Product details
Overview
LT1001CS8#PBF from Analog Devices (acquired Linear Technology) is a precision operational amplifier in an 8-pin SOIC package, featuring 60 µV max input offset voltage, 1.0 µV/°C max offset drift, and 110 dB min CMRR at 25°C. It delivers ±12.5 V output swing into 2 kΩ with 0.25 V/µs slew rate and operates from ±3 V to ±18 V supplies - ideal for high-accuracy thermocouple and strain gauge signal conditioning.
For engineers reviewing the LT1001CS8#PBF datasheet, LT1001CS8#PBF pinout, LT1001CS8#PBF application, or LT1001CS8#PBF equivalent, key selection criteria include guaranteed low-drift performance over 0°C to 70°C, low 0.3 µVP-P (0.1–10 Hz) noise, and compatibility with legacy OP-07/OP-05 sockets without external compensation.
Technical Context
The LT1001CS8#PBF employs a proprietary bipolar process optimized for tight distribution of input offset voltage - 95% of units exhibit <50 µV offset - enabling stringent commercial-grade specifications without binning. Its architecture integrates matched input transistors and laser-trimmed thin-film resistors to guarantee stability across temperature and time.
It supports unity-gain stable operation with no external compensation required, features internal frequency compensation, and maintains >60° phase margin from –55°C to 125°C. The device achieves 0.4 MHz gain-bandwidth product while dissipating only 48–80 mW, nearly half that of comparable precision op amps like the OP-07.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60 µV max (guaranteed at 25°C; enables ≤0.001% full-scale error in 20 V-range voltage followers) |
| Offset Drift | 1.0 µV/°C max (ensures <70 µV total drift over 0°C to 70°C operating range) |
| CMRR | 110 dB min (rejects ≥100,000:1 common-mode interference at DC, critical for bridge sensor interfaces) |
| Slew Rate | 0.25 V/µs (supports 10 kHz full-power bandwidth at ±10 V output swing) |
| Supply Range | ±3 V to ±18 V (enables direct use with standard dual-rail lab supplies and battery-powered systems down to ±1.2 V with gain ≥2) |
| Input Noise | 0.3 µVP-P (0.1–10 Hz); 9.8 nV/√Hz @ 1 kHz (preserves SNR in µV-level sensor amplification) |
| Output Drive | ±12.5 V into 2 kΩ (delivers 6.25 mA load current while maintaining linearity and low distortion) |
Pinout & Package
LT1001CS8#PBF is housed in an 8-pin plastic SOIC (Small Outline Integrated Circuit) package, 0.150-inch body width, with gull-wing leads and JEDEC MS-012AC compliant footprint. Thermal resistance θJA = 150°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (–) | Connects to wiper of 10 kΩ potentiometer between Pins 5 and 8 for manual VOS trimming; does not degrade thermal drift when adjusted |
| 2 | Inverting Input (–IN) | Differential input node with 30 MΩ min differential input resistance; sensitive to thermoelectric EMFs - requires matched, low-thermoelectric PCB traces |
| 3 | Non-Inverting Input (+IN) | Differential input node; bias current ±0.7 nA max ensures <1 µV error across 1 MΩ source impedances |
| 4 | V– (Negative Supply) | Ground reference for negative rail; must be decoupled with 0.1 µF ceramic capacitor placed ≤5 mm from pin |
| 5 | Offset Null (+) | Connects to one end of nulling potentiometer; forms adjustable voltage divider with Pin 1 and Pin 8 to cancel input offset |
| 6 | Output | Class AB output stage capable of sourcing/sinking ≥10 mA; short-circuit protected with indefinite duration rating |
| 7 | V+ (Positive Supply) | Power supply input; PSRR ≥106 dB minimizes ripple coupling into signal path; requires local 0.1 µF + 10 µF decoupling |
| 8 | NC (No Connect) | Internally unconnected; must remain floating - no routing or grounding permitted |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Low Offset Drift | 1.0 µV/°C max over 0°C to 70°C - enables stable calibration in industrial temperature environments without active recalibration |
| Low 0.1–10 Hz Noise | 0.3 µVP-P - preserves resolution in DC-coupled microvolt-level measurements such as RTD and thermopile outputs |
| High CMRR at DC | 110 dB min - rejects power-line hum and ground-loop interference in single-ended sensor interfaces referenced to noisy system grounds |
| Unity-Gain Stable | No external compensation required - simplifies layout and eliminates risk of instability from stray capacitance in compact PCB designs |
| Wide Supply Range | Operates from ±3 V to ±18 V - supports both low-voltage portable instrumentation and high-dynamic-range industrial signal chains |
Applications
| Thermocouple Amplifier | Strain Gauge Signal Conditioner |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP-07CP | Higher 60 µV VOS (same max), but 0.2 µV/°C drift (superior); 0.3 V/µs slew rate; requires external nulling pins (6 & 7) | Preferred in ultra-low-drift lab equipment where long-term calibration stability outweighs speed; not socket-compatible with LT1001CS8#PBF pinout | Select OP-07CP only if drift <0.3 µV/°C is mandatory and board layout allows dedicated nulling circuitry. |
| AD8628ARZ | Zero-drift auto-zero architecture; 1 µV VOS max, 0.002 µV/°C drift; 2.5 V/µs slew; rail-to-rail output; 5 V single-supply only | Better for battery-powered µV-signal apps needing zero-drift over time, but incompatible with ±15 V systems and introduces 10 kHz switching artifacts | Choose AD8628ARZ for portable, low-voltage, ultra-stable DC apps; avoid in ±15 V industrial systems or noise-sensitive audio paths. |
Compared with OP-07CP and AD8628ARZ, the LT1001CS8#PBF offers best-in-class balance of guaranteed commercial-grade precision, wide dual-supply operation, unity-gain stability, and legacy socket compatibility - making it optimal for retrofitting and cost-sensitive high-accuracy analog signal chains.

FAQ
What is the maximum operating temperature range for the LT1001CS8#PBF?
The LT1001CS8#PBF is specified for operation from 0°C to 70°C (commercial grade). While absolute maximum junction temperature is 150°C, its electrical characteristics - including 60 µV max input offset voltage and 1.0 µV/°C max drift - are guaranteed only within this 0°C to 70°C ambient range. For extended temperature operation, consider the LT1001AMH/883 variant.
Can the LT1001CS8#PBF replace an OP-07 in an existing design without layout changes?
Yes - the LT1001CS8#PBF is pin-compatible with the OP-07 in 8-pin DIP and SOIC packages and requires no external compensation. However, note that Pin 8 is NC (no connect) on LT1001CS8#PBF versus the OP-07's Pin 8 (offset null), so existing nulling circuitry must be disconnected or repurposed. Full functional equivalence is confirmed per Linear Technology Application Note 1001 F01.
Does the LT1001CS8#PBF require external capacitors for stability?
No. The LT1001CS8#PBF is internally compensated for unity-gain stability and remains stable driving capacitive loads up to 1000 pF in voltage-follower configuration. Per Figure 1001 G20 in the datasheet, overshoot stays below 20% with 1000 pF load. Local 0.1 µF ceramic decoupling at Pins 4 and 7 is mandatory, but no external phase-compensation network is needed.
How is input offset voltage trimmed in the LT1001CS8#PBF?
The LT1001CS8#PBF uses wafer-level laser trimming of input transistor matching and thin-film resistors to achieve its guaranteed 60 µV max offset. External nulling via Pins 1 and 5 (with 10 kΩ pot to Pin 8) is optional and adds ≤1 µV/°C drift penalty if adjusted away from zero. Trim range is ±2.5 mV, sufficient for final system calibration.
What is the typical 0.1 Hz to 10 Hz input noise voltage of the LT1001CS8#PBF?
The LT1001CS8#PBF delivers 0.3 µVP-P typical input-referred noise in the 0.1 Hz to 10 Hz band, measured per Figure 1001 G04. This value is guaranteed ≤0.6 µVP-P across all units. Its 4 Hz 1/f noise corner enables superior low-frequency SNR versus general-purpose op amps - critical for DC-coupled sensor interfaces.
