Product details
Overview
OP4177ARZ-REEL7 from Analog Devices is a quad-channel precision operational amplifier optimized for high-accuracy sensor signal conditioning and low-drift instrumentation. It delivers 60 μV max offset voltage, 0.9 μV/°C max drift, 2 nA max input bias current, 8.5 nV/√Hz voltage noise density at 1 kHz, and operates from ±2.5 V to ±15 V supplies. It is used in RTD and thermocouple front-ends where long-term stability and low 1/f noise are critical.
For engineers reviewing the OP4177ARZ-REEL7 datasheet, OP4177ARZ-REEL7 pinout, OP4177ARZ-REEL7 application, or OP4177ARZ-REEL7 equivalent, key selection criteria include guaranteed −40°C to +125°C operation, 14-lead SOIC_N package compatibility, channel separation >120 dB at 100 kHz, and immunity to input overvoltage-induced phase reversal without external protection.
Technical Context
The OP4177ARZ-REEL7 implements a precision bipolar input stage with internal 500 Ω series resistors for ±2.5 V beyond-rail input protection and no phase reversal. Its open-loop gain exceeds 1000 V/mV with CMRR, PSRR, and AVO all ≥120 dB across temperature, enabling stable DC-coupled difference amplification in noisy industrial environments.
It achieves unity-gain stability while driving >1000 pF capacitive loads directly, and its low 400–600 μA per-amplifier supply current supports battery-powered precision measurement systems without sacrificing bandwidth (1.3 MHz GBW) or slew rate (0.7 V/μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 75 μV max at 25°C; ensures ≤120 μV error over −40°C to +125°C for high-accuracy DC measurements. |
| Offset Drift | 0.9 μV/°C max; limits thermal-induced error to <100 μV across full industrial temperature range. |
| Input Bias Current | 2 nA max; enables use with high-impedance sources like RTDs and piezoelectric sensors without significant error. |
| Voltage Noise Density | 8.5 nV/√Hz at 1 kHz; supports low-noise amplification of microvolt-level sensor outputs. |
| Supply Range | ±2.5 V to ±15 V; allows flexible single-supply (5 V to 30 V) or dual-supply operation in mixed-signal systems. |
| Channel Separation | −120 dB at 100 kHz; prevents crosstalk between channels in multi-sensor data acquisition. |
| Output Drive | ±10 mA; sufficient to drive 2 kΩ loads with rail-to-rail swing within 1.2 V of rails at ±15 V. |
Pinout & Package
OP4177ARZ-REEL7 is housed in a 14-lead narrow SOIC (SOIC_N) package (R-14 suffix), RoHS-compliant, tape-and-reel format. Thermal resistance θJA = 120°C/W.

| 12 | −IN D | Inverting input of Amp D; enables four independent precision gain stages on one die. |
| 13 | +IN D | Non-inverting input of Amp D; maintains 120 dB CMRR even at 100 kHz. |
| 14 | V− | Negative supply rail; symmetric to V+; supports true dual-supply operation with balanced PSRR. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ-REEL | Same electrical specs; packaged in 14-lead TSSOP (RU-14) with higher θJA = 240°C/W. | Better suited for space-constrained PCBs where SOIC footprint is prohibitive; thermal derating required above 50°C ambient. | Select OP4177ARUZ-REEL only when board area is critical and thermal management is verified. |
| AD8676ARZ-REEL7 | Lower noise (2.8 nV/√Hz), but higher offset (125 μV max) and narrower temp range (−40°C to +125°C not fully guaranteed). | Better for AC-coupled, wideband applications; less suitable for ultra-stable DC measurements requiring sub-100 μV drift. | Choose AD8676ARZ-REEL7 when voltage noise dominates system error budget over offset drift. |
Compared with OP4177ARUZ-REEL, OP4177ARZ-REEL7 offers lower thermal resistance and proven SOIC manufacturability; compared with AD8676ARZ-REEL7, it trades some noise performance for superior DC accuracy and guaranteed high-temp stability-making it optimal for industrial sensor front-ends demanding long-term calibration integrity.

FAQ
What is the maximum operating temperature range for OP4177ARZ-REEL7?
OP4177ARZ-REEL7 is fully specified from −40°C to +125°C. All key parameters-including offset voltage (≤120 μV), offset drift (≤0.9 μV/°C), and CMRR (≥118 dB)-are guaranteed across this full industrial temperature range, making it suitable for under-hood automotive and factory-floor applications where ambient temperatures exceed 85°C.
Does OP4177ARZ-REEL7 require external components for input overvoltage protection?
No. OP4177ARZ-REEL7 includes internal 500 Ω series resistors on both inputs, enabling safe operation with input voltages up to ±2.5 V beyond the V+ or V− supply rails without external protection. This eliminates the need for discrete diodes or current-limiting resistors in most sensor interface designs, reducing component count and layout complexity.
Can OP4177ARZ-REEL7 drive a 1000 pF capacitive load without oscillation?
Yes. OP4177ARZ-REEL7 is unity-gain stable and characterized to drive capacitive loads exceeding 1000 pF without external compensation. This capability simplifies anti-aliasing filter implementation and ADC driver design, especially in high-resolution data acquisition systems where passive filtering is required before sampling.
What is the typical supply current per amplifier in OP4177ARZ-REEL7 at ±5 V?
At ±5 V supply and 25°C, OP4177ARZ-REEL7 draws 400–500 μA per amplifier. Over the full −40°C to +125°C range, supply current increases to 500–600 μA per amplifier. This low quiescent current supports portable and energy-sensitive instrumentation without compromising precision performance.
Is OP4177ARZ-REEL7 pin-compatible with other quad op-amps in SOIC-14 packages?
OP4177ARZ-REEL7 follows the industry-standard SOIC-14 pinout for quad op-amps (e.g., pin 1 = OUT A, pin 2 = −IN A, etc.), matching common layouts used for LM324, TL084, and AD8604 families. However, due to its precision biasing and protection architecture, direct functional replacement requires verification of input common-mode range, output swing, and noise requirements in the target circuit.
