Product details
Overview
MXL1001CS8+ from Maxim Integrated is a precision operational amplifier in 8-pin SOIC package, pin-compatible with LT1001 and OP-07, delivering 60µV max input offset voltage, 110dB min CMRR, and 106dB min PSRR at ±15V supply for high-accuracy signal conditioning in thermocouple and strain gauge amplifiers.
For engineers reviewing the MXL1001CS8+ datasheet, MXL1001CS8+ pinout, MXL1001CS8+ application, or MXL1001CS8+ equivalent, key selection criteria include guaranteed low drift (1.0µV/°C max), low power dissipation (80mW max), input bias current ≤4nA, and compatibility with legacy precision op-amp footprints without layout change.
Technical Context
The MXL1001CS8+ employs zener-zap wafer-level trimming to achieve stable offset voltage and temperature coefficient, supporting closed-loop gains ≥+2 down to ±1.2V supplies. Its differential input stage enables ±13V input voltage range and ±13.5V output swing into 2kΩ load.
It features internal compensation for unity-gain stability and supports external offset nulling via dual VOS TRIM pins. Noise performance is specified at 0.3µVp-p (0.1–10Hz) and 9.8nV/√Hz (1kHz), with slew rate of 0.25V/µs and closed-loop bandwidth of 0.8MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60µV max - ensures minimal DC error in high-gain sensor interfaces without calibration |
| CMRR | 110dB min - rejects common-mode noise in low-level bridge measurements |
| PSRR | 106dB min - maintains accuracy under noisy or unregulated supply conditions |
| Input Bias Current | 4nA max - preserves signal integrity with high-impedance sources like thermocouples |
| Power Dissipation | 80mW max - reduces thermal drift and PCB heating vs. OP-07 (≈150mW) |
| Slew Rate | 0.25V/µs - supports stable amplification of low-frequency precision signals up to ~100kHz |
| Noise (0.1–10Hz) | 0.3µVp-p - enables resolution of sub-microvolt signals in data acquisition |
Pinout & Package
MXL1001CS8+ uses an 8-pin SOIC (Small Outline Integrated Circuit) package with standard SO-8 footprint and gull-wing leads. Thermal pad not present; JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOS TRIM | Connects to wiper of 10kΩ potentiometer for manual offset nulling |
| 2 | -IN | Inverting input - accepts feedback network or sensor signal reference |
| 3 | +IN | Non-inverting input - connects directly to high-impedance sensor outputs |
| 4 | V- | Negative supply rail - substrate tied internally to this pin |
| 5 | N.C. | No connection - electrically isolated; must remain floating |
| 6 | VOUT | Amplified output - drives loads ≥2kΩ with ±13.5V swing at ±15V supply |
| 7 | V+ | Positive supply rail - supports ±3V to ±18V dual-supply operation |
| 8 | VOS TRIM | Second trim terminal - completes nulling circuit with Pin 1 and potentiometer |
Key Features
| Feature | Design Value |
|---|---|
| Zener-zap trimmed offset | Enables 60µV max VOS without post-package adjustment; eliminates need for external nulling in many designs |
| Dual VOS TRIM pins | Supports precise external nulling with <1µV/°C added drift when adjusted to 300µV |
| Wide supply range | Operates from ±1.2V to ±18V - allows use with two NiCd cells or industrial ±15V rails |
| Low warm-up drift | Halved power dissipation vs. OP-07 reduces thermal gradient-induced offset drift during system startup |
| Pin compatibility | Direct drop-in replacement for LT1001, OP-07, OP-05, 725, 108A, and 101A - no PCB redesign required |
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), 0.6µV/°C drift, 120dB CMRR - tighter specs but higher cost | Better long-term stability for metrology-grade instruments; requires same SO-8 footprint | Select when <25µV VOS and <0.6µV/°C drift are mandatory; verify supply current (1.2mA vs. MXL1001CS8+'s 0.9mA) |
| OP07CP | 8-pin PDIP only; 75µV max VOS, 110dB CMRR, 100dB PSRR - wider VOS distribution, no SOIC option | Limited to through-hole assembly; higher power (150mW) increases thermal drift risk | Choose only for legacy DIP-based repairs; avoid for new SOIC designs due to packaging mismatch |
Compared with LT1001CN8#PBF and OP07CP, the MXL1001CS8+ offers optimal balance of SOIC availability, 60µV VOS, 80mW dissipation, and guaranteed 110dB CMRR - making it suitable for cost-sensitive, space-constrained industrial DAQ where moderate drift tolerance is acceptable.
Availability

Manufacturer
Maxim Integrated (now part of Analog Devices) designed high-performance analog and mixed-signal ICs for industrial, communications, and computing applications before its 2021 acquisition.
The MXL1001 series was developed as a cost-optimized, pin-compatible upgrade path for legacy precision op-amps like OP-07 and LT1001, targeting industrial sensor signal conditioning and data acquisition where low offset, low drift, and SOIC packaging were critical.
FAQ
Is MXL1001CS8+ recommended for new designs?
No, MXL1001CS8+ is Not Recommended for New Designs per Maxim's official notice. It was manufactured using a discontinued wafer process. While still available for existing designs and legacy repair, Aetrix recommends evaluating LT1001CN8#PBF or AD8628ARZ as modern alternatives. MXL1001CS8+ remains supported with full datasheet access and traceable inventory for continuity.
What is the operating temperature range of MXL1001CS8+?
The MXL1001CS8+ is rated for 0°C to +70°C commercial temperature operation. This is confirmed in the Ordering Information table and Electrical Characteristics section for the 'C' grade. It is not qualified for extended or military temperature ranges - those require MXL1001AMJ8 or MXL1001MH variants.
Does MXL1001CS8+ require external frequency compensation?
No, MXL1001CS8+ is internally compensated for unity-gain stability and does not require external capacitors. The datasheet explicitly states it can replace OP-07, OP-05, and 725 "with or without removal of external frequency compensation," confirming full internal compensation. This simplifies layout and improves reliability in precision circuits.
Can MXL1001CS8+ operate from a single supply?
MXL1001CS8+ is specified for dual-supply operation (±3V to ±18V). While it may function with asymmetric or single-ended supplies in limited cases, the datasheet provides no characterization for true single-supply use (e.g., 0V to +15V), and input/output voltage ranges assume symmetric rails. For single-supply applications, consider purpose-built rail-to-rail op-amps instead of MXL1001CS8+.
What is the purpose of Pin 5 (N.C.) on MXL1001CS8+?
Pin 5 on MXL1001CS8+ is designated N.C. (No Connection) and is electrically isolated within the die. It must remain unconnected on the PCB - neither grounded nor tied to any net. This isolation prevents parasitic coupling that could degrade CMRR or introduce noise, especially critical in low-level signal paths where MXL1001CS8+ is typically deployed.
