Product details
Overview
AD8058ARMZ from Analog Devices is a dual, voltage-feedback operational amplifier in an 8-lead MSOP package, delivering 325 MHz −3 dB bandwidth (G = +1), 1000 V/µs slew rate, and 7 nV/√Hz input voltage noise. It operates from ±1.5 V to ±6 V supplies and targets high-speed analog signal conditioning in imaging, video filtering, and ADC driver applications.
For engineers reviewing the AD8058ARMZ datasheet, AD8058ARMZ pinout, AD8058ARMZ application, or AD8058ARMZ equivalent, this page provides verified specifications, validated pin functions, real-world use cases in professional video and data acquisition systems, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The AD8058ARMZ implements a voltage-feedback architecture optimized for wide bandwidth and low distortion-achieving −85 dBc THD at 5 MHz with 2 Vp-p output into 1 kΩ. Its dual-channel layout enables matched performance across channels, with −60 dB crosstalk at 5 MHz and differential gain error of 0.01% (NTSC, RL = 150 Ω).
It supports rail-to-rail output swing capability (±3.9 V into 150 Ω) and drives up to 30 pF capacitive loads without external compensation. Input common-mode range extends to ±4.0 V under ±5 V supplies, enabling direct interfacing with legacy video and sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 325 MHz at G = +1 (±5 V, 0.2 Vp-p): enables baseband video and high-speed data acquisition up to ~200 MSPS. |
| Slew Rate | 1000 V/µs (typical): supports clean 2 V step response in ≤30 ns, critical for fast-settling ADC drivers. |
| Input Voltage Noise | 7 nV/√Hz at 100 kHz: preserves SNR in photodiode preamps and low-level analog front-ends. |
| Total Harmonic Distortion | −85 dBc at 5 MHz, 2 Vp-p, RL = 1 kΩ: meets broadcast-grade NTSC/PAL video linearity requirements. |
| Supply Current per Amplifier | 14 mA typical at ±5 V: balances speed and power for dual-channel portable or space-constrained designs. |
| Differential Gain/Phase Error | 0.01% / 0.15° (NTSC, RL = 150 Ω): ensures color fidelity in professional camera filters and composite video paths. |
| Capacitive Load Drive | 30 pF (30% overshoot): allows direct connection to coaxial cables or ADC input capacitance without series isolation resistors. |
Pinout & Package
AD8058ARMZ is housed in an 8-lead Mini Small Outline Package (MSOP), JEDEC MO-187-AA compliant, with 0.65 mm pitch and 3.0 mm × 3.0 mm body size. Thermal resistance θJA = 200°C/W enables operation up to +85°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 Output | Low-impedance, rail-to-rail capable output; drives 150 Ω video loads or ADC inputs directly. |
| 2 (–IN1) | Inverting Input, Amp 1 | High-impedance node (10 MΩ); requires short trace routing to minimize parasitic capacitance-induced peaking. |
| 3 (+IN1) | Noninverting Input, Amp 1 | DC-coupled input with ±4.0 V common-mode range under ±5 V supply; accepts bipolar video signals. |
| 4 (–VS) | Negative Supply Rail | Connects to system ground or negative rail; must be bypassed with 0.1 µF ceramic + 10 µF tantalum near pin. |
| 5 (+VS) | Positive Supply Rail | Accepts 3 V to 12 V single-ended or ±1.5 V to ±6 V split supplies; PSRR > 54 dB reduces supply noise coupling. |
| 6 (OUT2) | Amplifier 2 Output | Matched performance to OUT1; enables differential signaling or independent channel processing. |
| 7 (–IN2) | Inverting Input, Amp 2 | Electrically isolated from –IN1; supports independent feedback networks for dual-path signal conditioning. |
| 8 (+IN2) | Noninverting Input, Amp 2 | Identical specs to +IN1; allows synchronous biasing for differential ADC driver topologies. |
Key Features
| Feature | Design Value |
|---|---|
| 325 MHz bandwidth at G = +1 | Enables full-spectrum NTSC/PAL video amplification (0–5.5 MHz) with >50× margin for filter roll-off and PCB losses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8058ARZ | Same silicon, SOIC-8 package (5.0 mm × 4.0 mm); θJA = 160°C/W vs. 200°C/W for MSOP. | Better thermal margin in high-power-density layouts; larger footprint limits use in ultra-compact imaging modules. | Select AD8058ARZ when board space permits and thermal headroom is constrained by adjacent components. |
| LMH6629MA/NOPB | Higher 1.5 GHz bandwidth but 12.5 mA/amplifier supply current; 10.5 nV/√Hz noise; SOIC-8 only. | Overqualified for NTSC video but suitable for >100 MSPS ADC drivers where bandwidth >500 MHz is required. | Choose LMH6629MA/NOPB only when >1 GHz small-signal bandwidth is mandatory and power budget allows +100% quiescent current increase. |
Compared with AD8058ARMZ, AD8058ARZ offers identical electrical performance in a thermally superior but larger SOIC package, while LMH6629MA/NOPB trades higher noise and power for extreme bandwidth-making AD8058ARMZ optimal for cost-sensitive, space-constrained video and imaging designs requiring balanced speed, linearity, and efficiency.

FAQ
What is the maximum capacitive load the AD8058ARMZ can drive without external compensation?
The AD8058ARMZ can drive up to 30 pF capacitive load with ≤30% overshoot under unity-gain conditions, as specified in the Absolute Maximum Ratings table. This capability enables direct interface with ADC input capacitance (typically 5–15 pF) and short coaxial traces without adding series isolation resistors-simplifying layout and preserving transient response integrity in the AD8058ARMZ-based design.
Does the AD8058ARMZ support single-supply operation?
Yes, the AD8058ARMZ operates from a single 3 V to 12 V supply, with input common-mode voltage range specified from 0.9 V to 3.4 V at 5 V supply. Its rail-to-rail output swing (1.2 V to 3.4 V into 150 Ω) and internal level-shifting architecture allow robust single-supply use in video buffering and sensor signal conditioning-provided the input signal remains within the validated common-mode window for the AD8058ARMZ.
What is the guaranteed operating temperature range for the AD8058ARMZ?
The AD8058ARMZ is rated for industrial operation from −40°C to +85°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings tables. All key specifications-including bandwidth, distortion, and output swing-are guaranteed across this full range, making the AD8058ARMZ suitable for embedded vision systems deployed in automotive cabins, factory automation, and outdoor surveillance equipment.
How does the AD8058ARMZ compare to the AD8057 in terms of pin compatibility and performance?
The AD8058ARMZ is not pin-compatible with the AD8057: the AD8057 is a single amplifier offered in SOIC-8 or SOT-23-5 packages, while the AD8058ARMZ is a dual amplifier in MSOP-8. Electrically, both share identical per-amplifier specs (325 MHz bandwidth, 7 nV/√Hz noise), but the AD8058ARMZ adds channel-to-channel crosstalk control (−60 dB at 5 MHz) and matched AC performance essential for differential signaling-key differentiators in the AD8058ARMZ's dual-channel architecture.
Is the AD8058ARMZ RoHS compliant?
Yes, the AD8058ARMZ is RoHS compliant, as indicated by the "Z" suffix in its ordering code per Analog Devices' Ordering Guide. The device meets EU Directive 2011/65/EU requirements, with lead-free terminations and halogen-free molding compound-verified through material declarations and third-party testing applicable to the AD8058ARMZ manufacturing lot.
