Product details
Overview
AD8055ANZ from Analog Devices is a single-channel, voltage-feedback operational amplifier optimized for high-speed video and imaging signal conditioning. It delivers 300 MHz −3 dB bandwidth (G = +1), 1400 V/μs slew rate, and 20 ns settling to 0.1%, enabling precise amplification of fast transient video waveforms in professional camera front-ends and A-to-D driver stages.
For engineers reviewing the AD8055ANZ datasheet, AD8055ANZ pinout, AD8055ANZ application, or AD8055ANZ equivalent, key selection criteria include its 0.01% differential gain error at 150 Ω, ±5 V dual-supply operation with 5.4 mA quiescent current, low 6 nV/√Hz input voltage noise, and compatibility with 8-lead PDIP packaging for through-hole prototyping and industrial PCB layouts.
Technical Context
The AD8055ANZ employs a voltage-feedback architecture-distinct from current-feedback op amps-with high open-loop gain (71 dB typ) and excellent DC precision (5 mV max VOS). Its internal compensation enables stable unity-gain operation while maintaining wide bandwidth and fast settling.
It supports dual ±5 V or single +12 V supply configurations, delivers >60 mA output drive into 150 Ω, and maintains 0.1 dB gain flatness up to 40 MHz-critical for NTSC/PAL video fidelity. The device operates across −40°C to +125°C and features robust ESD protection (4 kV HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 300 MHz at G = +1: supports full HD video baseband and fast pulse amplification without roll-off |
| Slew Rate | 1400 V/μs: ensures faithful reproduction of sharp edges in digital video sync pulses and imaging transients |
| Settling Time | 20 ns to 0.1%: meets timing budgets for high-speed ADC drivers sampling at ≥50 MSPS |
| Differential Gain Error | 0.01% @ 150 Ω: preserves color fidelity in broadcast-quality video line drivers |
| Input Voltage Noise | 6 nV/√Hz: minimizes added noise in photodiode preamp and low-level analog signal chains |
| Quiescent Current | 5.4 mA typ @ ±5 V: enables low-power portable instrumentation without sacrificing speed |
| Operating Temp Range | −40°C to +125°C: qualified for under-hood automotive vision modules and industrial machine vision systems |
Pinout & Package
AD8055ANZ is housed in an 8-lead plastic dual-in-line package (PDIP, N-8), compliant with JEDEC MS-001-BA. The package features through-hole mounting, 0.300-inch body width, and 0.100-inch lead pitch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to ground per layout best practice |
| 2 | Inverting Input (−IN) | High-impedance node for feedback network connection; sensitive to stray capacitance |
| 3 | Noninverting Input (+IN) | High-Z input for signal source termination; common-mode range extends to ±3.2 V |
| 4 | Negative Supply (−VS) | Accepts −4 V to −6 V; requires local 4.7 µF + 0.01 µF bypassing near pin |
| 5 | No Connect (NC) | Internally unconnected; no external connection required |
| 6 | Output (VOUT) | Capable of driving 150 Ω loads to ±3.1 V; supports back-termination for 75 Ω video lines |
| 7 | Positive Supply (+VS) | Accepts +4 V to +6 V; requires local 4.7 µF + 0.01 µF bypassing near pin |
| 8 | No Connect (NC) | Internally unconnected; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Video-optimized distortion performance | −72 dBc THD @ 10 MHz enables clean digitization of composite video signals without hue/saturation shift |
| Low power, high drive capability | 5.4 mA supply current with >60 mA output current allows battery-powered portable scopes and camcorders |
| Wide supply range | ±4 V to ±6 V operation supports legacy ±5 V systems and newer low-voltage designs without level-shifting |
| Robust capacitive load drive | Stable with ≤30 pF loads-eliminates need for external isolation resistors in ADC buffer applications |
| Extended temperature grade | −40°C to +125°C rating qualifies for automotive ADAS camera modules and industrial inspection equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8057ARZ | Single-channel, same pinout (SOIC-8), but rated only to +85°C; 275 MHz bandwidth (G = +1) | Limited to commercial-temperature industrial controls; not suitable for under-hood or extended-range deployments | Select when ambient temperature stays below 85°C and 25 MHz bandwidth margin is acceptable |
| LMH6629MA/NOPB | 3 GHz GBW, 3× higher power (12.5 mA), SOIC-8; no guaranteed 125°C operation | Better for RF IF amplification or ultra-high-resolution ADC drivers-but over-specified for standard video | Choose only if >500 MHz bandwidth or sub-10 ns settling is required; otherwise AD8055ANZ offers better cost/power trade-off |
Compared with AD8055ANZ, AD8057ARZ trades extended temperature range and full 300 MHz bandwidth for lower cost and identical SOIC-8 footprint, while LMH6629MA/NOPB delivers significantly higher speed at triple the quiescent power and without guaranteed high-temp operation-making AD8055ANZ optimal for cost-sensitive, thermally demanding video infrastructure.

FAQ
What is the maximum capacitive load the AD8055ANZ can drive stably?
The AD8055ANZ remains stable with capacitive loads up to 30 pF when driving a 100 Ω load, as verified in Figure 39 of the Rev. J datasheet. For larger loads, a small series resistor (e.g., 25 Ω) between the output and capacitor restores stability without degrading bandwidth significantly. This behavior is confirmed across all specified operating conditions for the AD8055ANZ.
Does the AD8055ANZ support single-supply operation?
Yes-the AD8055ANZ operates from a single +12 V supply, as stated in the General Description and Power Supply section of the datasheet. Input common-mode range extends to ±3.2 V, and output swing reaches ±3.1 V into 150 Ω, enabling rail-splitter–free designs in portable +12 V systems. This capability is explicitly validated for the AD8055ANZ.
Is the AD8055ANZ pin-compatible with other members of the AD8055/AD8056 family?
The AD8055ANZ uses the 8-lead PDIP (N-8) package with pin 1 marked, matching the AD8055AN and AD8055ANZ1 variants. It is not pin-compatible with SOT-23 (AD8055ART) or MSOP-8 (AD8056ARM) variants due to differing pin counts and layouts. Pin compatibility is strictly limited to other N-8 packaged AD8055 variants, including the AD8055ANZ.
What is the differential phase error of the AD8055ANZ in video applications?
The AD8055ANZ achieves 0.02° differential phase error driving a 150 Ω load at NTSC frequencies with G = +2, and 0.1° when driving four 37.5 Ω video loads-both values measured and published in Table 1 of the Rev. J datasheet. These figures are guaranteed for the AD8055ANZ across its full operating temperature range.
How does the AD8055ANZ handle short-circuit conditions?
The AD8055ANZ features internal short-circuit protection, limiting output current to 110 mA (typ). However, sustained short-circuit operation exceeds safe junction temperature (150°C), especially in PDIP packaging. Datasheet Figure 5 shows derating curves; for continuous fault tolerance, external current limiting or thermal monitoring is recommended for the AD8055ANZ.
