Product details
Overview
MXL1001CN8+ from Maxim Integrated is a precision operational amplifier in an 8-pin plastic DIP package, pin-compatible with LT1001 and OP-07. It delivers 60µV max input offset voltage, 110dB min CMRR, and 106dB min PSRR at ±15V supply, targeting low-drift, low-noise signal conditioning in thermocouple and strain gauge amplifiers.
For engineers reviewing the MXL1001CN8+ datasheet, MXL1001CN8+ pinout, MXL1001CN8+ application, or MXL1001CN8+ equivalent, key selection criteria include guaranteed offset voltage drift (1.0µV/°C max), low power dissipation (80mW max), and compatibility with legacy precision op-amp footprints requiring no PCB redesign.
Technical Context
The MXL1001CN8+ employs zener-zap wafer-level trimming to achieve stable input offset voltage and temperature coefficient. Its architecture supports closed-loop gains ≥+2 down to ±1.2V supplies, with internal compensation eliminating need for external frequency compensation in most configurations.
It features dual VOS TRIM pins enabling post-assembly offset nulling via 10kΩ–20kΩ potentiometer without degrading thermal drift performance. Input bias current remains below 4nA max across 0°C to +70°C, supporting high-impedance sensor interfaces without significant error contribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60µV max - ensures ≤0.006% gain error in 1V full-scale instrumentation amplifiers |
| Offset Drift | 1.0µV/°C max - limits thermal-induced error to <7µV over 70°C ambient range |
| CMRR | 110dB min - rejects >316k:1 common-mode interference in bridge sensor circuits |
| PSRR | 106dB min - suppresses supply ripple to <0.5µV/V at output under ±15V operation |
| Power Dissipation | 80mW max - enables use in thermally constrained enclosures without forced cooling |
| Noise (0.1–10Hz) | 0.3µVp-p - supports resolution of sub-10µV DC signals in data acquisition front-ends |
| Supply Range | ±3V to ±18V - operates from dual NiCd batteries (±1.2V) up to industrial rail voltages |
Pinout & Package
MXL1001CN8+ uses an 8-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin 1 is VOS TRIM (left top), pin 5 is +IN, pin 6 is -IN, pin 7 is VOUT, pin 8 is V+, pin 4 is V-, and pins 2 and 3 are unused (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | VOS TRIM | Connects to external 10kΩ potentiometer wiper for precision zero-adjust without affecting drift |
| 2, 3 | N.C. | No internal connection - must remain unconnected per datasheet; floating or grounded causes undefined behavior |
| 4 | V- | Negative supply terminal - substrate tied internally to this pin; requires low-impedance return path |
| 5 | +IN | Non-inverting input - high-impedance node (≥30MΩ) for reference or sensor excitation inputs |
| 6 | -IN | Inverting input - matched to +IN for common-mode rejection; sensitive to layout symmetry |
| 7 | VOUT | Amplified output - capable of ±13.5V swing into 2kΩ load at ±15V supply |
| 8 | V+ | Positive supply terminal - decoupling capacitor required within 1cm for stability |
Key Features
| Feature | Design Value |
|---|---|
| Zener-zap trimmed offset | Enables 60µV max VOS without post-package calibration, reducing test time and cost |
| Dual VOS TRIM terminals | Allows field-adjustable nulling with <1µV/°C added drift penalty - critical for long-term calibration stability |
| Low 80mW power dissipation | Reduces warm-up drift by ~50% vs OP-07, improving measurement repeatability in unregulated environments |
| Guaranteed 110dB CMRR | Maintains accuracy in noisy industrial settings where ground loops induce >100mV common-mode noise |
| Pin-compatible with OP-07/LT1001 | Enables drop-in replacement in existing designs without layout changes or signal path revalidation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1001CN8#PBF | Same pinout; 25µV max VOS, 0.6µV/°C drift, but 120mW dissipation and no VOS TRIM pins | Lacks external nulling capability; requires tighter board-level thermal management | Preferred when lower initial offset outweighs need for field calibration |
| OP07EP | Same pinout; 25µV max VOS, 0.3µV/°C drift, but 140mW dissipation and no guaranteed 0°C–70°C CMRR spec | Higher power draw increases warm-up drift; CMRR not characterized across full temp range | Selected for ultra-low drift where thermal stability dominates over power constraints |
Compared with LT1001CN8#PBF and OP07EP, MXL1001CN8+ offers unique balance: externally adjustable offset with minimal drift penalty, lower power than both alternatives, and full-temperature-range CMRR/PSRR guarantees - making it optimal for field-serviceable, battery-constrained, or thermally variable deployments.

FAQ
What is the operating temperature range for MXL1001CN8+?
The MXL1001CN8+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated across all key parameters including input offset voltage, CMRR, and PSRR. The device's 1.0µV/°C max offset drift ensures predictable performance within this envelope, and its plastic DIP package supports reliable long-term operation in non-military environments. MXL1001CN8+ does not support extended or military temperature grades.
Is MXL1001CN8+ pin-compatible with OP-07?
Yes, MXL1001CN8+ is fully pin-compatible with OP-07 in the 8-pin DIP package. Pin assignments for V+, V-, +IN, -IN, VOUT, and N.C. match exactly, allowing direct substitution without PCB modification. However, MXL1001CN8+ adds dual VOS TRIM pins (pins 1 and 8) not present on OP-07 - these must be left unconnected if retaining original nulling circuitry, or used for enhanced calibration if upgrading.
Does MXL1001CN8+ require external frequency compensation?
No, MXL1001CN8+ is internally compensated and stable at unity gain. Unlike earlier precision op-amps such as OP-05 or 725, it does not require external capacitors for stability in standard configurations. This simplifies design and eliminates component count in thermocouple or strain gauge amplifier circuits. The device maintains phase margin >45° across its full supply range (±3V to ±18V) and load conditions.
What is the maximum power dissipation of MXL1001CN8+?
The maximum power dissipation of MXL1001CN8+ is 80mW at 25°C ambient, derating linearly at 5.6mW/°C above +36°C due to its plastic DIP package. This value is measured under no-load conditions at ±15V supply. At lower supplies (e.g., ±5V), dissipation drops proportionally, enabling use in thermally isolated enclosures. MXL1001CN8+'s 80mW rating is approximately half that of OP-07, directly reducing warm-up drift.
Can MXL1001CN8+ operate from single-supply rails?
MXL1001CN8+ is specified only for dual-supply operation (±3V to ±18V) and lacks rail-to-rail input or output capability. Its input voltage range is limited to ±13V, and output swing reaches only ±13.5V into 2kΩ at ±15V. While it may function with asymmetric supplies (e.g., +15V/–5V), it is not characterized or guaranteed for true single-supply use. For single-rail applications, designers should consider purpose-built rail-to-rail op-amps instead of MXL1001CN8+.
