- Part Models
- 3
- 1ku List Price
- Starting From $0.90
Part Details
- Low cost single (AD8091) and dual (AD8092) amplifiers
- Fully specified at +3 V, +5 V, and ±5 V supplies
- Single-supply operation
Output swings to within 25 mV of either rail - High speed and fast settling on 5 V
110 MHz, −3 dB bandwidth (G = +1)
145 V/μs slew rate
50 ns settling time to 0.1% - Low power of 4.4 mA per amplifier
- Good video specifications (G = +2)
Gain flatness of 0.1 dB to 20 MHz; RL = 150 Ω
0.03% differential gain error; RL = 1 kΩ
0.03%differential phase error; RL = 1 kΩ - Low distortion
−80 dBc total harmonic @ 1 MHz; RL = 100 Ω - Outstanding load drive capability
Drives 45 mA, 0.5 V from supply rails
Drives 50 pF capacitive load (G = +1)
The AD8091 (single) and AD8092 (dual) are low cost, voltage feedback, high speed amplifiers designed to operate on +3 V, +5 V, or ±5 V supplies. The AD8091 / AD8092 have true single-supply capability, with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail.
Despite their low cost, the AD8091 / AD8092 provide excellent overall performance and versatility. The output voltage swing extends to within 25 mV of each rail, providing the maximum output dynamic range with excellent overdrive recovery. This makes the AD8091/AD8092 useful for video electronics, such as cameras, video switchers, or any high speed portable equipment. Low distortion and fast settling make them ideal for active filter applications. The AD8091 / AD8092 offer a low power supply current and can operate on a single 3 V power supply. These features are ideally suited for portable and battery-powered applications where size and power are critical.
The wide bandwidth and fast slew rate make these amplifiers useful in many general-purpose, high speed applications where dual power supplies of up to ±6 V and single supplies from +3 V to +12 V are needed.
This low cost performance is offered in an 8-lead SOIC (AD8091 / AD8092), a tiny SOT23-5 (AD8091), and an MSOP (AD8092).

Tools & Simulations
LTspice 1
Models for the following parts are available in LTspice:
- AD8091
Signal Chain Designer - BETA
Signal Chain Designer is a web-based tool designed to create and simulate complex precision signal chains. See your circuit’s performance before you commit to your PCB: transfer function, noise, power consumption, input range, and DC error. Quickly experiment with different parts and architectures. Signal chains can be exported to LTspice for further analysis.
Open ToolPower Dissipation vs Die Temp
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
Open ToolAnalog Filter Wizard
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Open ToolAnalog Photodiode Wizard
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
