIC-14 compatible pinout. | Valid for non-broadcast RGB but lacks documented NTSC/PAL performance validation at production volume. | Choose THS3203D for general-purpose triple op-amp use where video-grade specs are secondary to cost. |
Compared with LMH6733MA/NOPB and THS3203D, AD8073JRZ-REEL7 uniquely balances 100 MHz bandwidth, 0.05% differential gain, 3.5 mA per amplifier consumption, and SOIC-14 pin compatibility-making it the only triple video amplifier qualified for broadcast-grade SD video line driving at minimal board area.

FAQ
What is the operating temperature range for AD8073JRZ-REEL7?
The AD8073JRZ-REEL7 is specified for commercial operation from 0°C to +70°C. It is not rated for industrial (–40°C to +85°C) or extended temperature ranges. This range aligns with typical ambient conditions inside consumer video equipment enclosures and office-based computer peripherals where the AD8073JRZ-REEL7 is deployed.
Can AD8073JRZ-REEL7 operate from a single 5 V supply?
Yes, AD8073JRZ-REEL7 supports single-supply operation from 5 V to 12 V. When powered from 5 V, its outputs swing from 1.3 V to 3.7 V (1.3 V from each rail), accommodating standard 2 Vpp video signals with sufficient headroom. The –VS pin is connected to ground in this configuration, and +VS receives the 5 V supply.
What is the maximum feedback resistor value recommended for AD8073JRZ-REEL7?
The maximum recommended feedback resistor value for AD8073JRZ-REEL7 is 2 kΩ. Exceeding this value reduces bandwidth and may degrade gain flatness beyond specification. At 2 kΩ, the device maintains usable bandwidth while allowing noise bandwidth reduction in sensitive video signal chains, as confirmed in TPC 5 of the official datasheet.
How does crosstalk behave between channels in AD8073JRZ-REEL7?
AD8073JRZ-REEL7 exhibits typical crosstalk of –54 dB to –60 dB at 5 MHz depending on drive/receive channel pairing, as measured in Table I of the datasheet. Worst-case crosstalk occurs when all three amplifiers are active simultaneously (–53 dB), making it suitable for RGB systems where inter-channel isolation above –50 dB is required to prevent visible color contamination.
Is AD8073JRZ-REEL7 pin-compatible with AD8073JR-REEL7?
Yes, AD8073JRZ-REEL7 and AD8073JR-REEL7 share identical pinout, package outline (R-14 SOIC), and electrical specifications. The "Z" suffix denotes tape-and-reel packaging compliant with JEDEC J-STD-020 moisture sensitivity level 3, whereas "JR" indicates standard SOIC packaging-both are functionally and mechanically interchangeable in PCB layouts.
