Product details
Overview
OP14AJ from Analog Devices is an obsolete precision operational amplifier with JFET input, 1.8 MHz gain-bandwidth product, ±15 V supply rating, and 0.0005% THD+N at 1 kHz; used in legacy test equipment signal conditioning stages.
For engineers reviewing the OP14AJ datasheet, OP14AJ pinout, OP14AJ application, or OP14AJ equivalent, key considerations include its discontinued status, JFET-input architecture, low distortion performance, and compatibility with dual-supply analog front-ends requiring high DC precision.
Technical Context
The OP14AJ employs a matched JFET input stage enabling ultra-low input bias current (30 pA typical) and high common-mode rejection (110 dB). It delivers rail-to-rail output swing within 1.5 V of each rail under 2 kΩ load and maintains 0.1% settling time of 10 µs to 10 V step.
Designed for DC-coupled precision systems, it features internal frequency compensation, no external capacitor required, and operates over –25°C to +85°C ambient temperature range with thermal shutdown protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.8 MHz - supports stable closed-loop operation up to 100 kHz with unity-gain stability |
| Input Bias Current | 30 pA typical - enables high-impedance sensor interfacing without significant DC error |
| THD+N @ 1 kHz | 0.0005% - meets audio-grade linearity requirements in measurement instrumentation |
| Supply Voltage Range | ±15 V - compatible with legacy industrial analog signal chains using standard dual supplies |
| Common-Mode Rejection | 110 dB - rejects noise in differential sensing configurations with high accuracy |
| Output Voltage Swing | Within 1.5 V of rails - provides maximum dynamic range into 2 kΩ loads |
Pinout & Package
OP14AJ is supplied in an 8-pin metal can package (TO-99), hermetically sealed for long-term reliability in demanding environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to external potentiometer for trimming input offset voltage to ≤25 µV |
| 2 | Inverting Input | Differential input node with 30 pA bias current and 110 dB CMRR |
| 3 | Non-Inverting Input | Differential input node matched to Pin 2 for balanced common-mode rejection |
| 4 | V– | Negative supply terminal, rated for –15 V with internal thermal shutdown |
| 5 | Offset Null | Second terminal of offset trim network, used with Pin 1 for DC calibration |
| 6 | Output | Capable of driving 2 kΩ loads with 10 µs 0.1% settling to 10 V step |
| 7 | V+ | Positive supply terminal, rated for +15 V with internal thermal shutdown |
| 8 | NC | No internal connection - electrically isolated, must be left unconnected |
Key Features
| Feature | Design Value |
|---|---|
| JFET input stage | Enables 30 pA input bias current for high-impedance transducer interfacing |
| Internal frequency compensation | Guarantees unity-gain stability without external components |
| Offset null terminals (Pins 1 & 5) | Supports manual calibration to reduce input offset voltage below 25 µV |
| Rail-to-rail output swing margin | Delivers 27 Vpp output into 2 kΩ on ±15 V supplies, maximizing signal headroom |
| Hermetic TO-99 metal can | Provides long-term parameter stability in humid or thermally cycling environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher 8 MHz GBW, 10 nV/√Hz voltage noise, but 100 nA input bias current | Better AC performance; unsuitable for >1 MΩ source impedances due to higher bias current | Select OP27GP only when bandwidth and noise dominate over input impedance constraints |
| AD822ARZ | Rail-to-rail output, 1.8 MHz GBW, 25 pA input bias, but requires ±5 V to ±15 V dual supply | Compatible with modern low-voltage systems; lacks hermetic TO-99 packaging | Choose AD822ARZ for new designs needing surface-mount packaging and extended supply flexibility |
Compared with OP14AJ, OP27GP trades ultra-low input bias for higher speed and noise performance, while AD822ARZ offers modern packaging and rail-to-rail output but no hermetic seal-both require layout and calibration revalidation in legacy-replacement scenarios.

FAQ
Is OP14AJ still in active production?
No, OP14AJ is officially obsolete and no longer manufactured by Analog Devices. Aetrix Electronics maintains limited legacy stock sourced from verified channels with full traceability, intended for repair and continuity use in end-of-life systems.
What is the pin configuration of OP14AJ?
The OP14AJ uses an 8-pin TO-99 metal can package with standardized pinout: Pin 1 and Pin 5 are offset null terminals, Pins 2 and 3 are inverting and non-inverting inputs, Pin 4 is V–, Pin 6 is output, Pin 7 is V+, and Pin 8 is NC. This matches JEDEC TO-99 mechanical and electrical conventions.
Can OP14AJ replace OP07 or OP177 in existing designs?
OP14AJ is not a direct replacement for OP07 or OP177 due to differences in input stage topology, offset nulling method, and thermal characteristics. While all are precision op-amps, OP14AJ's JFET input and TO-99 package require validation of bias current sensitivity and thermal response in the target circuit before substitution.
Does OP14AJ support single-supply operation?
No, OP14AJ is specified and characterized only for dual-supply operation from ±15 V. Its input common-mode range does not extend to the negative rail, and output swing is asymmetric under single-supply conditions-operation outside ±15 V dual supply is not supported or guaranteed.
What is the maximum load drive capability of OP14AJ?
OP14AJ is rated to drive resistive loads down to 2 kΩ while maintaining 0.1% settling time of 10 µs and THD+N ≤0.0005% at 1 kHz. Driving lower-impedance loads may degrade linearity, bandwidth, and thermal stability, and is not recommended per the original Analog Devices specification.
