Product details
Overview
OP4177ARZ-REEL from Analog Devices is a quad-channel, precision low-noise operational amplifier optimized for high-accuracy sensor signal conditioning and industrial measurement systems. 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 - enabling stable performance in RTD, thermocouple, and shunt current sensing circuits.
For engineers reviewing the OP4177ARZ-REEL datasheet, OP4177ARZ-REEL pinout, OP4177ARZ-REEL application, or OP4177ARZ-REEL equivalent, this page provides verified specifications, validated 14-lead SOIC_N package mapping, confirmed quad-amplifier channel separation (−120 dB @ 100 kHz), temperature-stable CMRR/PSRR (>114 dB over −40°C to +125°C), and real-world design meaning for low-drift, low-noise analog front-ends.
Technical Context
The OP4177ARZ-REEL implements a precision bipolar-input architecture with internal 500 Ω series input protection resistors, enabling robust operation with input signals up to 2.5 V beyond supply rails without phase reversal. Its unity-gain stability and 1.3 MHz gain bandwidth support precision filter and closed-loop instrumentation designs.
Each of its four amplifiers features matched offset and drift characteristics across temperature, with guaranteed 120 dB minimum CMRR and PSRR over full −40°C to +125°C operating range - critical for DC-coupled sensor interfaces where common-mode rejection directly impacts measurement accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 75 μV max (25°C); ensures ≤120 μV error over full −40°C to +125°C - critical for sub-mV-level sensor output amplification |
| Offset Drift | 0.9 μV/°C max; limits thermal-induced error to <11 μV over 125°C ambient swing - enables uncalibrated operation in industrial enclosures |
| Input Bias Current | 2 nA max over temperature; allows use with high-impedance sources (e.g., 10 MΩ RTD bridges) without significant offset shift |
| Voltage Noise Density | 8.5 nV/√Hz at 1 kHz; supports low-noise amplification of microvolt-level thermocouple outputs without dominating source noise |
| Supply Current per Amp | 500 μA max (−40°C to +125°C); enables 2 mA total quiescent draw for quad-channel precision - suitable for battery-backed data loggers |
| CMRR / PSRR | 114 dB min over full temp range; rejects power supply ripple and ground noise in shared-rail industrial systems |
| Output Swing | ±14.1 V into 1 mA load (±15 V supplies); delivers rail-to-rail usable dynamic range for 16-bit ADC interfacing |
Pinout & Package
OP4177ARZ-REEL is packaged in a 14-lead narrow SOIC (R-14) with standard surface-mount footprint and tape-and-reel delivery (REEL suffix). Thermal resistance θJA = 120°C/W enables reliable operation at full rated temperature without forced airflow.

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 - requires enhanced thermal management | Better suited for space-constrained PCBs where SOIC footprint is unavailable; not recommended for >85°C ambient without derating | Select OP4177ARUZ-REEL only when board area is primary constraint and thermal margin permits |
| AD8628ARZ-REEL | Chopper-stabilized architecture; 1 μV max offset but higher 1/f noise (0.1–10 Hz) and 10× higher supply current (4 mA) | Superior DC accuracy for ultra-low-drift applications; unsuitable for wideband sensor signals due to chopping artifacts | Choose AD8628ARZ-REEL only when sub-μV offset dominates requirements and bandwidth <10 kHz suffices |
Compared with OP4177ARZ-REEL, OP4177ARUZ-REEL offers identical precision but reduced thermal performance in compact layouts, while AD8628ARZ-REEL trades bandwidth and noise floor for ultra-low offset - making OP4177ARZ-REEL optimal for general-purpose high-accuracy, wide-temperature, low-power analog front-ends.

FAQ
What is the maximum operating temperature range for OP4177ARZ-REEL?
OP4177ARZ-REEL is fully specified from −40°C to +125°C. All key parameters - including offset voltage (≤120 μV), offset drift (≤0.9 μV/°C), CMRR (≥114 dB), and PSRR (≥114 dB) - are guaranteed across this entire range, making it suitable for under-hood automotive, industrial motor control, and outdoor telecom equipment where ambient temperatures exceed 85°C.
Does OP4177ARZ-REEL require external compensation for unity-gain stability?
No, OP4177ARZ-REEL is internally compensated and unity-gain stable. It can be used in buffer, follower, or gain-of-one configurations without external capacitors or resistors. This simplifies layout and eliminates risk of instability due to stray capacitance - a key advantage over decompensated precision op-amps like OPA277.
Can OP4177ARZ-REEL safely handle input voltages beyond its supply rails?
Yes. OP4177ARZ-REEL includes internal 500 Ω series input resistors that allow input signals up to 2.5 V beyond either supply rail (V+ or V−) without damage or phase reversal. For overvoltage conditions exceeding this margin, an external series resistor must be added per the formula RS ≤ (VIN − VS) / 5 mA.
What is the typical voltage noise density of OP4177ARZ-REEL at 1 kHz?
The typical voltage noise density of OP4177ARZ-REEL at 1 kHz is 7.9 nV/√Hz, with a maximum of 8.5 nV/√Hz. This low broadband noise, combined with 0.4 μV p-p 0.1 Hz to 10 Hz flicker noise, makes OP4177ARZ-REEL ideal for amplifying low-frequency sensor outputs such as thermocouples and strain gauges without compromising resolution.
How does channel separation performance impact multi-sensor systems using OP4177ARZ-REEL?
OP4177ARZ-REEL guarantees −120 dB channel separation at 100 kHz, meaning signal coupling between any two of its four amplifiers is less than 1 μV per volt of output. This enables simultaneous sampling of multiple sensors (e.g., temperature, pressure, current) on a single IC without measurable crosstalk - reducing component count and improving system-level accuracy in data acquisition modules.
