Product details
Overview
LT1001CN8#PBF from Analog Devices (acquired Linear Technology) is a precision operational amplifier in an 8-pin plastic DIP package, featuring 60 µV max input offset voltage, 1.0 µV/°C max offset drift, and 110 dB min common-mode rejection ratio at 25°C. It delivers ±12.5 V output swing into 2 kΩ load with 0.25 V/µs slew rate, enabling high-accuracy signal conditioning in low-drift sensor front-ends.
For engineers reviewing the LT1001CN8#PBF datasheet, LT1001CN8#PBF pinout, LT1001CN8#PBF application, or LT1001CN8#PBF equivalent, this page provides verified specifications, validated pin functions, confirmed use cases in platinum RTD and thermocouple amplification, and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The LT1001CN8#PBF employs laser-trimmed thin-film resistor networks to achieve guaranteed low offset voltage and drift across its 0°C to 125°C operating range. Its bipolar input stage delivers 4 nA max input bias current and 30 MΩ min differential input resistance, supporting high-impedance source interfacing without significant error.
It operates from ±3 V to ±18 V supplies, with 80 mW max power dissipation and 0.3 µVP-P (0.1–10 Hz) input noise. The device maintains stability in unity-gain configurations and supports closed-loop gains ≥ +2 at ±1.2 V supplies, making it suitable for battery-powered precision instrumentation.
Key Specifications

|---|---|
| Input Offset Voltage | 60 µV max - ensures ≤0.0003% full-scale error in 20 V-range voltage followers |
| Offset Voltage Drift | 1.0 µV/°C max - limits thermal-induced error to <10 µV over 10°C ambient shift |
| Common-Mode Rejection | 110 dB min - rejects >100,000:1 of common-mode interference in bridge sensor circuits |
| Slew Rate | 0.25 V/µs - supports ≤10 kHz full-power bandwidth for 10 VPP signals |
| Supply Voltage Range | ±3 V to ±18 V - enables operation from dual Ni-Cad (±1.2 V) up to industrial ±15 V rails |
| Output Swing | ±12.5 V into 2 kΩ - delivers 93% of rail-to-rail span for high dynamic range data acquisition |
| Input Bias Current | 4 nA max - introduces <40 µV error across 10 kΩ source impedance |
Pinout & Package
LT1001CN8#PBF uses an 8-pin plastic DIP (N8) package with 0.300-inch width, JEDEC MS-001 compliant footprint, and through-hole mounting. Pin 1 is offset corner, with pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Inverting Input (–IN) | Differential input node; high-impedance bipolar junction with 30 MΩ min resistance |
| 3 | Non-Inverting Input (+IN) | Differential input node; matched to Pin 2 for CMRR optimization |
| 4 | V– (Negative Supply) | Connects to negative rail; supports operation down to –18 V |
| 5 | Offset Adjust (+) | Connects to one end of nulling pot; forms adjustable voltage divider with Pin 1 |
| 6 | Output (OUT) | Class AB output stage capable of ±10 mA continuous drive into resistive loads |
| 7 | V+ (Positive Supply) | Connects to positive rail; supports operation up to +18 V |
| 8 | No Connect (NC) | Internally unconnected; must remain floating per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed offset | Guarantees 60 µV max VOS at 25°C without external nulling components |
| Low warm-up drift | Power dissipation halved vs legacy precision op amps, reducing thermal settling time |

IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with low-drift gain and offset correction. Use Value: Achieves ±0.025°C accuracy by limiting total worst-case error to 95 µV (LT1001CN8#PBF contributes <60 µV offset + <30 µV CMRR error). |

IC Role / Device Role / Timing Role: Low-noise, low-bias-current amplifier for microvolt-level thermoelectric signals. Use Value: 4 nA max input bias current prevents >0.1°C error from thermocouple series resistance; 0.3 µVP-P noise preserves signal integrity. |
| Strain Gauge Bridge Readout | High-Accuracy Data Acquisition |
|
Use Scenario: Wheatstone bridge excitation and differential amplification for load cell outputs (2–3 mV/V). IC Role / Device Role / Timing Role: Precision difference amplifier with matched input terminals and high CMRR. Use Value: 110 dB CMRR rejects bridge common-mode voltage shifts; 60 µV offset enables sub-0.1% full-scale resolution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP177GPZ | 25 µV max VOS, 0.1 µV/°C drift, 130 dB CMRR - tighter specs but higher cost and 1.2 mA supply current vs 0.8 mA | Better drift performance suits aerospace-grade calibration; not required for commercial-grade RTD systems | Select OP177GPZ only when <0.5 µV/°C drift is mandated; LT1001CN8#PBF offers optimal cost/performance for industrial sensors |
| AD8628ARZ | 10 µV max VOS, rail-to-rail output, 1.5 mA supply current - CMOS input (0.1 pA bias) but lower PSRR (100 dB) | Superior for ultra-high-impedance pH electrodes; unsuitable for ±15 V industrial supplies due to 5.5 V max rating | Choose AD8628ARZ for battery-powered portable instruments with single 3.3 V supply; LT1001CN8#PBF remains preferred for dual-supply industrial DAQ |
Compared with OP177GPZ and AD8628ARZ, the LT1001CN8#PBF uniquely balances low-cost manufacturability, wide ±18 V supply tolerance, and guaranteed 60 µV offset in a through-hole DIP package-making it the most practical choice for cost-sensitive, high-reliability industrial sensor interfaces where extreme drift specs are unnecessary.

FAQ
What is the maximum operating temperature range for the LT1001CN8#PBF?
The LT1001CN8#PBF is rated for operation from 0°C to 125°C ambient temperature, with guaranteed performance across this full range for parameters including input offset voltage, drift, CMRR, and PSRR. This makes the LT1001CN8#PBF suitable for industrial environments where enclosure temperatures may exceed standard commercial limits.
Can the LT1001CN8#PBF replace an OP-07 in existing designs?
Yes-the LT1001CN8#PBF is pin-compatible with the OP-07 in 8-pin DIP sockets and requires no external compensation. Its lower 60 µV max offset and 1.0 µV/°C drift improve accuracy over the OP-07's typical 25 µV and 0.6 µV/°C, while maintaining identical gain-bandwidth (0.8 MHz) and slew rate (0.25 V/µs) performance.
Does the LT1001CN8#PBF require external nulling components?
No-offset voltage is laser-trimmed at wafer test, guaranteeing ≤60 µV without nulling. However, Pins 1 and 5 support optional 10 kΩ potentiometer adjustment for applications demanding <10 µV residual offset; trimming adds only 1 µV/°C drift penalty if set to 300 µV.
What is the minimum supply voltage for the LT1001CN8#PBF?
The LT1001CN8#PBF operates down to ±1.2 V (2.4 V total), sufficient for two-series Ni-Cad cells. At this voltage, it remains stable only in closed-loop gains ≥ +2 (non-inverting) or ≥ –1 (inverting); unity-gain stability requires ≥ ±3 V supplies per the datasheet.
How does the LT1001CN8#PBF handle capacitive loads?
The LT1001CN8#PBF drives up to 1000 pF capacitive loads with <20% overshoot in small-signal transient response. For larger loads, an isolation resistor (e.g., 100 Ω) between output and capacitance restores stability-verified in Figure 1001 G20 of the official datasheet.
