Product details

The AD8091ARZ is a single-channel voltage-feedback amplifier from Analog Devices built for signal chains that need to preserve fast edges and wide frequency content. Its 110 MHz -3dB bandwidth and 170 V/µs slew rate make it a natural fit for video distribution, ADC drivers, and high-speed data acquisition where settling time and harmonic distortion matter more than DC precision. The rail-to-rail output stage keeps the full dynamic range available even on a 3 V supply, which is useful when the ADC reference or the next-stage input range is close to the rail.

Supply range and operating environment

Input offset voltage is 1.8 mV typical, and input bias current runs 1.4 µA, both reasonable for a high-speed amp where the signal is AC-coupled or the source impedance is low.

Package and footprint

Supply current is 4.8 mA per amplifier, which keeps the thermal rise low in the SOIC package even at full output swing.

Lifecycle and sourcing

ADI lists the AD8091ARZ as Active with a ROHS3 compliance status.

Frequently asked questions

Can the AD8091ARZ operate at 3.3 V?

Yes, the 3 V minimum supply means a 3.3 V rail is within spec. The rail-to-rail output gives you the full swing at that low voltage.

What are the alternatives to AD8091ARZ?

The choice depends on whether you need the extra bandwidth and temperature range or the lower power consumption.
