Product details
Overview
AD8061ARZ 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 imaging and portable systems.
For engineers reviewing the AD8061ARZ datasheet, AD8061ARZ pinout, AD8061ARZ application, or AD8061ARZ 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), differential gain error of 0.01% into 150 Ω, and SOIC-8 package compatibility with standard PCB layouts.
Technical Context
The AD8061ARZ 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 achieves ≤30 mV headroom to either supply under light loads and maintains 0.1 V to 4.9 V swing into 2 kΩ at 5 V.
It supports stable operation across 2.7 V to 8 V supplies, exhibits 62 dB SFDR at 5 MHz, and sustains 0.1 dB gain flatness to 30 MHz-critical for NTSC/PAL video and high-fidelity signal chain interfaces where distortion and phase linearity are tightly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 300 MHz at G = 1, 5 V supply - enables wideband video, RF IF, and fast data acquisition signal paths |
| Slew Rate | 650 V/µs - supports clean 1 V step response in <35 ns without overshoot or ringing |
| Input Voltage Noise | 8.5 nV/√Hz at 100 kHz - preserves SNR in photodiode preamps and sensor front-ends |
| Output Swing | 0.1 V to 4.9 V (RL = 2 kΩ, VS = 5 V) - ensures full dynamic range utilization in 3.3 V/5 V logic-coupled systems |
| Differential Gain Error | 0.01% into 150 Ω - meets broadcast-grade video fidelity requirements for RGB and sync stripper circuits |
| Supply Current | 6.8 mA typical - balances speed and power for battery-sensitive handheld and embedded applications |

| 3 | +IN | Non-inverting input - reference point for gain configuration; same CMVR as −IN |
| 4 | −VS | Negative supply rail - connects to ground in single-supply operation; supports −0.2 V input common-mode |
| 5 | +VS | Positive supply rail - accepts 2.7 V to 8 V; powers internal bias and output stage |
| 6 | VOUT | Amplifier output - delivers rail-to-rail swing up to 50 mA load current; drives 150 Ω video loads |
| 7 | NC | No connect - must be left floating; no internal connection or function |
| 8 | NC | No connect - must be left floating; no internal connection or function |
Key Features

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, 1000 V/µs slew rate, but 12.5 mA supply current and no rail-to-rail output | Better for ultra-wideband IF amplification; unsuitable for rail-to-rail output or low-voltage (<3 V) operation | Select when bandwidth >500 MHz is required and output swing beyond 1.5 V is acceptable |
| ADA4891-1ARJZ-R7 | Lower 225 MHz bandwidth, 110 V/µs slew rate, but 1.2 mA supply current and rail-to-rail I/O | Better for ultra-low-power portable designs; insufficient for 30 MHz video flatness or fast settling | Select when power budget <2 mA dominates and 30 MHz bandwidth suffices |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, AD8061ARZ uniquely balances 300 MHz bandwidth, rail-to-rail output, 6.8 mA power, and 0.01% video linearity - making it optimal for cost-sensitive, performance-critical video and ADC driver roles where both speed and supply flexibility matter.

FAQ
What is the maximum supply voltage for AD8061ARZ?
The AD8061ARZ supports an absolute maximum supply voltage of 8 V across +VS and −VS pins. Operation is specified from 2.7 V to 8 V, with full performance validated at 3 V, 5 V, and ±2.5 V supplies. Exceeding 8 V risks permanent damage per Absolute Maximum Ratings Table 4.
Does AD8061ARZ support rail-to-rail input?
No, AD8061ARZ does not support rail-to-rail input. Its input common-mode voltage range is −0.2 V to +3.2 V at VS = 5 V - extending 200 mV below −VS but only to within 1.8 V of +VS. Input signals must remain within this window to maintain specified offset, bandwidth, and distortion performance.
Can AD8061ARZ drive a 150 Ω video load with 0.1 dB flatness?
Yes, AD8061ARZ achieves 0.1 dB gain flatness to 30 MHz into a 150 Ω load at G = 2, as confirmed in the Applications section and Figure 23 of the Rev. J datasheet. This meets broadcast video requirements for RGB, Y/C, and sync stripper circuits without external equalization.
What is the thermal resistance (θJA) of AD8061ARZ in SOIC-8 package?
The AD8061ARZ in 8-lead SOIC_N (R) package has a junction-to-ambient thermal resistance (θJA) of 160°C/W, as specified in the Absolute Maximum Ratings section. This value assumes standard 2-layer PCB layout with no copper pour; actual θJA improves with enhanced heatsinking.
Is AD8061ARZ pin-compatible with AD8062ARZ or AD8063ARZ?
No, AD8061ARZ is not pin-compatible with AD8062ARZ (dual) or AD8063ARZ (single with disable). While all share the same SOIC-8 footprint, AD8062ARZ uses Pins 1, 7, and 8 for second amplifier functions, and AD8063ARZ repurposes Pin 5 as DISABLE - making direct substitution impossible without PCB redesign.
