Product details
Overview
AD8032ARZ-REEL from Analog Devices is a dual, rail-to-rail input/output voltage feedback operational amplifier optimized for high-speed, low-power applications. It delivers 80 MHz −3 dB bandwidth (G = +1), 30 V/μs slew rate, and 125 ns settling time to 0.1%, operating from a single 2.7 V supply with only 800 μA per amplifier quiescent current. It serves as an A/D converter buffer or active filter stage in portable test instruments and battery-powered systems.
For engineers reviewing the AD8032ARZ-REEL datasheet, AD8032ARZ-REEL pinout, AD8032ARZ-REEL application, or AD8032ARZ-REEL equivalent, key selection criteria include rail-to-rail I/O swing within 20 mV of rails, ±3.4 V differential input voltage rating, −62 dBc THD at 1 MHz, 15 mA output drive, and SOIC_N-8 package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The AD8032ARZ-REEL employs a dual-channel voltage feedback architecture fabricated on Analog Devices' eXtra Fast Complementary Bipolar (XFCB) process. Its input stage dynamically switches between PNP and NPN differential pairs to extend common-mode range beyond rails by 200 mV and prevent phase reversal up to 500 mV beyond supplies.
The rail-to-rail output stage uses common-emitter transistors with ~25 Ω effective collector resistance, enabling 20 mV output swing to rails under light load (10 kΩ), degrading linearly with load current. Open-loop gain remains stable within 250 mV of VS+ and 150 mV of VS−, then declines as output transistors saturate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 80 MHz at G = +1 - supports high-fidelity signal conditioning up to video and IF frequencies |
| Slew Rate | 30 V/μs - enables clean amplification of fast transient signals without slewing distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4807-2ARMZ | Lower 1 nV/√Hz voltage noise, higher 180 MHz bandwidth, but 1.5 mA per amplifier supply current | Better suited for precision low-noise applications where power budget allows >2× current draw | Select ADA4807-2ARMZ when THD < −80 dBc or noise-limited SNR dominates design; avoid if battery life is critical |
| OPA2350UA | Similar 38 MHz bandwidth and 800 μA supply current, but limited 5.5 V max supply and no −40°C to +85°C rating | Restricted to commercial-temperature consumer electronics with lower voltage rails | Choose OPA2350UA only for cost-sensitive, non-industrial designs operating ≤5.5 V and above 0°C |
Compared with ADA4807-2ARMZ and OPA2350UA, AD8032ARZ-REEL uniquely balances 80 MHz bandwidth, rail-to-rail I/O, 800 μA quiescent current, and industrial temperature rating in SOIC_N-8 - making it optimal for portable instrumentation where power, performance, and ruggedness intersect.

FAQ
What supply voltage range does the AD8032ARZ-REEL support?
The AD8032ARZ-REEL operates from a single 2.7 V to 12 V supply or dual ±1.35 V to ±6 V supplies. At 2.7 V, it maintains 80 MHz bandwidth and 30 V/μs slew rate while drawing only 800 μA per amplifier - enabling direct integration with Li-ion, Li-polymer, or triple-AA battery systems without regulation overhead. Full specifications are guaranteed across this range.
Does the AD8032ARZ-REEL require external compensation for unity-gain stability?
No, the AD8032ARZ-REEL is internally compensated for unity-gain stability. It achieves stable operation with ≥45° phase margin at G = +1 across all supply voltages and load conditions up to 15 pF capacitive load. No external compensation components are needed for standard voltage-follower or inverting amplifier configurations.
Can the AD8032ARZ-REEL drive heavy capacitive loads like ADC input capacitors?
The AD8032ARZ-REEL drives up to 15 pF capacitive load while maintaining stability and specified settling time (125 ns to 0.1%). For larger ADC input capacitances (e.g., >20 pF), a small series resistor (10–50 Ω) between AD8032ARZ-REEL output and ADC input is recommended to isolate the capacitor and preserve step response fidelity.
What is the maximum differential input voltage the AD8032ARZ-REEL can tolerate?
The AD8032ARZ-REEL has an absolute maximum differential input voltage rating of ±3.4 V. Exceeding this risks permanent damage to the input transistors. For applications with potential overvoltage transients (e.g., sensor disconnect events), external clamping diodes to the supply rails are advised - especially when operating near the 12.6 V absolute maximum supply rating.
How does rail-to-rail output swing behave under 1 kΩ load for the AD8032ARZ-REEL?
Under 1 kΩ load on a +5 V supply, the AD8032ARZ-REEL output swings from 0.1 V to 4.9 V - i.e., within 100 mV of each rail. This is consistent with its 15 mA output drive specification and 25 Ω effective output transistor resistance. Performance is verified across −40°C to +85°C and documented in Figure 40 of the Rev. G datasheet.
