Product details
Overview
MXL1014DN from Maxim Integrated is a precision quad operational amplifier in 14-pin plastic DIP package, designed for single-supply operation down to +5V with rail-to-ground input and output swing. It delivers 40µV max offset voltage, 0.3µV/°C drift, 117dB CMRR, and 20mA output drive per channel-enabling high-accuracy signal conditioning in battery-powered instrumentation.
For engineers reviewing the MXL1014DN datasheet, MXL1014DN pinout, MXL1014DN application, or MXL1014DN equivalent, key selection considerations include guaranteed low-offset performance at 0°C to +70°C, compatibility with legacy LT1014-based layouts, and verified operation in 4–20mA transmitter front-ends and multi-channel active filter stages.
Technical Context
The MXL1014DN implements fully differential input stages with matched transistor pairs to achieve 40µV initial offset and 0.3µV/°C TCVOS across temperature. Its output stage supports true ground-sinking capability without external pull-downs, enabling direct interfacing with ADC reference inputs and current-loop loads.
It features internal compensation for unity-gain stability, operates from ±15V or single +5V/0V rails, and maintains ≥1.5 million open-loop gain at 5mA load-critical for precision integrators and low-drift instrumentation amplifier topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 40 µV max - enables sub-100µV system-level error in strain-gauge bridges without trimming |
| Offset Drift (TCVOS) | 0.3 µV/°C - ensures <100 µV total drift over 0°C to +70°C operating range |
| CMRR | 117 dB - rejects common-mode noise in thermocouple amplifiers with >100kΩ source impedance |
| PSRR | 120 dB - suppresses ripple on +5V supply in portable data loggers |
| Supply Current | 350 µA per amplifier - allows four channels to operate within 1.4 mA total for coin-cell-powered devices |
| Output Drive | ±20 mA - drives 600Ω loads directly in 4–20mA loop transmitters without external buffers |
| Input Range | Includes ground - eliminates level-shifting circuitry when interfacing with 0–5V sensors |
| Output Swing | Within 15 mV of ground (no load) - supports accurate zero-reference settling in precision comparators |
Pinout & Package
MXL1014DN is housed in a 14-pin plastic dual in-line package (PDIP) with 0.3" body width and standard through-hole footprint compatible with industry-standard socketing and wave-solder processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1014DN | Same 14-pin DIP package; 150µV max offset (vs. 40µV for MXL1014DN); 0.6µV/°C drift | Higher offset and drift limit use in Class I instrumentation where calibration intervals exceed 6 months | Select LT1014DN only if legacy LT1014 layout reuse is mandatory and tighter offset specs are not required |
| OP4177ARZ | 14-pin SOIC package (not pin-compatible); 25µV max offset; 0.6µV/°C drift; 500µA supply current per amp | Requires PCB redesign but offers lower noise (8nV/√Hz) and better PSRR (130dB) for high-EMI environments | Choose OP4177ARZ for new designs needing improved noise performance and extended temperature support (−40°C to +125°C) |
Compared with LT1014DN and OP4177ARZ, the MXL1014DN provides the lowest offset and drift in a through-hole DIP package, making it optimal for repair, legacy replacement, and prototyping where mechanical robustness and hand-solderability are prioritized over ultra-low noise or extended temperature range.

FAQ
Is MXL1014DN still recommended for new designs?
No-Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the wafer process used to manufacture MXL1014DN. However, Aetrix Electronics maintains inventory for legacy support, repair, and continuity programs. For new designs, consult Maxim's official replacement guidance or consider OP4177ARZ as a modern alternative with superior specs and active production status. MXL1014DN remains fully functional and supported for existing applications.
What is the operating temperature range of MXL1014DN?
The MXL1014DN is rated for 0°C to +70°C ambient operation, as confirmed by its ordering code suffix "N" and the "MXL1014CN" and "MXL1014DN" entries in the official Maxim ordering table. This commercial-grade range aligns with typical bench instrumentation and industrial control panel environments where forced-air cooling is available. The device meets all electrical specifications-including 40µV offset and 0.3µV/°C drift-within this range.
Does MXL1014DN support true single-supply operation with rail-to-rail inputs and outputs?
Yes-the MXL1014DN supports true single-supply operation from +5V/0V. Its input common-mode range extends to the negative rail (ground), and its output swings to within 15mV of ground under no-load conditions. This eliminates the need for level-shifting circuitry when interfacing with 0–5V sensors or microcontroller ADC references. All four amplifiers in the MXL1014DN exhibit this behavior consistently across the 0°C to +70°C range.
What are the absolute maximum supply voltage ratings for MXL1014DN?
The MXL1014DN has an absolute maximum supply voltage rating of ±22V across V+ and V− pins. When operated from a single +5V supply, V− must be connected to ground. Exceeding ±22V risks permanent damage, and operation above the recommended 0°C to +70°C temperature range may degrade offset and drift performance. Derating guidelines specify 10.00mW/°C above +70°C for the 14-pin plastic DIP package, limiting continuous power dissipation to 800mW at +70°C.
How does MXL1014DN compare to LT1014 in terms of pin compatibility and performance?
The MXL1014DN is pin-compatible with the LT1014 in the 14-pin DIP package and shares identical pin functions (e.g., Pin 1 = OUTA, Pin 2 = INA−). However, MXL1014DN improves upon LT1014 with 40µV max offset (vs. 150µV), 0.3µV/°C drift (vs. 0.6µV/°C), and guaranteed 20mA output drive. These enhancements allow drop-in replacement in most LT1014 designs while improving accuracy and output capability-making MXL1014DN a direct performance upgrade for legacy systems.
