Analog Devices Inc./Maxim Integrated MXL1013CN8+

Overview

MXL1013CN8+ from Maxim Integrated is a dual precision operational amplifier designed for low-power, single-supply instrumentation applications. It features 40µV typical input offset voltage, 0.3µV/°C drift, 117dB CMRR, and rail-to-ground output swing with ±20mA drive capability. Used in strain-gauge signal conditioners and 4–20mA current-loop transmitters where precision and ground-sensing are critical.

For engineers reviewing the MXL1013CN8+ datasheet, MXL1013CN8+ pinout, MXL1013CN8+ application, or MXL1013CN8+ equivalent, this page delivers verified electrical specs, SO-8 package details, real-world use cases, and validated alternative op amps - all grounded in Maxim's official 19-0133 Rev. 3 documentation and ordering data.

Technical Context

The MXL1013CN8+ employs laser-trimmed thin-film resistor networks to achieve precision DC performance, including guaranteed 150µV max VOS over temperature and 2µV/°C max TCVOS. Its input stage uses matched PNP transistors enabling rail-to-ground common-mode input range and low input bias current (12–30nA).

Output stage design supports true single-supply operation: outputs swing within 15mV of ground while sinking 1mA, and to within 0.6V of V+ while sourcing 20mA. PSRR (120dB) and CMRR (117dB) remain stable across ±2V to ±18V supply ranges and up to 100kHz.

FAQ

Is MXL1013CN8+ recommended for new designs?

No - Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of its wafer fabrication process. The MXL1013CN8+ remains available for legacy support and existing production, with datasheet 19-0133 Rev. 3 still published for design validation and replacement planning. Engineers should evaluate LT1013DN8#PBF or AD8628ARZ as modern alternatives before committing to new schematics.

What is the operating temperature range of MXL1013CN8+?

The MXL1013CN8+ is rated for 0°C to +70°C ambient operation, as confirmed by its ordering suffix 'C' and the 'MXL1013CN8' entry in the official ordering table. Electrical characteristics are fully specified across this range, including guaranteed 150µV max input offset voltage and 2µV/°C max drift - critical for commercial-grade instrumentation.

Does MXL1013CN8+ support true single-supply operation with ground-referenced inputs and outputs?

Yes - the MXL1013CN8+ is explicitly characterized for +5V/0V operation. Its input common-mode range extends to V− (ground), and outputs swing to within 15mV of ground while sinking 1mA. This enables direct interfacing with 0V-referenced sensors (e.g., thermocouples) and driving ground-return loads (e.g., 4–20mA loop receivers) without negative supplies or level-shifting circuitry.

How does MXL1013CN8+ compare to LM158 in terms of precision performance?

The MXL1013CN8+ significantly upgrades LM158: it delivers 40µV typical offset voltage versus LM158's 2000µV, 0.3µV/°C drift versus 7µV/°C, and 117dB CMRR versus 85dB. These improvements enable MXL1013CN8+ to replace LM158 in applications requiring <100µV system error budgets - such as medical sensor front-ends or high-resolution data acquisition - without changing PCB layout (pin-compatible in SO-8).

What are the absolute maximum ratings for MXL1013CN8+ supply voltage?

The MXL1013CN8+ has an absolute maximum supply voltage rating of ±22V, meaning the difference between V+ and V− must not exceed 44V. For single-supply use, V+ may be up to +22V with V− at 0V; for dual-supply, ±15V is the standard operating condition. Exceeding ±22V risks permanent damage, per Maxim's Absolute Maximum Ratings table in datasheet 19-0133.
