Analog Devices Inc. AD8091ART-REEL

Overview

AD8091ART-REEL from Analog Devices is a single, rail-to-rail output voltage-feedback operational amplifier optimized for high-speed, low-power, single-supply operation. It delivers 110 MHz −3 dB bandwidth (G = +1), 145 V/μs slew rate, and 25 mV rail-to-rail output swing at 5 V supply - enabling precision video line driving, active filtering, and clock buffering in portable and industrial systems.

For engineers reviewing the AD8091ART-REEL datasheet, AD8091ART-REEL pinout, AD8091ART-REEL application, or AD8091ART-REEL equivalent, key selection criteria include its SOT23-5 package compatibility, 4.4 mA quiescent current, 50 ns settling time to 0.1%, and verified performance across +3 V, +5 V, and ±5 V supplies - critical for battery-powered imaging, CCD interfaces, and composite video signal conditioning.

Technical Context

The AD8091ART-REEL employs a voltage-feedback architecture with fully differential input stage and Class AB output stage, supporting true single-supply operation down to +3 V. Its input common-mode range extends 200 mV below the negative rail and within 1 V of the positive rail, while output swing reaches within 25 mV of both rails under 2 kΩ load.

Designed for stability with capacitive loads up to 50 pF (G = +1), it features low input capacitance (1.4 pF) and high open-loop gain (98 dB typ., RL = 2 kΩ), enabling robust active filter implementation and fast overdrive recovery (≤60 ns). Its 16 nV/√Hz input voltage noise and 850 fA/√Hz input current noise support high-fidelity signal conditioning in professional camera and sync stripper circuits.

FAQ

What is the maximum supply voltage for AD8091ART-REEL?

The AD8091ART-REEL supports an absolute maximum supply voltage of 12.6 V, with recommended operating range from +3 V to +12 V (single supply) or ±5 V (dual supply). At +5 V, it achieves 110 MHz bandwidth and 145 V/μs slew rate; operation beyond 12.6 V risks permanent damage per Absolute Maximum Ratings (Table 4).

Does AD8091ART-REEL support rail-to-rail input?

No, AD8091ART-REEL features rail-to-rail *output* only. Its input common-mode voltage range extends 200 mV below −VS and within 1 V of +VS (e.g., −0.2 V to +4.0 V at +5 V supply), but does not reach both rails. For true rail-to-rail input, consider alternatives like ADA4891-1ARJZ-R7.

Can AD8091ART-REEL drive a 75 Ω video load directly?

Yes - AD8091ART-REEL delivers 45 mA output current and sustains 0.2 V to 4.8 V swing into 150 Ω (per Table 1), making it suitable for 75 Ω terminated lines when configured with appropriate gain and termination. Application circuits like the sync stripper (Figure 35) and video line driver confirm direct 75 Ω drive capability in production designs.

What is the thermal resistance (θJA) of the AD8091ART-REEL SOT23-5 package?

The AD8091ART-REEL in SOT23-5 (RJ-5) has a junction-to-ambient thermal resistance (θJA) of 180°C/W on a JEDEC-standard four-layer board (Figure 4). This value assumes standard copper pour and via placement; actual θJA improves with added thermal vias and copper area under the exposed pad (if present) - critical for sustained 45 mA output loading.

Is AD8091ART-REEL suitable for driving ADC inputs in high-speed data acquisition?

Yes - AD8091ART-REEL's 50 ns settling time to 0.1%, 110 MHz bandwidth, and low distortion (−80 dBc THD @ 1 MHz) make it well-suited as an ADC driver for sampling rates up to ~20 MSPS. Its 4.4 mA quiescent current also supports low-power DAQ systems, though layout must minimize input capacitance (<1.4 pF) to avoid peaking per Layout Guidelines (Page 12).
