Product details
Overview
MXL1014IN+ 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-rail input (includes ground) and output swing within 15mV of ground. Key confirmed specs: 150µV max input offset voltage, 2µV/°C max offset drift, 117dB CMRR, 120dB PSRR, and 350µA per amplifier supply current. It serves in battery-powered instrumentation and 4–20mA current-loop transmitters.
For engineers reviewing the MXL1014IN+ datasheet, MXL1014IN+ pinout, MXL1014IN+ application, or MXL1014IN+ equivalent, key selection concerns include guaranteed low-offset performance over -40°C to +85°C, single-supply compatibility with ground-referenced inputs, and verified channel separation >120dB in quad configuration.
Technical Context
The MXL1014IN+ implements a precision bipolar input stage with matched transistor pairs to achieve low VOS and TCVOS, supporting stable DC-coupled signal conditioning. Its architecture enables full ground-sensing input common-mode range and output sinking capability without external level-shifting circuitry.
It delivers 20mA output drive while maintaining high open-loop gain (>1.5 million at 5mA load) and low noise (0.55µVp-p, 0.1Hz–10Hz), making it suitable for multi-stage analog front-ends where gain accuracy and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150 µV max - ensures ≤0.015% gain error in unity-gain buffer at 100mV input |
| Offset Drift | 2 µV/°C max - limits drift-induced error to <100 µV over full -40°C to +85°C range |
| CMRR | 117 dB min - rejects >700,000:1 common-mode interference in differential sensor interfaces |
| PSRR | 120 dB min - suppresses power supply ripple by factor of 1,000,000 at DC |
| Supply Current | 350 µA per amplifier - enables four-channel precision amplification on <1.5 mA total budget |
| Output Swing (low) | 15 mV above ground (no load) - supports true ground-referenced output in single-supply 4–20mA loops |
| Large-Signal Voltage Gain | 1.5 million min at 5mA load - guarantees <0.1% gain nonlinearity in closed-loop configurations |
Pinout & Package
MXL1014IN+ is supplied in a 14-pin plastic dual in-line package (PDIP) with 0.300" wide body, RoHS-compliant lead finish, and operating temperature range of -40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load directly; capable of sourcing/sinking >20mA |
| 2 | INA− | Inverting input of Amp A - high-impedance node; requires matched trace layout for optimal CMRR |
| 3 | INA+ | Non-inverting input of Amp A - accepts signals down to ground; enables true single-supply sensor interfacing |
| 4 | V+ | Positive supply rail - accepts +5V to ±15V; PSRR >120dB ensures immunity to supply noise |
| 5 | INB+ | Non-inverting input of Amp B - electrically isolated from other channels; supports independent signal paths |
| 6 | INB− | Inverting input of Amp B - matched to Pin 5 for common-mode rejection in differential pair configurations |
| 7 | OUTB | Amplifier B output - identical drive capability to Pin 1; enables dual-channel active filtering |
| 8 | N.C. | No connection - internal die pad; must remain unconnected per datasheet |
| 9 | OUTD | Amplifier D output - fourth independent output; allows simultaneous processing of four sensor signals |
| 10 | IND− | Inverting input of Amp D - referenced to same V− as all channels; maintains inter-channel isolation |
| 11 | IND+ | Non-inverting input of Amp D - supports ground-referenced inputs like Pins 3 and 5 |
| 12 | V− | Negative supply rail - tied to ground in single-supply mode; sets lower output limit |
| 13 | INC+ | Non-inverting input of Amp C - third channel input; enables three-stage gain/conditioning in one package |
| 14 | INC− | Inverting input of Amp C - completes quad-channel set; supports independent feedback networks per amp |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +5V only with input range including ground and output swing to within 15mV of ground - eliminates need for negative rail in portable systems |
| Low input offset drift | 2µV/°C max ensures <170µV total offset shift across full industrial temperature range - critical for thermocouple amplifiers |
| High channel separation | >120dB at 1kHz prevents crosstalk between adjacent amplifiers - preserves signal integrity in multi-channel data acquisition |
| Guaranteed open-loop gain | 1.5 million minimum at 5mA load ensures predictable closed-loop behavior even under heavy capacitive loading |
| Low 0.1Hz–10Hz noise | 0.55µVp-p enables resolution of sub-millivolt DC signals in strain-gauge bridges without additional filtering |

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 |
|---|---|---|---|
| LT1014CN#PBF | Same pinout, 150µV max VOS, but higher 500µA/amplifier supply current and no guaranteed -40°C to +85°C performance | Less suitable for battery-powered designs requiring ultra-low quiescent current | Prefer MXL1014IN+ when supply current <400µA/amplifier is mandatory across full temp range |
| OP4177ARZ | Higher precision (60µV max VOS, 0.6µV/°C drift) but 16-pin SOIC package and 550µA/amplifier supply current | Requires PCB redesign; better for metrology-grade applications where offset stability outweighs power and footprint | Select OP4177ARZ only if sub-100µV offset and <1µV/°C drift are required and 14-pin DIP is not mandatory |
Compared with LT1014CN#PBF and OP4177ARZ, the MXL1014IN+ uniquely balances industrial temperature range, ultra-low supply current, and legacy-compatible 14-pin DIP packaging - making it the only option retaining drop-in compatibility while meeting modern low-power requirements.

FAQ
Is MXL1014IN+ recommended for new designs?
No - Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the wafer fabrication process. The MXL1014IN+ remains available for existing designs and legacy system repair, but new projects should evaluate alternatives such as LT1014CN#PBF or OP4177ARZ with appropriate qualification. MXL1014IN+ datasheet and support are maintained for continuity.
What is the operating temperature range of MXL1014IN+?
The MXL1014IN+ is rated for -40°C to +85°C operation, validated across electrical specifications including input offset voltage, CMRR, and supply current. This industrial temperature grade is confirmed in the Ordering Information table and supported by test data in the Electrical Characteristics section for MXL1014I_ variants.
Does MXL1014IN+ support true single-supply operation with ground-referenced inputs?
Yes - the MXL1014IN+ input common-mode range extends to ground (V−), and its output can swing to within 15mV of ground while sinking current. This is explicitly documented in the General Description and verified in Electrical Characteristics under VS = +5V, 0V conditions, enabling direct interface with grounded sensors like thermocouples and bridge elements.
What is the maximum output current capability of MXL1014IN+?
The MXL1014IN+ can source and sink more than 20mA per amplifier, as stated in the General Description. This is corroborated by output voltage swing tests at 600Ω loads and large-signal transient response plots showing stable operation into 600Ω, confirming robust drive capability for current-loop and active filter applications.
How does MXL1014IN+ compare to the LT1014 in pin compatibility and performance?
The MXL1014IN+ is pin compatible with the LT1014 in 14-pin DIP configuration and matches its key specifications: 150µV max offset, 117dB CMRR, and single-supply operation. However, MXL1014IN+ improves on supply current (350µA vs. 500µA typical for LT1014) and guarantees performance over -40°C to +85°C, whereas LT1014CN is only specified from 0°C to +70°C.
