Product details
Overview
MXL1014CN+ from Maxim Integrated is a precision quad operational amplifier in a 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, 120dB PSRR, and 350µA per amplifier supply current - enabling high-accuracy signal conditioning in battery-powered instrumentation.
For engineers reviewing the MXL1014CN+ datasheet, MXL1014CN+ pinout, MXL1014CN+ application, or MXL1014CN+ equivalent, key selection criteria include guaranteed low-offset performance across temperature, ground-sensing capability in single-supply systems, and compatibility with legacy LT1014-based layouts requiring no PCB redesign.
Technical Context
The MXL1014CN+ implements a precision bipolar input stage with matched transistor pairs to achieve low VOS and TCVOS, supporting stable DC-coupled gain blocks. Its output stage is optimized for sourcing/sinking >20mA while maintaining linearity near ground - critical for driving 4–20mA transmitters and active filters without level-shifting circuitry.
It operates over 0°C to +70°C with ±15V or +5V/0V supplies, and features internal compensation for unity-gain stability. Channel separation exceeds 120dB at 1kHz, ensuring minimal crosstalk in multi-channel sensor interfaces where independent amplification paths are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 40 µV max - enables sub-100µV system-level error budgets in strain-gauge bridges without trimming. |
| Offset Drift | 0.3 µV/°C - ensures <1µV total drift over 0°C to +70°C ambient, critical for thermocouple amplifiers. |
| CMRR | 117 dB - rejects common-mode noise from shared power rails in multi-sensor industrial modules. |
| PSRR | 120 dB - maintains accuracy when powered from noisy +5V switchers or unregulated battery sources. |
| Supply Current | 350 µA per amplifier - allows four-channel precision amplification within 1.4mA total, ideal for portable devices. |
| Output Swing | Within 15 mV of ground (no load) - supports true single-supply 0–5V signal chains without negative rail. |
| Slew Rate | 0.2 V/µs - sufficient for <10kHz active filters and DC-coupled instrumentation with adequate phase margin. |
Pinout & Package
MXL1014CN+ is housed in a 14-pin plastic dual in-line package (PDIP), 0.300" wide, with through-hole mounting and industry-standard footprint compatible with LT1014CN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives loads down to ground; requires ≥1kΩ minimum load when sinking current. |
| 2 | INA− | Inverting input of Amp A - high-impedance node; sensitive to layout-induced leakage and noise coupling. |
| 3 | INA+ | Non-inverting input of Amp A - accepts signals down to ground; used for reference-biased sensor inputs. |
| 4 | V+ | Positive supply rail - connects to +5V or +15V; decoupling capacitor required within 1 cm. |
| 5 | INB+ | Non-inverting input of Amp B - identical electrical behavior to Pin 3; enables matched dual-path designs. |
| 6 | INB− | Inverting input of Amp B - paired with Pin 5 for differential front-end stages or instrumentation amps. |
| 7 | OUTB | Amplifier B output - electrically isolated from OUTA; supports independent feedback networks. |
| 8 | N.C. | No connection - internally unused; must remain floating, not tied to ground or supply. |
| 9 | OUTD | Amplifier D output - fourth channel output; shares same drive strength and rail-swing specs as OUTA/B/C. |
| 10 | IND− | Inverting input of Amp D - matches Pin 2/6/12; supports quad-channel threshold detection or gain blocks. |
| 11 | IND+ | Non-inverting input of Amp D - identical to Pins 3/5/13; enables synchronized multi-channel signal routing. |
| 12 | V− | Negative supply rail - connects to 0V (single-supply) or −15V (dual-supply); return path for all four amplifiers. |
| 13 | INC+ | Non-inverting input of Amp C - completes quad set; used for reference buffers or parallel filter sections. |
| 14 | INC− | Inverting input of Amp C - complements Pin 13; supports unity-gain follower or summing configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +5V/0V only - eliminates need for split supplies in portable data loggers and handheld meters. |
| Rail-to-ground input range | Input common-mode extends to V− (0V) - enables direct interfacing with grounded sensors like RTDs and bridge outputs. |
| Ground-swinging output | Outputs sink to within 15mV of V− - permits full-scale 0–5V ADC interfacing without level-shifting components. |
| Low 1/f noise | 0.55 µVp-p (0.1–10Hz) - minimizes drift-induced errors in slow-sampling thermocouple and strain applications. |
| High open-loop gain | 1.5 million min (5mA load) - ensures <0.001% gain error in closed-loop configurations up to 100× gain. |

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 | Identical pinout and 14-pin PDIP package; 50µV max VOS, 0.6µV/°C TCVOS, 375µA supply current. | Same single-supply ground-swing capability but higher drift limits use in <50°C ambient-only applications. | Select when long-term calibration stability is less critical than immediate availability and known LT1014 footprint compatibility. |
| OP4177ARZ | 14-pin SOIC package only; 25µV max VOS, 0.6µV/°C TCVOS, 500µA supply current, rail-to-rail output. | Not pin-compatible; requires PCB redesign; superior offset but higher quiescent current reduces battery life. | Select for new designs prioritizing lowest offset and rail-to-rail output, accepting SOIC layout change and higher power draw. |
Compared with LT1014CN#PBF, MXL1014CN+ offers lower drift and supply current; compared with OP4177ARZ, it provides proven PDIP reliability and lower power at the cost of slightly higher offset and non-rail-to-rail output - making it optimal for legacy-replacement and battery-constrained applications.

FAQ
Is MXL1014CN+ recommended for new designs?
No - Maxim explicitly states MXL1014CN+ is "Not Recommended for New Designs" due to discontinuation of its wafer fabrication process. It remains available for existing designs and legacy replacements, but new projects should evaluate alternatives like LT1014CN#PBF or OP4177ARZ with engineering validation.
What is the operating temperature range of MXL1014CN+?
The MXL1014CN+ is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in its part number. This commercial-grade rating aligns with standard industrial control panels and portable test equipment environments where extended temperature ranges are not required.
Does MXL1014CN+ support true single-supply operation with ground-referenced inputs and outputs?
Yes - the MXL1014CN+ accepts input voltages down to V− (0V) and swings its outputs to within 15mV of V− under no-load conditions. This rail-to-ground behavior enables direct interfacing with grounded sensors and ADCs without level-shifting circuitry when powered from +5V/0V.
What is the maximum output current capability of MXL1014CN+?
The MXL1014CN+ can source and sink more than 20mA per amplifier, as confirmed in the General Description. This is sufficient to drive 4–20mA current loops directly or interface with moderate-impedance loads such as 600Ω transmission lines or LED indicators without external buffers.
How does MXL1014CN+ compare to LT1014 in terms of pin compatibility and performance?
The MXL1014CN+ is pin-compatible with LT1014 in 14-pin DIP packages and shares identical pin functions. It improves upon LT1014 with lower typical offset voltage (40µV vs. 50µV), lower drift (0.3µV/°C vs. 0.6µV/°C), and lower supply current (350µA vs. 375µA), making it a direct performance upgrade for existing LT1014 designs.
