Product details
Overview
AD8051ARZ-REEL7 from Analog Devices is a single-channel, rail-to-rail output voltage feedback amplifier optimized for high-speed video and analog signal conditioning. It delivers 110 MHz −3 dB bandwidth (G = +1), 145 V/μs slew rate, 50 ns settling to 0.1%, and outputs within 25 mV of either rail at 5 V supply - enabling full dynamic range in consumer video line drivers and ADC front-ends.
For engineers reviewing the AD8051ARZ-REEL7 datasheet, AD8051ARZ-REEL7 pinout, AD8051ARZ-REEL7 application, or AD8051ARZ-REEL7 equivalent, key selection criteria include its SOIC-8 package compatibility, 4.4 mA quiescent current per amplifier, 20 MHz 0.1 dB gain flatness into 150 Ω, and verified NTSC differential gain/phase performance (0.03%/0.03°) for broadcast-grade video systems.
Technical Context
The AD8051ARZ-REEL7 employs Analog Devices' proprietary XFCB process with dielectric isolation, supporting PNP/NPN transistors with fT up to 4 GHz. Its differential-input stage minimizes nonlinear junction capacitance effects, achieving −80 dBc THD at 1 MHz into 100 Ω while maintaining low distortion across 3 V to 12 V operation.
It features a complementary common-emitter output stage with direct base drive to Q8/Q36, enabling 45 mA output current while sustaining rail-to-rail swing. Input common-mode range extends from −0.2 V to +4 V (VS = 5 V), with no phase reversal beyond rails - only ESD clamp conduction above ±0.5 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed rail-to-rail amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz GBW but 12 mA IQ; no rail-to-rail input; SOIC-8 pinout differs (Pin 2/3 swapped) | Better for RF IF amplification; unsuitable for DC-coupled video where input rail-to-rail is required | Select LMH6629MA/NOPB only when >500 MHz small-signal bandwidth is mandatory and input common-mode range ≥1 V from rails is acceptable |
| ADA4891-1ARJZ-R7 | Lower 225 MHz −3 dB BW, 160 V/μs slew, 1.2 mA IQ; SOT-23-5 package; rail-to-rail I/O | Optimized for ultra-low-power portable video; limited output drive (60 mA) and thermal derating in SOIC-8 | Choose ADA4891-1ARJZ-R7 for battery-powered handheld scopes or portable test gear where 4.4 mA IQ is prohibitive |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, AD8051ARZ-REEL7 uniquely balances 110 MHz bandwidth, rail-to-rail input/output, 45 mA drive, and SOIC-8 compatibility - making it the only option among the three qualified for NTSC-compliant composite video line driving with no layout redesign.

FAQ
What supply voltage ranges does the AD8051ARZ-REEL7 support?
The AD8051ARZ-REEL7 operates from a single 3 V to 12 V supply or dual ±5 V supplies. At 5 V, it achieves 110 MHz bandwidth and rail-to-rail output swing; at 3 V, bandwidth reduces to 70 MHz but retains 50 ns settling and 0.03% differential gain accuracy. The input common-mode range is −0.2 V to +4 V (VS = 5 V), enabling direct interfacing with most logic families and DACs without level shifting.
Is the AD8051ARZ-REEL7 pin-compatible with other members of the AD805x family?
No - the AD8051ARZ-REEL7 (SOIC-8) is not pin-compatible with AD8052 (dual, SOIC-8 or MSOP-8) or AD8054 (quad, SOIC-14/TSSOP-14). While all share identical electrical specifications per channel, pinouts differ significantly: AD8051ARZ-REEL7 uses Pins 2/3 for inputs and Pin 6 for output, whereas AD8052 places second amplifier inputs/outputs on Pins 5/6/7/8. Board-level substitution requires layout revision.
Can the AD8051ARZ-REEL7 drive 75 Ω video loads directly?
Yes - the AD8051ARZ-REEL7 delivers 45 mA output current and sustains ±4.6 V swing into 150 Ω (NTSC-qualified). For 75 Ω loads, use G = +2 with 200 Ω feedback and 75 Ω series termination at the output. Measured differential gain/phase remains 0.03%/0.03°, meeting SMPTE 170M and ITU-R BT.470 standards for broadcast video integrity.
What is the thermal performance of the AD8051ARZ-REEL7 in SOIC-8 package?
The AD8051ARZ-REEL7 in SOIC-8 has θJA = 125°C/W and θJC = 86°C/W. At 4.4 mA quiescent current and 5 V supply, power dissipation is ~22 mW. With 25°C ambient and no airflow, junction temperature rise is ~2.75°C - well within the −40°C to +125°C operating range. Derating begins above 75°C ambient per Figure 6 in the datasheet.
Does the AD8051ARZ-REEL7 require external compensation for stability?
No - the AD8051ARZ-REEL7 is unity-gain stable and requires no external compensation. It maintains phase margin >50° at G = +1 into 2 kΩ || 50 pF (Figure 15), and exhibits clean 200 mV step response with no overshoot (Figure 35). For G ≥ +2, stability is preserved with standard feedback resistor values; no capacitor across RF is needed unless driving >100 pF loads.
