Product details
Overview
OP15GS-REEL from Analog Devices is an obsolete precision operational amplifier with ±15 V supply capability, 1.5 MHz gain-bandwidth product, 0.5 mV input offset voltage, and SOIC-8 package; used in legacy industrial instrumentation signal conditioning circuits.
For engineers reviewing the OP15GS-REEL datasheet, OP15GS-REEL pinout, OP15GS-REEL application, or OP15GS-REEL equivalent, key considerations include its discontinued status, SOIC-8 footprint compatibility, rail-to-rail output limitation, and need for verified drop-in alternatives in active designs.
Technical Context
The OP15GS-REEL implements a bipolar-input op-amp architecture optimized for DC precision and low-noise AC performance. It supports dual-supply operation up to ±15 V and delivers 1.5 MHz unity-gain bandwidth with 0.5 mV max input offset voltage at 25°C.
Its SOIC-8 package integrates standard op-amp pinout (non-inverting input, inverting input, output, V+, V−, and three NC pins). Output swing reaches within 1.5 V of each rail under 2 kΩ load, limiting true rail-to-rail use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±15 V max - supports legacy industrial analog signal chains requiring dual-rail operation |
| Gain-Bandwidth Product | 1.5 MHz - enables stable closed-loop gain up to ~100 at 15 kHz with phase margin >45° |
| Input Offset Voltage | 0.5 mV max - ensures ≤0.5% error in 1 V full-scale DC-coupled measurement paths |
| Input Bias Current | 50 nA max - compatible with high-impedance sensor interfaces without significant loading error |
| Output Swing | Within 1.5 V of rails - requires ≥3 V headroom for full-scale output in ±15 V systems |
| Package | SOIC-8 - industry-standard 150 mil body width, 1.27 mm pitch, surface-mount compatible |
Pinout & Package
OP15GS-REEL uses a standard SOIC-8 package with 1.27 mm lead pitch and 3.9 mm × 4.9 mm body dimensions. Pin 1 is marked with a notch or dot; pin numbering follows JEDEC MS-012AA convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Adjusts input offset via external potentiometer; unused in most applications |
| 2 | Inverting Input (−) | Primary feedback node in standard op-amp configurations |
| 3 | Non-Inverting Input (+) | Reference input for follower, summing, or differential configurations |
| 4 | V− | Negative supply connection; must be decoupled to ground near device |
| 5 | Offset Null | Second terminal for offset trim; tied to pin 1 for calibration |
| 6 | Output | Single-ended voltage source capable of sourcing/sinking ±10 mA |
| 7 | V+ | Positive supply connection; requires local 0.1 µF ceramic decoupling |
| 8 | No Connect | Internally unconnected; left floating per datasheet recommendation |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Offset Voltage | 0.5 mV max enables sub-0.1% accuracy in 5 V reference-based transducer amplifiers |
| Bipolar Input Stage | Supports low-noise, low-drift performance with 50 nA input bias current at 25°C |
| Dual-Supply Operation | ±15 V rating matches legacy industrial power rails and avoids level-shifting circuitry |
| SOIC-8 Footprint | Enables direct replacement in existing PCB layouts designed for industry-standard op-amps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Zero-drift architecture, 1 µV offset, 2.5 MHz GBW, same SOIC-8 package | Higher DC accuracy and bandwidth; requires updated compensation for stability | Preferred for new designs needing improved offset drift and noise performance |
| OP27GSZ | Bipolar input, 25 µV offset, 8 MHz GBW, SOIC-8 package | Higher speed and lower offset but increased supply current (4.5 mA vs. 2.2 mA) | Suitable when bandwidth >1.5 MHz is required and power budget allows +100% quiescent current |
Compared with OP15GS-REEL, AD8628ARZ offers superior DC precision and bandwidth at higher cost and different internal topology, while OP27GSZ provides faster response with greater power consumption-both require validation of loop stability and thermal layout in legacy footprints.

FAQ
Is OP15GS-REEL still in production?
No, OP15GS-REEL is officially obsolete and no longer manufactured by Analog Devices. Aetrix Electronics maintains limited legacy stock for repair and maintenance of installed base systems. New designs should select verified alternatives such as AD8628ARZ or OP27GSZ after full electrical and thermal validation.
What is the pinout configuration of OP15GS-REEL?
The OP15GS-REEL uses a standard SOIC-8 pinout: Pin 1 (Offset Null), Pin 2 (Inverting Input), Pin 3 (Non-Inverting Input), Pin 4 (V−), Pin 5 (Offset Null), Pin 6 (Output), Pin 7 (V+), and Pin 8 (No Connect). This matches JEDEC MS-012AA and is identical to OP07 and OP27 footprints.
Can OP15GS-REEL be replaced with OP27GSZ in the same PCB layout?
Yes, OP15GS-REEL and OP27GSZ share identical SOIC-8 packaging and pinout, enabling direct PCB footprint reuse. However, OP27GSZ draws nearly double the quiescent current (4.5 mA vs. 2.2 mA) and has higher bandwidth, requiring verification of thermal dissipation and loop compensation in the target circuit.
What is the maximum output current capability of OP15GS-REEL?
The OP15GS-REEL can source or sink up to ±10 mA into resistive loads while maintaining specified linearity and slew rate. Output current is limited by internal protection circuitry and decreases under heavy capacitive loading or elevated ambient temperature above 25°C.
Does OP15GS-REEL support single-supply operation?
No, OP15GS-REEL is specified only for dual-supply operation (±3 V to ±15 V). Its input common-mode range does not extend to the negative rail, and output swing is asymmetric under single-supply biasing-making it unsuitable for true single-rail applications without external level-shifting circuitry.
