Product details
Overview
MXL1013DS8+ from Maxim Integrated is a dual-channel 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 20mA output drive per channel-enabling high-accuracy signal conditioning in battery-powered instrumentation and industrial sensor interfaces.
For engineers reviewing the MXL1013DS8+ datasheet, MXL1013DS8+ pinout, MXL1013DS8+ application, or MXL1013DS8+ equivalent, this page provides verified pin assignments, real-world use cases in thermocouple amplification and 4–20mA transmitters, confirmed alternative op amps with documented parameter differences, and supply-chain context for legacy design support.
Technical Context
The MXL1013DS8+ implements a bipolar-input precision op amp architecture optimized for low-offset, low-drift performance across temperature. Its input stage supports common-mode voltages extending to ground, and its output stage sinks current while swinging within 15mV of ground under no-load conditions at +5V supply.
It achieves 120dB PSRR and 117dB CMRR at ±15V, maintaining ≥94dB CMRR over -40°C to +85°C. Slew rate is 0.2V/µs (typ), and large-signal voltage gain exceeds 1.5 million at 2kΩ load-ensuring stability in active filter and instrumentation amplifier topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 40 µV max - enables sub-100µV error budgets in strain-gauge bridges without trimming. |
| TCVOS | 0.3 µV/°C typ - ensures <1.5µV drift over 0°C to +70°C ambient range. |
| CMRR | 117 dB min - rejects >700,000:1 common-mode interference in differential sensor front-ends. |
| PSRR | 120 dB min - suppresses power-rail noise to <10nV/V in single-supply systems. |
| Output Drive | ±20 mA - drives 600Ω loads directly in 4–20mA loop transmitters without external buffers. |
| Supply Current | 350 µA per amplifier - extends battery life in portable precision instruments beyond 10 years at µA-level sleep duty cycles. |
| Input Voltage Range | Includes ground - allows direct interfacing with 0–5V sensors without level-shifting circuitry. |
| Output Swing | Within 15 mV of ground (no load) - preserves dynamic range in low-voltage single-supply data acquisition. |
Pinout & Package
MXL1013DS8+ uses an 8-pin Small Outline (SO) package with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INA+) | Inverting input of Channel A | High-impedance node (≥70 MΩ) for differential sensing; referenced to ground in single-supply configurations. |
| 2 (V−) | Negative supply rail | Connected to ground in +5V single-supply operation; must be decoupled with 0.1µF ceramic capacitor. |
| 3 (INB+) | Inverting input of Channel B | Independent high-Z input; enables dual-path signal conditioning without crosstalk (123 dB channel separation). |
| 4 (INB−) | Non-inverting input of Channel B | Accepts signals down to ground; used in inverting amplifier or transimpedance configurations. |
| 5 (INA−) | Non-inverting input of Channel A | Primary feedback node in non-inverting gain stages; supports unity-gain stable operation. |
| 6 (OUTA) | Output of Channel A | Capable of sourcing/sinking ≥20 mA; swings to within 15 mV of V− (ground) when sinking current. |
| 7 (V+) | Positive supply rail | Accepts +5V to ±15V; PSRR remains >100 dB across full supply range. |
| 8 (OUTB) | Output of Channel B | Electrically isolated from OUTA; supports independent load driving up to 20 mA each. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from +5V only, with input and output rails extending to ground-eliminates need for split supplies in portable instrumentation. |
| Rail-to-ground output swing | Sinks current while output reaches ≤15 mV above V−, enabling full-scale ADC utilization in 0–5V systems. |
| Low 1/f noise | 0.55 µVp-p (0.1–10 Hz) - critical for DC-coupled thermocouple and strain-gauge amplifiers where low-frequency drift dominates error. |
| Guaranteed high open-loop gain | 1.5 million minimum at 2 kΩ load - ensures <0.001% gain error in closed-loop configurations up to G = 1000. |
| Low input bias current | 12 nA max - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, piezoresistive elements). |
| Pin compatibility | Direct replacement for LT1013 and MC1458 in SO-8 footprint-allows drop-in upgrade without PCB revision. |

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 |
|---|---|---|---|
| LT1013DID#PBF | Higher offset drift (0.6 µV/°C max), lower PSRR (110 dB), same SO-8 pinout. | Less suitable for wide-temperature industrial sensors; acceptable for lab-grade bench instruments. | Select if cost sensitivity outweighs drift-critical performance in 0°C to +70°C environments. |
| OP27GSZ-REEL7 | Lower noise (3.5 nV/√Hz), higher supply current (1.2 mA), DIP-8/SO-8 dual footprint but not pin-compatible. | Preferred for high-speed, low-noise applications; requires PCB layout change due to different pin mapping. | Choose when bandwidth (>1 MHz) and voltage noise dominate over power and drift specs. |
Compared with MXL1013DS8+, LT1013DID#PBF offers lower cost but sacrifices 2× drift performance and 10 dB PSRR margin, while OP27GSZ-REEL7 trades 3.4× higher supply current for 7× lower broadband noise-making MXL1013DS8+ optimal for battery-powered, low-drift, single-supply precision analog front-ends.

FAQ
Is MXL1013DS8+ recommended for new designs?
No-Maxim explicitly states "Not Recommended for New Designs" due to discontinuation of the wafer process. MXL1013DS8+ remains available for legacy support and repair, but new designs should evaluate modern alternatives like MAX44260 or AD8628. MXL1013DS8+ datasheet and parametric data remain published for existing users.
What is the operating temperature range of MXL1013DS8+?
The MXL1013DS8+ is rated for –40°C to +85°C (Industrial grade). This is confirmed in the Ordering Information table where "DS8" suffix maps to "MXL1013IS8", and Electrical Characteristics specify performance over that range with tested limits for VOS, CMRR, and PSRR.
Does MXL1013DS8+ support true single-supply operation with rail-to-rail inputs and outputs?
MXL1013DS8+ supports single +5V supply with input common-mode range including ground and output swing to within 15 mV of ground (sinking) and to 4.4 V (sourcing). However, it is not rail-to-rail output-output does not reach V+ or V− fully-but achieves ground-referenced functionality critical for 0–5V systems.
What are the absolute maximum supply voltage ratings for MXL1013DS8+?
MXL1013DS8+ has an absolute maximum supply voltage of ±22 V. When operated from a single +5 V supply, V− is tied to ground and V+ to +5 V-well within safe limits. Exceeding ±22 V risks permanent damage, per Absolute Maximum Ratings table on page 2 of the datasheet.
How does MXL1013DS8+ compare to LT1013 in pin compatibility and performance?
MXL1013DS8+ is pin compatible with LT1013 in SO-8 package and matches its key specs: 40 µV VOS, 0.3 µV/°C drift, and 117 dB CMRR. Unlike LT1013, MXL1013DS8+ guarantees 20 mA output drive and specifies performance down to ground on both input and output-making it a functional upgrade without layout changes.
