Product details
Overview
AD8692ARZ-REEL7 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-REEL7 datasheet, AD8692ARZ-REEL7 pinout, AD8692ARZ-REEL7 application, or AD8692ARZ-REEL7 equivalent, key selection criteria include its 6 µV/°C max offset drift over −40°C to +125°C, 0.95 mA/amplifier supply current at 5 V, and guaranteed rail-to-rail output swing into 2 kΩ loads - critical for portable audio and sensor front-end designs requiring stable DC accuracy and wide dynamic range.
Technical Context
The AD8692ARZ-REEL7 employs a CMOS input stage delivering 1 pA max input bias current and 5 pF common-mode input capacitance, enabling high-impedance sensor interfacing without significant loading error. Its unity-gain-stable architecture supports stable operation with capacitive loads up to 200 pF and provides 65° phase margin at 5 V supply.
Designed for extended industrial temperature operation (−40°C to +125°C), it features internal ESD protection per JEDEC JS-001 (±2 kV HBM), rail-to-rail output swing within 20 mV of each rail at 1 mA load, and PSRR of 95 dB at DC - making it suitable for loop-powered transmitters and automotive-grade signal chains where supply rejection and thermal stability are essential.
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 | 0.4–2.0 mV typical - ensures ≤2 mV DC error in precision DC-coupled gain stages. |
| Offset Voltage Drift | 1.3–6 µV/°C max - limits drift-induced error to <0.75 mV over full −40°C to +125°C range. |
| Supply Current/Amplifier | 0.95 mA typical at 5 V - enables dual-channel amplification in sub-2 mA total system power budgets. |
| Output Voltage Swing | Within 20–40 mV of rails at 1 mA - delivers >4.9 Vpp output on 5 V supply for maximum dynamic range. |
| Total Harmonic Distortion + Noise | 0.0006% at 1 kHz - preserves signal fidelity in audio and precision measurement paths. |
| Voltage Noise Density | 8 nV/√Hz at 1 kHz - minimizes contribution to system noise floor in low-level sensor amplifiers. |
Pinout & Package
AD8692ARZ-REEL7 is housed in an 8-lead narrow-body SOIC (R-8) package, compliant with JEDEC MS-012-AA, measuring 4.90 mm × 3.90 mm × 1.75 mm with 1.27 mm lead pitch. The package supports standard reflow profiles and offers θJA = 158°C/W for thermal management in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Delivers rail-to-rail sourced/sunk output current; requires local decoupling if driving capacitive loads >100 pF. |
| 2 - –IN A | Inverting input A | High-impedance CMOS node; sensitive to layout parasitics - keep trace short and guard with ground. |
| 3 - +IN A | Non-inverting input A | High-impedance CMOS node; matches –IN A for balanced input bias current cancellation. |
| 4 - V– | Negative supply rail | Connects to ground or negative rail; serves as reference for both amplifiers' output stage and bias circuitry. |
| 5 - V+ | Positive supply rail | Accepts 2.7–6 V; PSRR of 95 dB suppresses supply ripple from affecting output accuracy. |
| 6 - +IN B | Non-inverting input B | Independent high-Z input for second channel; electrically isolated from Channel A except via shared V+ and V–. |
| 7 - OUT B | Amplifier B output | Independent rail-to-rail output; channel separation >130 dB at 1 kHz prevents crosstalk in dual-path designs. |
| 8 - –IN B | Inverting input B | Matches Pin 2 characteristics; enables matched dual-channel configurations without inter-channel mismatch penalties. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 20 mV of V+ and V– at 1 mA load - maximizes usable output voltage range in single-supply systems. |
| Low input bias current | ≤1 pA max - eliminates significant voltage error across high-value feedback or sensor resistors (>1 MΩ). |
| Low noise performance | 8 nV/√Hz voltage noise density at 1 kHz - maintains SNR in photodiode and strain gauge amplifiers. |
| Automotive qualification option | AD8692WARMZ variants available - meet AEC-Q100 Grade 2 requirements for under-hood and infotainment applications. |
| Extended temperature range | Specified from −40°C to +125°C - enables deployment in industrial motor controls and outdoor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Lower offset (10 µV max) but higher supply current (17 µA typ per amp); chopper-stabilized architecture introduces 1/f noise and switching artifacts. | Better for ultra-low-offset DC applications (e.g., precision weigh scales); unsuitable for audio due to chopper noise. | Select AD8692ARZ-REEL7 when low broadband noise, low distortion, and absence of switching artifacts are required - especially in AC-coupled sensor and audio paths. |
| MCP6V82-E/SN | Zero-drift architecture with 0.5 µV max offset and 0.01 µV/°C drift; higher quiescent current (1.1 mA/amp) and lower GBP (10 MHz same, but phase margin reduced). | Superior for long-term DC stability in data loggers; limited settling time (2.5 µs to 0.1%) affects multiplexed sensor systems. | Choose AD8692ARZ-REEL7 for faster settling (1 µs to 0.01%), lower THD+N (0.0006% vs. 0.0015%), and proven performance in photodiode and audio applications per published test data. |
Compared with OPA2333AIDR and MCP6V82-E/SN, AD8692ARZ-REEL7 offers superior AC performance (lower THD+N, no chopper artifacts), faster settling, and better noise spectral density above 10 Hz - making it the preferred choice for mixed-signal applications demanding both precision DC accuracy and clean high-frequency response.

FAQ
What is the operating temperature range for AD8692ARZ-REEL7?
The AD8692ARZ-REEL7 is specified for continuous operation from −40°C to +125°C. This extended industrial temperature range is validated across all key parameters including offset voltage, drift, supply current, and output swing - ensuring reliability in automotive engine compartments, industrial PLCs, and outdoor environmental sensors. The SOIC package's θJA of 158°C/W supports thermal design within this envelope when power dissipation remains below 120 mW.
Does AD8692ARZ-REEL7 support single-supply operation?
Yes, AD8692ARZ-REEL7 is fully characterized for single-supply operation from 2.7 V to 6 V. Its rail-to-rail output stage delivers voltage swings within 20–40 mV of both supply rails at 1 mA load, and its input common-mode range extends to −0.3 V below V– and +3.9 V above V– at 5 V supply - enabling direct interfacing with microcontroller ADCs and DACs without level-shifting circuitry.
What is the maximum capacitive load AD8692ARZ-REEL7 can drive stably?
AD8692ARZ-REEL7 maintains stability with capacitive loads up to 200 pF when configured as a unity-gain follower, as verified in Figure 19 and Figure 20 of the Rev. F datasheet. For loads exceeding 100 pF, Analog Devices recommends adding a 10–50 Ω series resistor between the output pin and the capacitor to isolate the amplifier's output impedance from the reactive load - preserving phase margin above 60° and preventing peaking or oscillation.
Is AD8692ARZ-REEL7 pin-compatible with other dual op-amps in SOIC-8?
No, AD8692ARZ-REEL7 uses a non-standard SOIC-8 pinout: Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = V+, Pin 6 = +IN B, Pin 7 = OUT B, Pin 8 = –IN B. This differs from industry-standard dual op-amps like LM358 (Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = +IN B, Pin 6 = –IN B, Pin 7 = OUT B, Pin 8 = V+). PCB layout must follow Figure 3 in the datasheet.
What packaging and reel options are available for AD8692ARZ-REEL7?
AD8692ARZ-REEL7 is supplied in an 8-lead narrow-body SOIC (R-8) package on a 7-inch tape-and-reel per JEDEC J-STD-020, with 2,500 units per reel. The "REEL7" suffix explicitly denotes this configuration. It is RoHS-compliant (Pb-free, halogen-free) and moisture sensitivity level 1 (MSL-1), allowing indefinite floor life at ≤30°C/60% RH without baking prior to reflow.
