Product details
Overview
AD8692ARZ-REEL from Analog Devices is a dual, rail-to-rail output, CMOS operational amplifier optimized for low-noise, low-distortion signal conditioning in single-supply systems. It delivers 10 MHz gain bandwidth, 8 nV/√Hz voltage noise density at 1 kHz, and 0.0006% THD+N at 1 kHz - enabling precision photodiode amplification and battery-powered medical instrumentation.
For engineers reviewing the AD8692ARZ-REEL datasheet, AD8692ARZ-REEL pinout, AD8692ARZ-REEL application, or AD8692ARZ-REEL equivalent, key selection criteria include its 400 µV typical offset voltage, 6 µV/°C max drift over −40°C to +125°C, 0.95 mA supply current per amplifier, rail-to-rail output swing, and qualification for automotive-grade operation.
Technical Context
The AD8692ARZ-REEL employs a CMOS input stage delivering 1 pA maximum input bias current and 5 pF common-mode input capacitance, supporting high-impedance sensor interfaces without loading. Its unity-gain stable architecture achieves 65° phase margin with 10 MHz GBP and 5 V/µs slew rate under 2 kΩ load conditions.
Designed for single-supply operation from 2.7 V to 6 V, it maintains rail-to-rail output drive capability (25 mV VOL / 4.96 V VOH at 1 mA, VS = 5 V) across the full industrial temperature range. The device meets automotive AEC-Q100 stress test requirements and operates reliably from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 10 MHz - supports stable closed-loop operation up to 10× gain at 1 MHz or unity gain at 10 MHz. |
| Input Offset Voltage | 0.4 mV typical - enables accurate DC-coupled amplification of µV-level sensor signals without nulling circuitry. |
| Offset Voltage Drift | 6 µV/°C max - ensures <±0.6 mV total offset shift over full −40°C to +125°C operating range. |
| Voltage Noise Density | 8 nV/√Hz at 1 kHz - critical for preserving SNR in photodiode and precision instrumentation front-ends. |
| Supply Current per Amplifier | 0.95 mA typical at 25°C - balances speed and power efficiency for portable and loop-powered devices. |
| Output Voltage Swing | Rail-to-rail - delivers full 0.025 V to 4.975 V swing at 1 mA load on 5 V supply, maximizing dynamic range. |
| Total Harmonic Distortion + Noise | 0.0006% at 1 kHz - preserves audio and AC signal fidelity in portable audio and filter applications. |
Pinout & Package
AD8692ARZ-REEL is housed in an 8-lead narrow SOIC (R-8) surface-mount package, 3.9 mm × 4.9 mm footprint, 1.75 mm height, JEDEC MS-012-AA compliant.

| 3 | +IN A | Non-inverting input of Amplifier A - differential pair input with 5 pF CCM, 2.5 pF CDM. |
| 4 | V– | Negative supply rail - connects to ground in single-supply configurations; supports true rail-to-rail input down to −0.3 V. |
| 5 | V+ | Positive supply rail - accepts 2.7 V to 6 V; PSRR of 95 dB minimizes supply ripple coupling. |
| 6 | –IN B | Inverting input of Amplifier B - electrically isolated from Amplifier A; channel separation >140 dB at 1 kHz. |
| 7 | OUT B | Amplifier B output - independently buffered; identical AC/DC performance to OUT A. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. AD8692ARZ-REEL's 6 µV/°C; higher 17 µV p-p 0.1–10 Hz noise. | Better long-term DC stability but higher low-frequency noise; less suitable for wideband photodiode amps. | Choose OPA2333AIDR when microvolt-level DC accuracy dominates over wideband noise performance. |
| LMV722MMX/NOPB | Lower cost; 1.25 mA supply current; 1.2 MHz GBP; 25 nV/√Hz noise - significantly slower and noisier than AD8692ARZ-REEL. | Acceptable for non-critical DC amplification but inadequate for precision AC signal chains or medical-grade filtering. | Choose LMV722MMX/NOPB only for cost-sensitive, low-speed applications where 10 MHz bandwidth and 8 nV/√Hz noise are unnecessary. |
Compared with OPA2333AIDR and LMV722MMX/NOPB, AD8692ARZ-REEL uniquely balances 10 MHz bandwidth, 8 nV/√Hz noise, and 6 µV/°C drift in a dual configuration - making it optimal for battery-powered medical and optical sensing where both speed and precision matter.

FAQ
What is the operating temperature range for AD8692ARZ-REEL?
AD8692ARZ-REEL is specified for continuous operation from −40°C to +125°C across all electrical parameters. This extended industrial temperature range is validated per AEC-Q100 stress testing, making AD8692ARZ-REEL suitable for under-hood automotive electronics and industrial control systems where thermal robustness is critical.
Does AD8692ARZ-REEL support true rail-to-rail input?
AD8692ARZ-REEL features rail-to-rail *output* but not rail-to-rail *input*. Its input common-mode voltage range extends to −0.3 V below V– and +3.9 V above V– at VS = 5 V, allowing operation within 300 mV of the negative rail but not to the positive rail. For true rail-to-rail input, consider the AD8605 series instead of AD8692ARZ-REEL.
What is the maximum capacitive load AD8692ARZ-REEL can drive stably?
AD8692ARZ-REEL remains unity-gain stable with up to 200 pF capacitive load, as verified in Figure 19 and Figure 20 of the Rev. F datasheet. Driving larger loads requires external isolation resistance (e.g., 10–100 Ω in series with the output) to maintain phase margin above 60° and prevent peaking or oscillation.
Is AD8692ARZ-REEL pin-compatible with other dual op-amps in SOIC-8?
No, AD8692ARZ-REEL uses a standard 8-lead SOIC_N (R-8) package with industry-standard pinout (OUT A, –IN A, +IN A, V–, V+, –IN B, OUT B, +IN B), but functional compatibility depends on electrical specs. It is not a drop-in replacement for legacy parts like LM358 due to differences in input stage (CMOS vs. bipolar), supply range, and output drive - always verify biasing and loop stability when substituting AD8692ARZ-REEL.
What packaging and reel options are available for AD8692ARZ-REEL?
AD8692ARZ-REEL is supplied in tape-and-reel format per JEDEC standard, with 2,500 units per reel. The "REEL" suffix denotes this packaging; the base part AD8692ARZ is available in tube format. Both share identical R-8 SOIC package dimensions (4.90 mm × 3.90 mm × 1.75 mm) and electrical specifications.
