The AD8061 is the single-channel member of Analog Devices' AD8061/AD8062/AD8063 family of low-cost, high-speed voltage-feedback amplifiers. Where a current-feedback part chases raw gigahertz bandwidth, the AD8061 targets the larger volume problem: a fast, well-behaved amplifier with a rail-to-rail output that runs from a single low-voltage supply and costs little. AD8061ARTZ-REEL7 is the RoHS-compliant ("Z") SOT-23-5 version on 7-inch tape and reel.

Two traits define it. First, the rail-to-rail output: the output swings to within millivolts of each supply rail, so on a single 5 V rail the signal can use almost the full 0 V to 5 V span instead of losing a volt or more at each end. On a low supply that recovered headroom is the difference between an adequate and a poor dynamic range, which is exactly why rail-to-rail parts dominate single-supply, battery and portable designs. Second, the speed: 300 MHz small-signal bandwidth at unity gain and a 500 V/µs slew rate, with 35 ns settling to 0.1%, are enough for video, fast photodiode signals and driving an ADC.

The AD8061 runs from a single supply of 2.7 V to 8 V or a dual ±1.35 V to ±4 V, drawing about 6.8 mA per amplifier. Note that while the output is rail-to-rail, the input common-mode range is not (roughly -0.2 V to +3.2 V on a 3 V supply), so the part is usually applied in non-inverting gain or as an output/ADC driver rather than with inputs sitting at the top rail. The 5-lead SOT-23 keeps it small enough for handheld and dense boards.

Note: Values are taken from the Analog Devices AD8061 datasheet. Confirm every parameter against the latest official documentation before committing a design.

AD8061ARTZ-REEL7 is supplied in the 5-lead SOT-23 (ADI outline RT-5), the small 3-pin-per-side surface-mount body about 2.9 mm x 1.6 mm. "Z" marks the RoHS-compliant lead-free finish and "REEL7" the 7-inch tape-and-reel packing. The same AD8061 die is also offered in 8-lead SOIC (R-8) and µSOIC-8 (RM-8); the SOT-23-5 is the smallest, chosen for handheld and space-constrained boards. Keep the supply pins decoupled close to the package to hold the 300 MHz bandwidth. Package dimensions and pin-1 orientation are shown below.

📄 Full specifications are detailed in the official Analog Devices AD8061 datasheet.

The 5-lead SOT-23 brings out a single amplifier with separate supply pins:

• Pin 1 - VOUT: Amplifier output, rail-to-rail.
• Pin 2 - -VS: Negative supply (or ground in single-supply use); decouple close to the pin.
• Pin 3 - +IN: Non-inverting input.
• Pin 4 - -IN: Inverting input.
• Pin 5 - +VS: Positive supply (2.7 V to 8 V single, or +rail); decouple close to the pin.

Refer to the package drawing below for the physical pin numbering of the SOT-23-5.

Selection Tips: Stay with the AD8061 single for a low-cost 300 MHz rail-to-rail-output stage on a single supply. Step to the dual AD8062 (or AD8052) when two matched channels are needed, AD8063 when a disable pin matters, or AD8065 when the source impedance is high and a FET input helps. For 1 GHz-class current-feedback speed instead, see the AD8009.

Analog Devices, Inc. (ADI), headquartered in Wilmington, Massachusetts, USA, is a global leader in high-performance analog, mixed-signal and RF semiconductors, and the long-standing reference name in high-speed amplifiers. The AD8061 sits in ADI's value high-speed amplifier line, where rail-to-rail output and single-supply operation are paired with low cost for high-volume signal-chain designs.

ADI backs the AD8061 with full datasheet characterization, SPICE models, evaluation support and long-term availability, and the shared AD8061/8062/8063 family lets a design scale from one to two channels or add a disable pin without changing the basic circuit.
