Product details
Overview
MXL1014IN from Maxim Integrated is a precision quad operational amplifier in 14-pin plastic DIP package, rated for -40°C to +85°C operation. It delivers 40µV max input offset voltage, 0.3µV/°C drift, 117dB CMRR, 120dB PSRR, and 350µA per amplifier supply current - enabling high-accuracy signal conditioning in single-supply systems down to +5V.
For engineers reviewing the MXL1014IN datasheet, MXL1014IN pinout, MXL1014IN application, or MXL1014IN equivalent, key selection considerations include guaranteed rail-to-rail output swing near ground under sink load, low 0.55µVp-p (0.1–10Hz) input noise, and pin compatibility with LT1014 and industry-standard 14-pin DIP op amp footprints.
Technical Context
The MXL1014IN implements a bipolar-input, precision op amp architecture optimized for DC accuracy and low-noise performance in battery-powered instrumentation. Its input stage supports common-mode voltage down to ground on single +5V supply, and its output stage drives ≥20mA while swinging within 15mV of ground (no load) and 220mV (1mA sink).
It features matched amplifier pairs with >120dB channel separation and guaranteed large-signal voltage gain of 1.5 million (min) at 2kΩ load. The design meets stringent long-term offset stability requirements and includes internal compensation for unity-gain stable operation without external components.
Key Specifications

|---|---|
| Input Offset Voltage | 40 µV max - enables sub-100µV system-level DC error in precision sensor front-ends |
| Offset Voltage Drift | 0.3 µV/°C typ - ensures <1µV total drift over full -40°C to +85°C industrial range |
| CMRR | 117 dB min - rejects >700,000:1 common-mode interference in differential measurements |
| PSRR | 120 dB min - maintains accuracy despite ±2V to ±18V supply variation or ripple |
| Supply Current per Amp | 350 µA typ - allows four-channel precision amplification within 1.4mA total budget |
| Output Swing (low) | 15 mV above ground (no load) - supports true single-supply operation with grounded reference |
| Input Noise (0.1–10Hz) | 0.55 µVp-p - critical for thermocouple and strain-gauge signal integrity below 10Hz |
Pinout & Package
MXL1014IN is supplied in a 14-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole footprint. Pin 1 is marked by notch or dot; pin numbering follows standard DIP convention (counterclockwise from notch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - capable of sourcing/sinking >20mA, swings to within 15mV of ground |
| 2 | INA− | Inverting input of Amp A - high-impedance node (70MΩ min), matched to non-inverting input |
| 3 | INA+ | Non-inverting input of Amp A - extends to ground on single +5V supply |
| 4 | V+ | Positive supply rail - accepts +5V to +18V (or ±2V to ±18V dual supply) |
| 5 | INB+ | Non-inverting input of Amp B - electrically identical to INA+, supports rail-to-rail common-mode |
| 6 | INB− | Inverting input of Amp B - matched bias current and offset characteristics with INA− |
| 7 | OUTB | Amplifier B output - fully independent, >120dB channel separation from OUTA |
| 8 | N.C. | No connection - internally unused, must remain unconnected |
| 9 | OUTD | Amplifier D output - identical drive capability and swing specification as OUTA |
| 10 | IND− | Inverting input of Amp D - matched offset and noise performance across all four channels |
| 11 | IND+ | Non-inverting input of Amp D - shares same input voltage range and CMRR as INA+ |
| 12 | V− | Negative supply rail - connects to ground on single +5V operation |
| 13 | INC+ | Non-inverting input of Amp C - enables simultaneous multi-channel signal processing |
| 14 | INC− | Inverting input of Amp C - supports independent feedback networks per channel |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +5V only with input range extending to ground and output swing to within 15mV of ground |
| Low 1/f noise | 0.55µVp-p (0.1–10Hz) - minimizes drift-induced errors in slow-moving sensor signals |
| High open-loop gain | 1.5 million minimum at 2kΩ load - ensures <0.1% gain error in closed-loop configurations |
| Guaranteed channel separation | >120dB - prevents crosstalk between independent signal paths in multi-channel instrumentation |
| Low input bias current | 12nA max - preserves accuracy when driving high-impedance sources like piezoresistive sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1014CN | Same 14-pin DIP package, 50µV max VOS, 0.6µV/°C TCVOS - slightly higher offset and drift than MXL1014IN | Valid for legacy designs requiring MIL-qualified replacements; lower PSRR (110dB) affects noisy supply environments | Preferred where LT1014 footprint compatibility is mandatory and tighter drift specs are not required |
| OP297GP | 14-pin DIP, 25µV max VOS, 0.1µV/°C drift - superior DC specs but 750µA per amp supply current | Not suitable for ultra-low-power battery operation; better for mains-powered lab equipment demanding lowest drift | Select when long-term stability outweighs power budget constraints, especially in calibration-grade instruments |
Compared with LT1014CN and OP297GP, the MXL1014IN offers the optimal balance of low offset (40µV), ultra-low drift (0.3µV/°C), and minimal quiescent current (350µA) in the 14-pin DIP form factor - making it uniquely suited for industrial portable instrumentation where all three parameters are simultaneously critical.

FAQ
Is MXL1014IN still recommended for new designs?
No - Maxim explicitly states MXL1014IN is "Not Recommended for New Designs" due to discontinuation of its wafer fabrication process. It remains available for existing designs and legacy support, but engineers should evaluate LT1014CN or OP297GP as alternatives before initiating new projects. The MXL1014IN datasheet is retained for reference, and Aetrix Electronics maintains inventory for continuity of production runs.
What is the operating temperature range of MXL1014IN?
The MXL1014IN is specified for -40°C to +85°C operation, qualifying it for industrial-grade applications including factory automation, outdoor instrumentation, and automotive under-hood monitoring (non-safety-critical). This range is confirmed in the Ordering Information table and validated across all key DC parameters including input offset voltage, bias current, and PSRR.
Does MXL1014IN support true single-supply operation with ground-referenced inputs and outputs?
Yes - the MXL1014IN supports true single-supply operation from +5V. Its input common-mode range extends to ground, and its output can swing to within 15mV of ground with no load (and to 220mV while sinking 1mA), enabling direct interfacing with ADCs and microcontrollers referenced to the same ground. This behavior is verified in both ±15V and +5V/0V test conditions.
What are the absolute maximum supply voltage ratings for MXL1014IN?
The MXL1014IN has an absolute maximum supply voltage rating of ±22V for dual supplies, or +22V relative to V− when used in single-supply mode. Exceeding these limits risks permanent damage. Derating guidelines apply: for 14-pin plastic DIP packages, continuous power dissipation must be limited to 800mW at +70°C, decreasing by 10mW/°C above that temperature.
How does MXL1014IN compare to the LT1014 in terms of pin compatibility and performance?
The MXL1014IN is pin compatible with the LT1014 in 14-pin DIP configuration, sharing identical pinout, supply connections, and amplifier channel mapping. Performance-wise, MXL1014IN matches or exceeds LT1014 in key specs: 40µV vs. 50µV max VOS, 0.3µV/°C vs. 0.6µV/°C max drift, and 117dB vs. 110dB min CMRR - making it a functional upgrade path for existing LT1014 designs.
