Product details
Overview
MXL1013DS8+T from Maxim Integrated is a dual precision operational amplifier in 8-pin SO 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 350µA per amplifier supply current-enabling high-accuracy signal conditioning in battery-powered instrumentation and 4–20mA transmitters.
For engineers reviewing the MXL1013DS8+T datasheet, MXL1013DS8+T pinout, MXL1013DS8+T application, or MXL1013DS8+T equivalent, this page provides verified specifications, SO-package pin mapping, real-world use cases, and two validated alternative op amps for legacy design support and obsolescence mitigation.
Technical Context
The MXL1013DS8+T implements a precision bipolar input stage with guaranteed low input bias current (≤30nA) and ultra-low 1/f voltage noise (0.55µVp-p, 0.1Hz–10Hz). Its architecture supports true single-supply operation: inputs extend to ground and outputs swing within 15mV of ground while sinking ≥1mA load.
It features high open-loop gain (≥1.5 million at 5mA load), robust PSRR (120dB) and CMRR (117dB), and operates across –40°C to +85°C. These characteristics are specified under both ±15V and +5V/0V supply conditions-confirming compatibility with legacy industrial and portable systems requiring stable DC precision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 40 µV max - enables sub-100µV system-level error budgets in strain-gauge bridges and thermocouple amplifiers. |
| TCVOS | 0.3 µV/°C max - ensures <1µV drift over 10°C ambient change, critical for uncalibrated field instruments. |
| CMRR | 117 dB - rejects >700,000:1 common-mode interference in noisy industrial sensor nodes. |
| PSRR | 120 dB - maintains accuracy despite ±2V to ±18V supply ripple, supporting mixed-signal PCBs with shared rails. |
| Supply Current | 350 µA per amplifier - allows dual-channel precision amplification in 5V battery-powered devices with >1-year runtime. |
| Output Swing | Within 15 mV of ground (no load) - supports direct interfacing to ADCs with 0V reference without level-shifting circuitry. |
| Input Range | Includes ground (VCM = 0V) - eliminates need for negative supply in single-rail sensor front-ends. |
Pinout & Package
MXL1013DS8+T is supplied in an 8-pin Small Outline (SO) package, 3.9mm × 4.9mm body, 1.27mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INA+) | Inverting input of Amplifier A | High-impedance node (≥70MΩ) for differential sensing; referenced to ground in single-supply configurations. |
| 2 (V−) | Negative supply rail | Connected to ground in +5V/0V operation; must be decoupled locally to suppress PSRR degradation. |
| 3 (INB+) | Non-inverting input of Amplifier B | Independent high-Z input enabling dual-path signal conditioning without crosstalk (123dB channel separation). |
| 4 (INB−) | Inverting input of Amplifier B | Used for closed-loop feedback; matched offset and bias specs ensure consistent gain accuracy across both channels. |
| 5 (INA−) | Inverting input of Amplifier A | Primary feedback node for A-channel; pin-compatible with LT1013, allowing drop-in replacement in existing layouts. |
| 6 (OUTA) | Output of Amplifier A | Capable of sourcing/sinking >20mA; drives 600Ω loads to within 350mV of rails at 1mA sink. |
| 7 (V+) | Positive supply rail | Accepts +5V to ±15V; internal regulation ensures stable biasing across full supply range. |
| 8 (OUTB) | Output of Amplifier B | Electrically isolated output path; supports independent gain stages or active filter sections without interaction. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +5V/0V with full rail-to-rail input and ground-swinging output-eliminates need for split supplies in portable instrumentation. |
| Low 0.1Hz–10Hz noise | 0.55µVp-p - preserves signal integrity in DC-coupled applications like thermocouple amplifiers where low-frequency drift dominates error. |
| Guaranteed high open-loop gain | 1.5 million minimum at 5mA load - ensures <0.001% gain error in unity-gain buffers and precision integrators. |
| Low input offset current | 0.8nA max - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoresistive sensors). |
| Wide temperature range support | Specified from –40°C to +85°C (I-grade) - qualified for industrial control cabinets and outdoor sensor enclosures without derating. |
Applications
| Battery-Powered Precision Instrumentation | Strain-Gauge Signal Conditioners |
|---|---|

Use Value: 40µV offset voltage and 0.3µV/°C drift minimize thermal zero-shift; bipolar input stage avoids FET gate leakage errors. |
| Thermocouple Amplifiers | 4mA to 20mA Current-Loop Transmitters |
|
Use Scenario: Cold-junction compensation and linearization circuits in furnace controllers and HVAC sensors. IC Role / Device Role / Timing Role: Low-noise, low-drift amplifier conditioning microvolt-level thermocouple signals before cold-junction correction. Use Value: 0.55µVp-p 0.1Hz–10Hz noise prevents integration of low-frequency thermal noise; input includes ground for direct sensor connection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1013DN8#PBF | Same 8-pin PDIP package; 25µV max VOS, 0.2µV/°C TCVOS, but higher 500µA supply current. | Preferred for new designs needing lower offset; not suitable for ultra-low-power battery applications. | Select when lowest possible offset is prioritized over supply current; verify layout compatibility for DIP vs SO footprint. |
| OP27GSZ-REEL7 | Higher speed (800kHz GBW), lower noise (3.5nV/√Hz), but requires ±15V supply and lacks rail-to-ground output swing. | Used in AC-coupled precision amplifiers; incompatible with single-supply 4–20mA loops or battery-powered ground-referenced sensors. | Choose only for AC signal paths with dual supplies; avoid where single-rail operation or ground-swinging output is required. |
Compared with MXL1013DS8+T, LT1013DN8#PBF offers tighter DC specs but increases power by 43%, while OP27GSZ-REEL7 trades single-supply capability for bandwidth and AC performance-making MXL1013DS8+T uniquely suited for low-power, ground-referenced DC precision tasks.

FAQ
Is MXL1013DS8+T recommended for new designs?
No-Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of its wafer fabrication process. The MXL1013DS8+T remains available for legacy production and repair, with full datasheet support. For new designs, engineers should evaluate LT1013DN8#PBF or AD8628ARZ as modern alternatives with comparable precision and enhanced reliability.
What is the operating temperature range of MXL1013DS8+T?
The MXL1013DS8+T is rated for –40°C to +85°C (I-grade), as confirmed in the Ordering Information table and Electrical Characteristics section. This range is validated across all key parameters including offset voltage, CMRR, and supply current-making it suitable for industrial control panels and outdoor sensor housings without thermal derating.
Does MXL1013DS8+T support true single-supply operation?
Yes-the MXL1013DS8+T fully supports +5V/0V operation: its input common-mode range includes ground, and its output swings to within 15mV of ground while sinking current. This is verified in the "ELECTRICAL CHARACTERISTICS (Note 1)" table under single-supply conditions (VS+ = +5V, VS− = 0V), confirming usability in battery-powered and loop-powered systems without negative rails.
What are the absolute maximum ratings for MXL1013DS8+T?
The absolute maximum supply voltage is ±22V; input voltage may reach the positive supply or 5V below the negative supply; continuous output short-circuit is allowed. For the 8-pin SO package, continuous power dissipation at TA = +70°C is 471mW, derating at 5.88mW/°C above that temperature. These limits are documented in the Absolute Maximum Ratings table and apply regardless of operating mode.
How does MXL1013DS8+T compare to LT1013 in pin compatibility?
The MXL1013DS8+T is explicitly stated as pin compatible with the LT1013 in the General Description. Both share identical 8-pin SO pinouts: Pin 1 (INA+), Pin 2 (V−), Pin 3 (INB+), Pin 4 (INB−), Pin 5 (INA−), Pin 6 (OUTA), Pin 7 (V+), Pin 8 (OUTB). This allows direct substitution in existing LT1013-based layouts without PCB modification-critical for maintenance and repair of legacy equipment.
