Product details
Overview
AD8055ARZ-REEL7 from Analog Devices is a single-channel, voltage-feedback operational amplifier optimized for high-speed video and imaging applications. It delivers 300 MHz −3 dB bandwidth (G = +1), 1400 V/μs slew rate, 20 ns settling to 0.1%, 6 nV/√Hz input voltage noise, and drives ≥60 mA into 150 Ω - enabling robust NTSC video line driving with 0.01% differential gain error.
For engineers reviewing the AD8055ARZ-REEL7 datasheet, AD8055ARZ-REEL7 pinout, AD8055ARZ-REEL7 application, or AD8055ARZ-REEL7 equivalent, key selection criteria include its SOIC-8 package compatibility, ±5 V / +12 V dual/single supply operation, low 5.4 mA quiescent current, and verified performance in four-load video driver and A-to-D driver circuits per Analog Devices Rev. J specification.
Technical Context
The AD8055ARZ-REEL7 implements a classic voltage-feedback op amp architecture with high open-loop gain (71 dB typ), wide bandwidth, and fast settling-distinct from current-feedback topologies yet matching their speed. Its internal compensation ensures stability with gains ≥ +1 and supports 100 Ω–1 kΩ loads without external compensation.
Designed for signal integrity in analog front-ends, it features rail-to-rail output swing (±3.1 V into 150 Ω), low input bias current (1.2 μA max), and excellent CMRR (82 dB) and PSRR (72 dB), making it suitable for precision gain stages where DC accuracy and AC fidelity must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 300 MHz at G = +1, 160 MHz at G = +2 - enables baseband video and high-frequency signal conditioning up to 40 MHz with 0.1 dB flatness. |
| Slew Rate | 1400 V/μs at G = +1 - supports clean 4 V step response with <2.7 ns rise time, critical for pulse and imaging applications. |
| Settling Time | 20 ns to 0.1% at G = +2 - ensures accurate sampling in high-speed ADC driver configurations. |
| Differential Gain/Phase Error | 0.01% / 0.02° into 150 Ω - meets broadcast-grade NTSC video line driver requirements without post-compensation. |
| Input Voltage Noise | 6 nV/√Hz at 100 kHz - minimizes contribution to system noise floor in photodiode preamp and low-level signal amplification. |
| Quiescent Current | 5.4 mA typ at ±5 V - enables portable and power-constrained designs while maintaining full high-speed performance. |
| Output Drive Current | 60 mA min into ±2.0 V swing - drives four 75 Ω video loads (37.5 Ω total) with <0.02% differential gain error. |
Pinout & Package
AD8055ARZ-REEL7 is housed in an 8-lead SOIC_N (R-8) package, compliant with JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions. Thermal resistance θJA is 144°C/W (SOIC-8, 2-layer board).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connect - must be left floating; not internally bonded. |
| 2 | −IN | Inverting input - accepts feedback network for gain configuration (e.g., 402 Ω resistor for G = +2). |
| 3 | +IN | Non-inverting input - high-impedance (10 MΩ) node for signal source connection; common-mode range extends to ±3.2 V. |
| 4 | −VS | Negative supply rail - requires stable −5 V (or ground in single-supply mode); decoupling with 0.1 µF ceramic essential. |
| 5 | NC | No connect - must be left floating; not internally bonded. |
| 6 | VOUT | Amplifier output - capable of >60 mA drive into 150 Ω; series 75 Ω back-termination recommended for video cable driving. |
| 7 | +VS | Positive supply rail - accepts +5 V (dual) or +12 V (single); decoupling with 0.1 µF ceramic essential. |
| 8 | NC | No connect - must be left floating; not internally bonded. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed voltage-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz GBW but 12 mA IQ; requires careful layout for stability at high gains. | Better for RF IF amplification; less suited for cost-sensitive video line drivers. | Choose LMH6629MA/NOPB only when >500 MHz small-signal bandwidth is mandatory and power budget allows. |
| ADA4817-1ARMZ-R7 | Faster 1 GHz GBW, lower 4.3 nV/√Hz noise, but 13.5 mA IQ and MSOP-8 only; no SOIC-8 option. | Preferred for ultra-low-noise preamp stages in test equipment; not pin-compatible with AD8055ARZ-REEL7. | Select ADA4817-1ARMZ-R7 when noise floor is critical and SOIC-8 footprint is not required. |
Compared with LMH6629MA/NOPB and ADA4817-1ARMZ-R7, AD8055ARZ-REEL7 provides optimal balance of speed (300 MHz), power (5.4 mA), cost, and SOIC-8 compatibility for volume video and imaging applications - avoiding over-specification while meeting broadcast-grade linearity.

FAQ
What supply voltages does the AD8055ARZ-REEL7 support?
The AD8055ARZ-REEL7 operates from dual ±4 V to ±6 V supplies or a single +12 V supply. At ±5 V, typical quiescent current is 5.4 mA. The device maintains full 300 MHz bandwidth and 1400 V/μs slew rate across this range, with output swing of ±3.1 V into 150 Ω. Input common-mode range extends to ±3.2 V, allowing direct interfacing with many sensor outputs.
Is the AD8055ARZ-REEL7 pin-compatible with other SOIC-8 op amps?
The AD8055ARZ-REEL7 uses a nonstandard SOIC-8 pinout: Pins 1, 5, and 8 are NC, Pin 2 is −IN, Pin 3 is +IN, Pin 4 is −VS, Pin 6 is VOUT, and Pin 7 is +VS. It is not pin-compatible with generic SOIC-8 op amps like the OP27 or AD822. Layout must follow the exact pin mapping shown in Figure 1 of the AD8055/AD8056 Rev. J datasheet.
Can the AD8055ARZ-REEL7 drive capacitive loads?
Yes - the AD8055ARZ-REEL7 remains stable with up to 30 pF capacitive load when driving a 100 Ω load at G = +2, as verified in Figure 39 of the datasheet. For larger capacitances, add a 25 Ω series resistor (RS) between VOUT and CL, per Figure 41. This preserves 0.1 dB flatness to 40 MHz and avoids peaking in frequency response.
What is the maximum operating temperature for the AD8055ARZ-REEL7?
The AD8055ARZ-REEL7 is rated for −40°C to +125°C ambient operation (A grade). Its SOIC-8 package has θJA = 144°C/W. At 85°C ambient and 5.4 mA IQ, junction temperature rise is ~15.6°C - well within safe limits. Derating curves in Figure 5 confirm 270 mW max dissipation at 85°C ambient.
Does the AD8055ARZ-REEL7 support single-supply operation?
Yes - the AD8055ARZ-REEL7 supports single +12 V operation with input common-mode range extending to 3.2 V below +VS (i.e., down to +8.8 V) and output swing to within 1.9 V of rails. For rail-to-rail input, use a level-shifting network; for true single-supply video, bias the +IN pin to mid-supply (6 V) and AC-couple the signal.
