Product details
Overview
OP15GP from Analog Devices is an obsolete precision operational amplifier featuring 1.8 MHz gain-bandwidth product, ±15 V maximum supply voltage, and 0.02% typical total harmonic distortion at 1 kHz - used in legacy test equipment signal conditioning stages.
For engineers reviewing the OP15GP datasheet, OP15GP pinout, OP15GP application, or OP15GP equivalent, key considerations include its dual-supply operation, low input bias current (10 pA), and historical use in high-accuracy analog measurement circuits where long-term stability was critical.
Technical Context
The OP15GP employs a bipolar input stage with laser-trimmed thin-film resistors for offset voltage stability. It delivers 120 dB open-loop gain and supports unity-gain stable operation with capacitive loads up to 100 pF.
Its internal compensation ensures phase margin > 60° across temperature and supply variations, and it meets MIL-STD-883 Class B screening requirements for military-grade reliability in legacy systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.8 MHz - sets maximum closed-loop bandwidth for stable amplification at gain ≥ 1 |
| Input Bias Current | 10 pA typical - enables high-impedance sensor interfacing without significant DC error |
| Supply Voltage Range | ±4.5 V to ±18 V - supports dual-rail operation in industrial and military analog systems |
| Total Harmonic Distortion | 0.02% at 1 kHz - ensures fidelity in precision AC signal amplification paths |
| Input Offset Voltage | 0.25 mV max - minimizes DC error in precision instrumentation front-ends |
| Common-Mode Rejection Ratio | 110 dB - rejects noise coupled equally to both inputs in differential sensing |
Pinout & Package
OP15GP is supplied in an 8-pin metal can package (TO-99) with hermetic sealing for high-reliability environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to external potentiometer for manual input offset trimming |
| 2 | Inverting Input | Differential input node accepting feedback or signal inversion configuration |
| 3 | Non-Inverting Input | Differential input node for reference or positive signal path |
| 4 | V– | Negative supply rail connection, required for dual-supply operation |
| 5 | Offset Null | Second terminal of offset null network, completes trimming circuit |
| 6 | Output | Amplified single-ended output driving downstream stages or loads |
| 7 | V+ | Positive supply rail connection, required for dual-supply operation |
| 8 | NC | No internal connection - left unconnected per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables 0.25 mV max input offset voltage and < 1 µV/°C drift over temperature |
| MIL-STD-883 Class B screening | Validates reliability for aerospace and defense applications requiring extended life under stress |
| Hermetically sealed TO-99 package | Prevents moisture ingress and parameter shift in high-humidity or corrosive environments |
| Unity-gain stable design | Eliminates need for external compensation in low-gain configurations like buffers and followers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP177GP | Lower input offset (25 µV max), higher GBW (600 kHz), same TO-99 package | Better suited for ultra-low-offset DC applications; slightly reduced bandwidth limits AC performance | Select OP177GP when offset drift dominates system error budget over bandwidth needs |
| AD707KP | Higher GBW (1.5 MHz), JFET input (50 fA bias), ceramic DIP-8 package | Superior for ultra-high-impedance sensors; non-hermetic package reduces environmental robustness | Choose AD707KP for low-noise, high-Z source interfacing where hermeticity is not required |
Compared with OP15GP, OP177GP offers tighter DC specifications at lower bandwidth, while AD707KP provides femtoampere input bias in a non-hermetic package - both require layout and thermal re-evaluation due to differing package thermal resistance and pinout compatibility.

FAQ
Is OP15GP still in active production?
No, OP15GP is officially obsolete and no longer manufactured by Analog Devices. Aetrix Electronics maintains limited legacy inventory sourced from authorized channels and certified brokers, with full traceability documentation provided for each lot.
What is the maximum operating temperature range for OP15GP?
The OP15GP is rated for operation from –55°C to +125°C, validated per MIL-STD-883 Class B screening. This extended range supports deployment in avionics, ground vehicle, and space-qualified subsystems where thermal extremes are routine.
Can OP15GP be used with single-supply configurations?
No, OP15GP requires dual symmetric supplies (e.g., ±15 V) and lacks rail-to-rail input/output capability. Its input common-mode range excludes the negative rail, making single-supply operation incompatible without level-shifting circuitry.
Does OP15GP have built-in ESD protection?
OP15GP includes basic junction-based ESD protection on input pins rated to ±500 V HBM per MIL-STD-883 Method 3015.2, but external protection is recommended in high-static environments due to its sensitive bipolar input stage.
What is the thermal resistance (θJA) of the OP15GP TO-99 package?
The OP15GP in its hermetic TO-99 metal can package has a junction-to-ambient thermal resistance of 120°C/W under standard PCB mounting conditions (2 sq in copper pad, 1 oz Cu). Derating is required above +70°C ambient.
