Product details
Overview
AD8061ARZ-REEL7 from Analog Devices is a single-channel, rail-to-rail output voltage feedback operational amplifier optimized for high-speed, low-power, single-supply applications. It delivers 300 MHz −3 dB bandwidth (G = 1, VS = 5 V), 650 V/µs slew rate, and 8.5 nV/√Hz input voltage noise, enabling precision video buffering, ADC driving, and clock signal conditioning in space-constrained systems.
For engineers reviewing the AD8061ARZ-REEL7 datasheet, AD8061ARZ-REEL7 pinout, AD8061ARZ-REEL7 application, or AD8061ARZ-REEL7 equivalent, key selection criteria include its 2.7 V to 8 V supply range, 35 ns settling time to 0.1%, rail-to-rail output swing (0.1 V to 4.9 V on 5 V supply), and verified performance into 150 Ω loads for NTSC video (0.01% differential gain error).
Technical Context
The AD8061ARZ-REEL7 employs a true single-supply voltage feedback architecture with a high-slew-rate input stage capable of sensing signals down to 200 mV below the negative rail. Its rail-to-rail output stage uses a common-emitter topology that achieves ≤30 mV headroom to either supply under light loads and maintains ≥25 mA drive capability.
It operates across −40°C to +85°C with guaranteed 300 MHz small-signal bandwidth at 5 V supply, 0.1 dB flatness to 30 MHz, and robust overload recovery (35 ns). Input common-mode range extends from −0.2 V to +3.2 V at VS = 5 V, supporting ground-referenced inputs in single-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 300 MHz at G = 1, 5 V supply - supports high-definition video and fast data acquisition without phase distortion. |
| Slew Rate | 650 V/µs - enables faithful reproduction of fast-edged digital clocks and video sync pulses. |
| Settling Time | 35 ns to 0.1% with 2 V step - ensures accurate sampling in high-speed ADC front-ends. |
| Input Voltage Noise | 8.5 nV/√Hz at 100 kHz - preserves SNR in photodiode preamps and sensor interfaces. |
| Output Swing | 0.1 V to 4.9 V (RL = 2 kΩ, VS = 5 V) - maximizes dynamic range in 5 V single-supply systems. |
| Supply Current | 6.8 mA typical - balances speed and power for battery-sensitive portable instrumentation. |
| Differential Gain Error | 0.01% into 150 Ω - meets broadcast-grade NTSC video fidelity requirements. |
Pinout & Package
AD8061ARZ-REEL7 is packaged in an 8-lead SOIC_N (R) surface-mount package with standard pinout and no internal connections on pins 1 and 8. The device requires minimal external components and is optimized for high-frequency stability with proper PCB layout.
| Pin | Circuit Role | Design Meaning |
|---|---|---|

| 2 | −IN | Inverting input terminal; accepts differential or single-ended signals within specified common-mode range. |
| 3 | +IN | Non-inverting input terminal; referenced for gain-setting and biasing in follower or non-inverting configurations. |
| 4 | −VS | Negative supply pin; supports operation down to 2.7 V single supply (−VS = GND). |
| 5 | +VS | Positive supply pin; accepts up to 8 V; decoupling capacitor required near pin for stability. |
| 6 | VOUT | Amplified output node; drives capacitive loads up to 300 pF (with RS = 4.7 Ω) and resistive loads down to 150 Ω. |
| 7 | NC | No internal connection; must be left floating or grounded per layout best practices. |
| 8 | NC | No internal connection; must be left floating or grounded per layout best practices. |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz bandwidth but 15 mA supply current; no rail-to-rail output (clips ~1.2 V from rails). | Better for RF IF amplification; unsuitable for 0–5 V video swing or low-voltage ADC driving. | Select LMH6629MA/NOPB only when >1 GHz bandwidth is mandatory and power/DC swing are secondary. |
| ADA4897-1ARMZ | Lower 225 MHz bandwidth, 1 nV/√Hz noise, 1.2 mA supply current; rail-to-rail output and same SOIC-8 footprint. | Preferred for ultra-low-noise, low-power precision apps (e.g., EEG front-end); insufficient for 30+ MHz video. | Choose ADA4897-1ARMZ when noise <2 nV/√Hz and quiescent current <2 mA are critical, and bandwidth ≤225 MHz suffices. |
Compared with LMH6629MA/NOPB and ADA4897-1ARMZ, AD8061ARZ-REEL7 uniquely balances 300 MHz bandwidth, rail-to-rail output, sub-7 mA power, and video-grade linearity-making it optimal for cost-sensitive, single-supply, high-fidelity analog signal paths where both speed and DC accuracy matter.

FAQ
What is the maximum supply voltage for AD8061ARZ-REEL7?
The absolute maximum supply voltage for AD8061ARZ-REEL7 is 8 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, Analog Devices recommends staying within the recommended operating range of 2.7 V to 8 V, with typical evaluation performed at 5 V and 3 V supplies. The AD8061ARZ-REEL7 maintains 300 MHz bandwidth and 650 V/µs slew rate across this full range.
Does AD8061ARZ-REEL7 support rail-to-rail input operation?
No, AD8061ARZ-REEL7 does not support rail-to-rail input operation. Its input common-mode voltage range is −0.2 V to +3.2 V with VS = 5 V, meaning it can accept signals 200 mV below ground but only up to 1.8 V below the positive rail. This limitation is intentional to preserve high-speed performance and low distortion; exceeding the upper limit degrades bandwidth and increases settling time. The AD8061ARZ-REEL7 is rail-to-rail *output*, not input.
Can AD8061ARZ-REEL7 drive a 150 Ω load for video applications?
Yes, AD8061ARZ-REEL7 is explicitly characterized and qualified to drive 150 Ω loads in video applications. The datasheet specifies differential gain error of 0.01% and differential phase error of 0.04° into 150 Ω at G = 2, meeting NTSC broadcast standards. Output voltage swing is guaranteed to 0.1 V (low) and 4.75 V (high) under these conditions, and the amplifier delivers ≥25 mA continuous output current - sufficient for sustained 1 Vpp video signals across 150 Ω.
What is the thermal resistance (θJA) of the AD8061ARZ-REEL7 SOIC package?
The AD8061ARZ-REEL7 in the 8-lead SOIC_N (R) package has a junction-to-ambient thermal resistance (θJA) of 160°C/W, as documented in the Absolute Maximum Ratings section. This value assumes standard JEDEC 2-layer board conditions. For high-power-density layouts, designers should apply appropriate copper pour and thermal vias to reduce effective θJA and ensure junction temperature remains below 150°C under worst-case ambient and load conditions.
Is AD8061ARZ-REEL7 pin-compatible with other members of the AD806x family?
AD8061ARZ-REEL7 is pin-compatible with AD8062ARZ (dual) in the same 8-lead SOIC package, sharing identical pin 1–8 assignments for +IN, −IN, VOUT, −VS, and +VS. However, it is *not* pin-compatible with AD8063ARZ (which includes a DISABLE pin on pin 5) or with SOT-23 variants (AD8061ART-REEL7). Always verify the specific variant's connection diagram - Figure 1 in the Rev. J datasheet confirms the SOIC pinout for AD8061/AD8063.
