Product details
Overview
AD8061AR-REEL from Analog Devices is a single-channel, rail-to-rail output voltage feedback operational amplifier optimized for high-speed, low-power, single-supply operation. It delivers 300 MHz −3 dB bandwidth (G = 1, VS = 3 V), 650 V/µs slew rate, and 6.8 mA quiescent current per amplifier, enabling use in video amplification, ADC driving, and clock buffering where signal fidelity and fast settling (35 ns to 0.1%) are critical.
For engineers reviewing the AD8061AR-REEL datasheet, AD8061AR-REEL pinout, AD8061AR-REEL application, or AD8061AR-REEL equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOIC-8 pin mapping, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The AD8061AR-REEL employs a voltage-feedback architecture with a high-slew-rate input stage capable of sensing signals down to 200 mV below the negative rail and up to 1.8 V below the positive rail (VS = 5 V). Its rail-to-rail output stage achieves ≤300 mV swing from either supply under 2 kΩ load, supporting true single-supply operation from 2.7 V to 8 V.
It maintains stable performance across supply voltages: bandwidth drops only to 300 MHz at VS = 3 V and 230 MHz at VS = 2.7 V, while THD remains −60 dBc at 5 MHz and differential gain/phase errors hold at 0.01% and 0.04° into 150 Ω - meeting broadcast-grade video requirements without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 300 MHz at G = 1, VS = 3 V - supports full HD baseband video (up to ~30 MHz) with >10× margin and preserves edge integrity in fast digital timing paths. |
| Slew Rate | 650 V/µs at G = 1, RL = 2 kΩ - enables clean 1 V step response in <35 ns, critical for driving SAR ADC inputs without distortion-induced code errors. |
| Input Offset Voltage | 6 mV max - ensures ≤0.6% gain error in unity-gain buffer configurations used in precision sensor signal chains. |
| Supply Current | 6.8 mA typical per amplifier - allows integration into power-constrained portable imaging systems without thermal derating concerns. |
| Output Swing | 0.1 V to 4.86 V (RL = 2 kΩ, VS = 5 V) - delivers true rail-to-rail dynamic range for 12-bit ADCs operating on 5 V supplies, maximizing SNR utilization. |
| Input Noise | 8.5 nV/√Hz at 100 kHz - limits added noise to <1 LSB in 12-bit, 1 MSPS data acquisition systems with 1 kΩ source impedance. |
| Settling Time | 35 ns to 0.1% with 2 V step - meets timing budget for multiplexed analog front-ends switching between channels at >10 MHz rates. |
Pinout & Package
AD8061AR-REEL is packaged in an 8-lead SOIC (R) with standard pinout and no internal connections on pins 1 and 8. Pin assignments are validated per Analog Devices Rev. J datasheet Figure 1 and Table of Contents "Connection Diagrams" section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection; must be left floating or grounded per layout best practices to avoid parasitic coupling. |
| 2 | –IN | Inverting input node; requires matched trace length and impedance control when used in high-frequency closed-loop configurations to minimize phase mismatch. |
| 3 | +IN | Non-inverting input node; accepts common-mode voltage from −0.2 V to +3.2 V (VS = 5 V), enabling direct interface with CMOS logic or photodiode bias networks. |
| 4 | –VS | Negative supply terminal; must be decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin to suppress high-frequency PSRR degradation. |
| 5 | +VS | Positive supply terminal; supports 2.7 V to 8 V operation; 5 V nominal enables compatibility with USB-powered and industrial 5 V rails. |
| 6 | VOUT | Amplifier output; drives capacitive loads up to 300 pF (G = 2, RS = 4.7 Ω) - sufficient for direct connection to coaxial cables or ADC input filters without isolation buffers. |
| 7 | NC | No internal connection; same as Pin 1 - no routing or termination required. |
| 8 | NC | No internal connection; confirmed unconnected per datasheet Figure 1 and "NC = NO CONNECT" annotation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 0.1 V of both rails under 2 kΩ load - eliminates need for dual supplies in battery-powered video preamps and simplifies level-shifting for 3.3 V microcontroller interfaces. |
| 300 MHz bandwidth at 3 V supply | Maintains high-frequency response down to low-voltage operation - enables compact, single-cell Li-ion powered test equipment without sacrificing signal bandwidth. |
| 35 ns settling to 0.1% | Ensures accurate sampling of fast transient events in oscilloscope front-ends and time-of-flight sensor receivers without post-acquisition correction. |
| 0.01% differential gain error | Preserves color fidelity in NTSC/PAL composite video paths - meets broadcast specification without external calibration or feedback trimming. |
| 6.8 mA quiescent current | Reduces thermal load in densely packed multi-channel instrumentation modules - supports 16-channel designs within 1 W total dissipation budget. |

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 GBW but 13.5 mA supply current; no rail-to-rail output (clips 1.2 V from rails). | Better for RF IF amplification; unsuitable for single-supply rail-to-rail output stages. | Select LMH6629MA/NOPB only when bandwidth >1 GHz is mandatory and supply headroom permits non-rail output swing. |
| ADA4897-1ARZ-R7 | Lower 220 MHz bandwidth but superior 0.9 nV/√Hz noise and 1.2 mA supply current; rail-to-rail output. | Better for low-noise sensor preamps; insufficient for >25 MHz video or fast ADC driving. | Choose ADA4897-1ARZ-R7 when system noise floor dominates over speed, e.g., precision thermopile or strain gauge signal conditioning. |
Compared with LMH6629MA/NOPB and ADA4897-1ARZ-R7, AD8061AR-REEL uniquely balances 300 MHz bandwidth, rail-to-rail output, and 6.8 mA power in a cost-optimized SOIC-8 package - making it the optimal choice for mid-speed video, portable imaging, and general-purpose high-fidelity analog signal routing where both speed and supply flexibility are required.

FAQ
What is the maximum supply voltage for AD8061AR-REEL?
The AD8061AR-REEL has an absolute maximum supply voltage rating of 8 V, as specified in Table 4 of the Rev. J datasheet. Continuous operation above this voltage risks permanent damage. For reliable long-term use, Analog Devices recommends staying within the operational range of 2.7 V to 8 V, with typical evaluation performed at 3 V, 5 V, and ±2.5 V supplies. The AD8061AR-REEL maintains full 300 MHz bandwidth at 3 V and retains usable performance down to 2.7 V.
Does AD8061AR-REEL support rail-to-rail input operation?
No, AD8061AR-REEL does not support rail-to-rail input operation. Its input common-mode voltage range is specified as −0.2 V to +3.2 V with VS = 5 V, meaning it operates 200 mV below the negative rail and up to 1.8 V below the positive rail. This allows true single-supply use but requires input signals to remain within those bounds to maintain specified AC and DC performance. Exceeding the upper limit degrades bandwidth and increases distortion, as shown in Figures 45–47 of the datasheet.
Can AD8061AR-REEL drive a 150 Ω video load with broadcast-grade performance?
Yes, AD8061AR-REEL is explicitly characterized for 150 Ω loads in video applications. At G = 2 and RL = 150 Ω, it achieves 0.01% differential gain error and 0.04° differential phase error - meeting SMPTE and ITU-R BT.601 broadcast specifications. Its 0.1 dB gain flatness extends to 30 MHz and overload recovery is completed within 35 ns, making it suitable for RGB, YPbPr, and composite video signal distribution without external compensation.
What is the thermal performance of AD8061AR-REEL in SOIC-8 package?
In its 8-lead SOIC_N package, AD8061AR-REEL has a junction-to-ambient thermal resistance (θJA) of 160°C/W and junction-to-case (θJC) of 56°C/W. With a maximum power dissipation of 0.8 W (Table 4), its junction temperature rise at 6.8 mA quiescent current and 5 V supply is approximately 22°C above ambient - well within the −40°C to +85°C operating range. Derating curves in Figure 6 confirm safe operation up to +85°C ambient at full load, provided PCB copper area meets minimum layout guidelines.
Is AD8061AR-REEL pin-compatible with other members of the AD806x family?
AD8061AR-REEL (single, no disable) shares the same 8-lead SOIC pinout as AD8062 (dual) and AD8063 (single with disable), but pin functions differ: AD8062 uses Pins 1/8 for second amplifier I/O, and AD8063 repurposes Pin 5 as DISABLE. Therefore, AD8061AR-REEL is not pin-compatible with AD8062 or AD8063 in SOIC-8 form. However, all three share identical Pin 2 (–IN), Pin 3 (+IN), Pin 4 (–VS), Pin 5 (+VS), and Pin 6 (VOUT) assignments - enabling reuse of core amplifier circuitry in layout when migrating between variants.
