Product details
Overview
OP4177AR-REEL from Analog Devices is a quad-channel precision operational amplifier optimized for high-accuracy signal conditioning in industrial and instrumentation 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 thermocouple amplification, RTD bridge sensing, and shunt-based current measurement with sub-μV-level DC stability.
For engineers reviewing the OP4177AR-REEL datasheet, OP4177AR-REEL pinout, OP4177AR-REEL application, or OP4177AR-REEL equivalent, key selection criteria include guaranteed −40°C to +125°C operation, 1.3 MHz gain bandwidth, unity-gain stability, no phase reversal, and internal input overvoltage protection beyond supply rails - all in a 14-lead SOIC_N package suitable for space-constrained, high-reliability PCB layouts.
Technical Context
The OP4177AR-REEL implements a precision bipolar input stage with proprietary process technology to achieve ultra-low offset drift and bias current temperature insensitivity. Its open-loop gain exceeds 1000 V/mV with CMRR, PSRR, and AVO all ≥120 dB across −40°C to +125°C, ensuring stable DC accuracy in varying supply and common-mode conditions.
It features internal 500 Ω series input resistors that enable safe operation with input signals up to 2.5 V beyond either supply rail without external protection. Output drive capability supports ±10 mA into 2 kΩ loads with rail-to-rail swing within 1.2 V of each supply, and it remains stable driving >1000 pF capacitive loads without compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 75 μV max (25°C); ensures ≤120 μV over full −40°C to +125°C range - critical for <10 ppm DC error in precision sensor front-ends. |
| Offset Drift | 0.9 μV/°C max - limits thermal-induced error to <80 μV across 90°C ambient shift, enabling uncalibrated operation in harsh environments. |
| Input Bias Current | ±2 nA max (−40°C to +125°C) - enables use with high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without significant offset shift. |
| Voltage Noise Density | 8.5 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals from strain gauges and thermocouples. |
| Gain Bandwidth Product | 1.3 MHz - provides sufficient bandwidth for 100 Hz–1 kHz sensor signal conditioning while maintaining DC precision. |
| Supply Current per Amp | 500 μA max (−40°C to +125°C) - allows four independent channels in <2 mA total quiescent current, ideal for battery-backed or energy-conscious designs. |
| Common-Mode Rejection | 118 dB min (−40°C to +125°C) - rejects interference from noisy industrial power rails and ground loops in 4–20 mA loop receivers. |

FAQ
What is the maximum operating temperature range for OP4177AR-REEL?
OP4177AR-REEL is fully specified from −40°C to +125°C, with all key parameters - including offset voltage, drift, CMRR, and PSRR - guaranteed across this range. This makes OP4177AR-REEL suitable for under-hood automotive, industrial PLC, and outdoor telecom applications where ambient temperatures exceed 85°C. The 14-lead SOIC_N package supports reliable thermal dissipation at elevated junction temperatures.
Does OP4177AR-REEL require external input protection resistors?
No, OP4177AR-REEL includes internal 500 Ω series input resistors that protect both inverting and non-inverting inputs against overvoltage conditions up to ±2.5 V beyond the supply rails. This eliminates the need for external protection components in most industrial sensor interfaces. If input transients exceed ±2.5 V beyond supplies, an external series resistor may be added - but OP4177AR-REEL itself does not require it for standard operation.
Can OP4177AR-REEL drive a 1000 pF capacitive load without oscillation?
Yes, OP4177AR-REEL is explicitly characterized to remain stable driving capacitive loads exceeding 1000 pF without external compensation. This is confirmed in the datasheet's "Capacitive Load Drive" section and typical performance curves. The internal compensation ensures monotonic step response and no peaking up to 1000 pF, making OP4177AR-REEL ideal for driving ADC input capacitors, long cables, or active filter stages directly.
What is the typical supply current per amplifier in OP4177AR-REEL at +25°C?
At +25°C and ±5 V supplies, OP4177AR-REEL draws 400 μA per amplifier (1.6 mA total for all four channels), rising to 500 μA per amplifier at +125°C. This low quiescent current enables four independent precision channels in <2.5 mA total, supporting energy-efficient designs in battery-backed instrumentation and portable test equipment without sacrificing DC accuracy.
Is OP4177AR-REEL pin-compatible with other quad op-amps like the OP4177ARZ-REEL?
Yes, OP4177AR-REEL and OP4177ARZ-REEL share identical pinout, package (14-lead SOIC_N), and electrical specifications - differing only in lead finish (SnPb vs. Pb-free) and RoHS compliance. No PCB layout changes are required when substituting between them. Both are drop-in replacements in existing designs, with OP4177AR-REEL supporting legacy solder reflow profiles and OP4177ARZ-REEL meeting modern environmental requirements.
