Product details
Overview
MXL1001CN8 from Maxim Integrated is a precision operational amplifier in 8-pin plastic DIP package, pin-compatible with LT1001 and OP-07, delivering 60µV max input offset voltage, 110dB min CMRR, and 106dB min PSRR at ±15V supply. It serves as a low-drift, low-power signal conditioning front-end for thermocouple amplifiers and high-accuracy data acquisition systems.
For engineers reviewing the MXL1001CN8 datasheet, MXL1001CN8 pinout, MXL1001CN8 application, or MXL1001CN8 equivalent, key selection considerations include guaranteed offset voltage drift (1.0µV/°C max), low 80mW power dissipation, 0.3µVp-p 0.1Hz–10Hz noise, and compatibility with legacy precision op-amp footprints requiring minimal layout change.
Technical Context
The MXL1001CN8 implements a bipolar input stage with zener-zap trimmed offset nulling, enabling stable DC performance across 0°C to +70°C. Its architecture supports closed-loop gains ≥+2 down to ±1.2V supplies while maintaining stability without external compensation.
It features dual VOS TRIM pins for external offset adjustment with ≤1µV/°C added drift when trimmed to 300µV, and substrate tied to V− for improved thermal coupling-critical for low-drift thermocouple interface designs where thermal gradients dominate error sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60µV max - enables sub-100µV system-level offset in single-stage amplification of µV-level thermocouple outputs |
| Offset Drift | 1.0µV/°C max - ensures <10µV total drift over 10°C ambient variation in lab-grade instrumentation |
| CMRR | 110dB min - rejects >100k:1 common-mode interference in bridge sensor interfaces |
| PSRR | 106dB min - maintains accuracy despite ±100mV ripple on ±15V rails in industrial power supplies |
| Power Dissipation | 80mW max - reduces warm-up drift and allows dense PCB placement without forced airflow |
| 0.1Hz–10Hz Noise | 0.3µVp-p - preserves resolution in 16-bit+ data acquisition sampling below 10Hz |
| Supply Range | ±3V to ±18V - supports operation from dual NiCd batteries (±2.4V) up to industrial ±15V rails |
Pinout & Package
MXL1001CN8 uses an 8-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and standard through-hole footprint. Pin 1 is VOS TRIM (left top), pin 2 is V+, pin 3 is VOUT, pin 4 is N.C., pin 5 is V−, pin 6 is +IN, pin 7 is −IN, pin 8 is VOS TRIM (right top).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | VOS TRIM | Connects to external 10kΩ potentiometer wiper; enables fine offset nulling without degrading temperature drift beyond (VOS/300) µV/°C |
| 2 | V+ | Positive supply rail input - must be decoupled within 1cm of pin to maintain PSRR and stability |
| 3 | VOUT | Amplifier output - drives ≥2kΩ loads directly; slew rate limits full-scale settling to ≥4ms for 20V step |
| 4 | N.C. | No internal connection - leave unconnected; no routing or grounding required |
| 5 | V− | Negative supply rail input - substrate tied internally to this pin for thermal symmetry in low-drift applications |
| 6 | +IN | Non-inverting input - high-impedance (≥30MΩ) node; sensitive to leakage currents and thermal EMFs |
| 7 | −IN | Inverting input - matched to +IN for optimal CMRR; requires symmetrical PCB layout to preserve rejection |
Key Features
| Feature | Design Value |
|---|---|
| Zener-zap trimmed offset | Enables factory-guaranteed 60µV max VOS without post-package trimming, reducing test cost and improving batch consistency |
| Dual VOS TRIM terminals | Allows external nulling with predictable drift penalty (≤1µV/°C per 300µV adjusted), supporting field calibration in deployed instruments |
| Substrate-to-V− connection | Minimizes thermal gradient-induced offset drift by equalizing die and leadframe temperature reference points |
| Stable at ±1.2V supply | Permits battery-powered portable sensors using two NiCd cells while maintaining closed-loop gain ≥+2 |
| Pin-compatibility with OP-07/LT1001 | Enables drop-in replacement in legacy designs without PCB rework, preserving existing compensation and nulling networks |
Applications
| Thermocouple Amplifiers | Strain Gauge Amplifiers |

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 (C grade), but 125mW max PD and higher 0.6µVp-p noise | Better initial offset but higher self-heating drift; less suitable for thermally isolated PCB sections | Prefer when absolute lowest initial VOS is critical and thermal management is robust |
| OP07CP | Same DIP-8 footprint, 30µV max VOS, but 100mW max PD and no VOS TRIM pins | Lacks external nulling capability; requires factory-trimmed boards or laser trimming | Choose when board-level calibration is impractical and production volume justifies tighter VOS screening |
Compared with LT1001CN8#PBF and OP07CP, the MXL1001CN8 offers superior power efficiency (80mW vs ≥100mW) and field-adjustable offset via dual trim pins-critical for recalibration in field-deployed instrumentation where thermal gradients vary unpredictably.

Manufacturer
Maxim Integrated (now part of Analog Devices) designed high-performance analog and mixed-signal ICs for industrial, medical, and communications applications before its 2021 acquisition.
The MXL1001 series was developed as a pin-compatible, lower-power upgrade path for legacy precision op-amps like OP-07 and LT1001-targeting instrumentation, sensor signal chains, and metrology equipment demanding long-term DC stability.
FAQ
Is MXL1001CN8 still recommended for new designs?
No. Maxim explicitly states MXL1001CN8 is "Not Recommended for New Designs" due to discontinuation of its wafer fabrication process. It remains available for existing users and legacy repair, but designers should evaluate MXL1001CN8 alternatives such as LT1001CN8#PBF or OP07CP for new projects requiring long-term supply assurance.
What does the "N8" suffix indicate in MXL1001CN8?
The "N8" suffix denotes an 8-pin plastic DIP package with commercial temperature range (0°C to +70°C). This matches the MXL1001C grade's 60µV max input offset voltage and 1.0µV/°C max drift specification. The "N" identifies the plastic DIP body, and "8" confirms the pin count-distinct from SO-8 (S8) or CERDIP-8 (J8) variants.
Can MXL1001CN8 replace OP-07 in existing circuits without modification?
Yes. MXL1001CN8 is pin-compatible with OP-07 and requires no PCB changes. Its lower 80mW power dissipation reduces warm-up drift, and identical pin functions-including dual VOS TRIM-allow reuse of existing nulling networks. However, verify stability with original compensation components, as bandwidth and slew rate differ slightly.
What is the purpose of the two VOS TRIM pins on MXL1001CN8?
The two VOS TRIM pins (pins 1 and 8) connect to opposite ends of an external potentiometer, enabling precise manual or automated offset nulling. Adjusting VOS introduces predictable drift: (VOS/300) µV/°C. For example, trimming to 300µV adds ≤1µV/°C drift-providing field recalibration capability unmatched by single-trim op-amps like OP07CP.
How does MXL1001CN8 achieve lower power dissipation than OP-07?
MXL1001CN8 achieves ~50% lower power dissipation (80mW vs OP-07's ~150mW) through optimized bipolar process design and reduced quiescent current-without sacrificing noise (0.3µVp-p) or speed (0.25V/µs slew rate). This cuts self-heating, decreasing warm-up drift and enabling denser layouts in space-constrained instrumentation.
