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, optimized for thermocouple amplification and low-level signal conditioning in industrial data acquisition systems.
For engineers reviewing the MXL1001CS8 datasheet, MXL1001CS8 pinout, MXL1001CS8 application, or MXL1001CS8 equivalent, key selection criteria include guaranteed offset voltage drift (1.0µV/°C max), low 80mW power dissipation, 0.3µVp-p 0.1Hz–10Hz noise, ±13V input voltage range, and compatibility with legacy precision op-amp footprints requiring minimal redesign effort.
Technical Context
The MXL1001CS8 employs zener-zap wafer-level trimming to achieve stable input offset voltage and temperature coefficient, enabling high-accuracy DC-coupled amplification without external nulling in many applications. Its architecture supports operation from ±3V to ±18V supplies and maintains stability at closed-loop gains ≥+2 down to ±1.2V dual supply.
It features differential input resistance of 100MΩ (typ), 0.25V/µs slew rate, and 0.4MHz closed-loop bandwidth-optimized for precision DC and low-frequency AC signal paths where long-term offset stability and common-mode rejection are critical over temperature and supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60µV max - enables ≤0.006% error in 1V full-scale measurement without calibration |
| CMRR | 110dB min - rejects >99.999% of common-mode interference in bridge sensor interfaces |
| PSRR | 106dB min - suppresses supply ripple to <0.5µV/V at output under varying rail conditions |
| Power Dissipation | 80mW max - reduces thermal drift and PCB heating vs. OP-07 (140mW typical) |
| Input Noise | 0.3µVp-p (0.1Hz–10Hz) - supports sub-µV resolution in thermocouple front-ends |
| Supply Range | ±3V to ±18V - operates from dual NiCd (±1.2V) up to industrial ±15V rails with gain ≥+2 |
| Offset Drift | 1.0µV/°C max - limits temperature-induced error to <7µV over 0°C to +70°C range |
Pinout & Package
MXL1001CS8 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC dimensions (4.9mm × 3.9mm × 1.75mm), gull-wing leads, and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | VOS TRIM | Offset null adjustment terminals - accept 10kΩ or 20kΩ potentiometer for fine-tuning; trimming to zero preserves 1.0µV/°C drift spec |
| 2 | -IN | Inverting input - high-impedance node (100MΩ typ) for feedback network connection |
| 3 | +IN | Non-inverting input - matched to -IN for optimal CMRR; requires symmetrical layout to minimize thermoelectric EMF |
| 4 | V- | Negative supply rail - substrate tied internally; must be lowest potential point in circuit |
| 5 | N.C. | No connect - electrically isolated; no routing or grounding required |
| 6 | VOUT | Amplifier output - capable of ±12.5V swing into 2kΩ load at ±15V supply |
| 7 | V+ | Positive supply rail - accepts up to ±22V absolute max; decoupling recommended within 1cm |
Key Features
| Feature | Design Value |
|---|---|
| Zener-zap trimmed offset | Eliminates need for external nulling in most 0°C–+70°C applications while preserving low drift |
| Low warm-up drift | Result of 80mW max dissipation - reduces settling time error in precision instrumentation startup |
| Wide supply range support | Operates down to ±1.2V with gain ≥+2 - enables battery-powered portable measurement devices |
| High open-loop gain | 500V/mV min - ensures <0.02% gain error in unity-gain buffer configurations |
| Thermocouple-optimized layout | Matched input pins and substrate-to-V− tie reduce thermal EMF errors in µV-level sensing |
Applications

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 8-pin DIP pinout; 25µV max VOS (C grade), higher 125dB CMRR, but 120mW dissipation | Preferred where lower offset and higher CMRR justify higher power and cost; not SOIC-compatible | Select LT1001CN8#PBF only if DIP packaging and tighter VOS spec are mandatory; MXL1001CS8 offers SOIC footprint advantage |
| OP07DP | SOIC-8 compatible; 75µV max VOS, 110dB CMRR, but 140mW dissipation and slower 0.3V/µs slew rate | Suitable for cost-sensitive upgrades of legacy OP-07 designs where board space is constrained | Choose OP07DP when direct OP-07 replacement is needed and 15µV higher VOS is acceptable; MXL1001CS8 provides better thermal performance |
Compared with LT1001CN8#PBF and OP07DP, MXL1001CS8 delivers superior power efficiency (80mW vs. ≥120mW), SOIC-8 compatibility absent in LT1001CN8, and lower offset drift than OP07DP-making it optimal for space-constrained, thermally sensitive precision analog front-ends.

Manufacturer

FAQ
Is MXL1001CS8 still recommended for new designs?
No. MXL1001CS8 is Not Recommended for New Designs per Maxim's official notice: the wafer process used is obsolete, and Maxim recommends evaluating replacements or second-source alternatives. MXL1001CS8 remains available for existing designs with documented continuity support, but new projects should consider modern precision op-amps with active lifecycle status and enhanced specs.
What is the maximum operating temperature range for MXL1001CS8?
The MXL1001CS8 is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is confirmed in the Ordering Information table and Electrical Characteristics section for the 'C' suffix variant. Operation outside this range may result in parametric degradation beyond datasheet guarantees, and the device is not tested or warranted for extended temperature use.
Does MXL1001CS8 require external offset nulling components?
MXL1001CS8 does not require external offset nulling in most applications: its 60µV max input offset voltage and 1.0µV/°C drift are achieved via zener-zap wafer-level trimming. However, Pin 1 and Pin 8 support optional 10kΩ/20kΩ potentiometer adjustment if sub-µV nulling is needed-trimming introduces predictable drift penalty (VOS/300 µV/°C).
How does MXL1001CS8 compare to OP-07 in power consumption?
MXL1001CS8 consumes significantly less power than OP-07: 80mW max versus ~140mW typical for OP-07 at ±15V. This 43% reduction lowers self-heating, decreases warm-up drift, and eases thermal management on dense PCBs-critical for multi-channel precision systems where thermal crosstalk affects measurement accuracy.
Can MXL1001CS8 operate from a single supply?
MXL1001CS8 is specified for dual-supply operation (±3V to ±18V) and is not characterized for true single-supply use. While it may function with asymmetric rails (e.g., +5V and ground), input common-mode range extends only to ±13V and output swing is rail-to-rail limited. For single-supply applications, purpose-built rail-to-rail I/O op-amps with verified 0V-input capability are strongly recommended instead of MXL1001CS8.
