Product details
Overview
LT1001ACN8#PBF from Analog Devices (formerly 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 CMRR at 0°C to 70°C. It delivers ±12.5 V output swing into 2 kΩ with 0.25 V/µs slew rate and supports ±3 V to ±18 V dual supply operation - ideal for high-accuracy thermocouple and strain gauge signal conditioning.
For engineers reviewing the LT1001ACN8#PBF datasheet, LT1001ACN8#PBF pinout, LT1001ACN8#PBF application, or LT1001ACN8#PBF equivalent, key selection criteria include guaranteed commercial-grade precision specs (offset, drift, CMRR), low 80 mW power dissipation, compatibility with OP-07/OP-05 sockets, and validated performance in platinum RTD linearization circuits requiring ±0.025°C accuracy.
Technical Context
The LT1001ACN8#PBF employs laser-trimmed thin-film resistor networks and proprietary dielectric isolation to achieve tight distribution of input offset voltage (≤60 µV) and low long-term stability drift (≤1.5 µV/month). Its bipolar input stage delivers 4 nA max bias current while maintaining 30 MΩ min differential input resistance.
Designed for unity-gain stable operation, it features internal compensation enabling use in voltage followers and instrumentation amplifiers without external components. The device meets MIL-STD-883 Class B screening for select variants and supports burn-in at 125°C - though the LT1001ACN8#PBF itself is rated for 0°C to 70°C operation per its commercial grade designation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 60 µV max - enables sub-100 µV system-level error in precision sensor interfaces without trimming. |
| Offset Voltage Drift | 1.0 µV/°C max - ensures ≤70 µV total drift over 0°C to 70°C operating range. |
| CMRR | 110 dB min - rejects common-mode noise up to 100,000:1, critical for bridge-based transducer measurements. |
| PSRR | 106 dB min - maintains accuracy despite ±1 V ripple on ±15 V supplies. |
| Slew Rate | 0.25 V/µs - supports 10 kHz full-power bandwidth with 10 Vpp output swing. |
| Supply Range | ±3 V to ±18 V - operates from two Ni-Cad cells (±1.2 V) in gain ≥+2 configurations. |
| Power Dissipation | 80 mW max - reduces self-heating-induced drift versus legacy precision op amps like OP-07. |
Pinout & Package
LT1001ACN8#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 pin 1–4 on left side and pin 5–8 on right side when viewed top-down with notch up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (–) | Connects to wiper of 10 kΩ potentiometer for manual VOS adjustment; does not degrade thermal drift when trimmed. |
| 2 | Inverting Input (–IN) | Differential input node; 4 nA max bias current enables high-impedance sensor interfacing. |
| 3 | Non-Inverting Input (+IN) | Differential input node; matched to Pin 2 for <1 µV input offset contribution from mismatch. |
| 4 | V– (Negative Supply) | Accepts –3 V to –18 V; supports rail-to-rail input common-mode range down to V– + 1.2 V. |
| 5 | Offset Null (+) | Second null terminal; used with Pin 1 to form balanced trim network per datasheet Figure F04. |
| 6 | Output (OUT) | Drives ≥10 mA load; delivers ±12.5 V swing into 2 kΩ with <0.001% worst-case follower error. |
| 7 | V+ (Positive Supply) | Accepts +3 V to +18 V; PSRR >106 dB ensures immunity to supply noise coupling. |
| 8 | No Connect (NC) | Internally unused; must remain unconnected to avoid parasitic coupling or latch-up risk. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed offset | Guarantees ≤60 µV max VOS without external trimming - eliminates production calibration steps in data acquisition modules. |
| Low warm-up drift | Power dissipation halved vs OP-07 reduces thermal gradient-induced offset shift during system stabilization. |
| Socket-compatible replacement | Direct drop-in for OP-07, OP-05, 725, 108A, and 101A sockets - enables precision upgrade without PCB redesign. |
| Guaranteed AC performance | 0.4 MHz GBW and 0.25 V/µs slew rate validated across temperature - ensures predictable settling in closed-loop filters. |
| High open-loop gain | 400 V/mV min at ±10 V output - maintains <0.025% linearity error in 100× gain instrumentation amplifier configurations. |
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 |
|---|---|---|---|
| OP-07CP | Higher 75 µV max VOS, 1.3 µV/°C drift, 120 dB CMRR; requires external nulling pins. | Legacy socket compatibility but larger warm-up drift and no guaranteed 0.1–10 Hz noise spec. | Select OP-07CP only if existing board layout mandates identical pinout and nulling configuration. |
| AD8628ARZ | Zero-drift auto-zero architecture; 1 µV max VOS, 0.002 µV/°C drift; CMOS input (1 pA bias). | Superior drift performance but higher 1.1 µVP-P noise and limited ±13.5 V output swing. | Choose AD8628ARZ for ultra-low-drift DC applications where 0.1–10 Hz noise <0.5 µVP-P is mandatory. |
Compared with OP-07CP and AD8628ARZ, the LT1001ACN8#PBF offers the best balance of guaranteed commercial-grade precision, proven socket compatibility, and low-noise bipolar performance - making it optimal for cost-sensitive industrial sensor signal chains where ±0.025°C or 0.05% accuracy is required without zero-drift complexity.

FAQ
What is the maximum operating temperature range for the LT1001ACN8#PBF?
The LT1001ACN8#PBF is specified for 0°C to 70°C ambient operation per its "C" grade designation. While absolute maximum junction temperature is 150°C, sustained operation above 70°C violates the guaranteed specifications - including 60 µV max offset voltage and 110 dB min CMRR - which are only validated within the commercial temperature range.
Can the LT1001ACN8#PBF replace an OP-07 in an existing design without modifications?
Yes, the LT1001ACN8#PBF is a direct socket-compatible replacement for OP-07 in 8-pin DIP layouts. Its pinout matches exactly (including offset null pins 1 and 5), and it operates with the same ±15 V supplies. No PCB changes are needed, though external nulling components may be omitted since LT1001ACN8#PBF's factory-trimmed offset eliminates their necessity.
Does the LT1001ACN8#PBF require external frequency compensation?
No, the LT1001ACN8#PBF is unity-gain stable and internally compensated. Unlike earlier precision op amps such as the 725, it does not require external capacitors for stability in voltage follower or gain-of-ten configurations - simplifying layout and eliminating compensation-related phase margin risks.
What is the typical 0.1 Hz to 10 Hz noise performance of the LT1001ACN8#PBF?
The LT1001ACN8#PBF delivers 0.3 µVP-P typical input-referred noise in the 0.1 Hz to 10 Hz band, as confirmed in the datasheet's "Typical Performance Characteristics" section (Figure G04). This low flicker noise supports high-resolution DC measurements where low-frequency interference dominates.
How is the offset voltage adjusted on the LT1001ACN8#PBF?
The LT1001ACN8#PBF provides dedicated offset null pins (1 and 5) for manual trimming using a 10 kΩ potentiometer. As documented in datasheet Figure F04, connecting the potentiometer wiper to Pin 1 and both ends to Pins 1 and 5 achieves ±2.5 mV adjustment range without degrading thermal drift performance - preserving the 1.0 µV/°C max specification.
