Product details
Overview
LT1013ACN8#PBF from Analog Devices (formerly Linear Technology) is a dual precision operational amplifier in an 8-pin PDIP package, featuring 150µV max input offset voltage, 0.35mA per amplifier supply current, and rail-to-rail output swing to ground on single 5V supply. It serves as a high-accuracy signal conditioner in thermocouple amplifiers and strain gauge interfaces.
For engineers reviewing the LT1013ACN8#PBF datasheet, LT1013ACN8#PBF pinout, LT1013ACN8#PBF application, or LT1013ACN8#PBF equivalent, key selection criteria include guaranteed 150µV max offset voltage, 2µV/°C max drift, 0.8nA max offset current, single-supply operation down to 3.4V, and compatibility with legacy MC1458/LM158 footprints.
Technical Context
The LT1013ACN8#PBF implements a precision bipolar input stage with all-NPN output stage, enabling true single-supply operation: input common-mode range extends to ground, and output sinks ≥1mA while swinging within 3.3mV of ground at 5V supply. Its phase reversal protection circuitry prevents output inversion when inputs go ≤–400mV below ground-unlike LM158 or OP-221.
It delivers 1.5 million min open-loop gain at ±15V (RL = 2kΩ), 117dB CMRR, and 120dB PSRR, with 0.55µVP-P 0.1Hz–10Hz noise. Guaranteed specs apply across 0°C to 70°C ambient, supporting industrial instrumentation where long-term stability and low thermal drift are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150µV max - ensures ≤0.015% error in 100mV full-scale sensor outputs without trimming |
| Offset Voltage Drift | 2µV/°C max - limits temperature-induced error to <10µV over 50°C ambient shift |
| Supply Current | 500µA max per amp - enables battery-powered designs with multi-year runtime at µA-level quiescent draw |
| Output Swing (Low) | 3.3mV above ground (RL = 600Ω) - supports true 0V-referenced ADC interfacing on 5V rails |
| Common-Mode Rejection | 117dB typical - rejects >99.999% of 10V common-mode interference in noisy industrial environments |
| Gain-Bandwidth Product | 1.2MHz - sufficient for DC–1kHz sensor conditioning with ≥60dB closed-loop gain margin |
| Input Offset Current | 0.8nA max - minimizes voltage error across high-impedance sources like thermistors or RTDs |
Pinout & Package
LT1013ACN8#PBF uses an 8-lead plastic DIP (PDIP) package with JEDEC MS-001 standard footprint, 0.3" wide body, and 0.1" lead pitch. Thermal resistance θJA = 130°C/W enables operation up to 70°C ambient without heatsinking.

| 2 | +IN A | Non-inverting input of Amplifier A - used for reference biasing or sensor excitation in bridge circuits |
| 3 | OUT A | Output of Amplifier A - drives loads up to 20mA while maintaining precision gain and linearity |
| 4 | V– | Negative supply rail - tied to ground in single-supply configurations; enables true 0V output swing |
| 5 | V+ | Positive supply rail - accepts 3.4V to ±22V; operates from single 5V or dual ±15V supplies |
| 6 | OUT B | Output of Amplifier B - independent channel for dual-path signal processing or redundancy |
| 7 | +IN B | Non-inverting input of Amplifier B - supports differential pair configuration with Amplifier A |
| 8 | –IN B | Inverting input of Amplifier B - used for feedback networks or active filter stages |

FAQ
What is the maximum input offset voltage specification for LT1013ACN8#PBF?
The LT1013ACN8#PBF has a guaranteed maximum input offset voltage of 150µV across its 0°C to 70°C operating temperature range. This specification is tested and ensured for every unit, enabling high-accuracy DC-coupled amplification without external nulling circuitry. The LT1013ACN8#PBF achieves this performance using a precision bipolar input stage with laser-trimmed resistor networks.
Does LT1013ACN8#PBF support true single-supply operation with output swing to ground?
Yes, the LT1013ACN8#PBF fully supports single-supply operation from 3.4V to 5V, with input common-mode range extending to ground and output capable of swinging to within 3.3mV of ground while sinking 1mA. This capability is enabled by its all-NPN output stage and internal phase reversal protection-critical for interfacing with 0V-referenced ADCs. The LT1013ACN8#PBF maintains these characteristics across its full temperature range.
What is the supply current consumption of LT1013ACN8#PBF per amplifier?
The LT1013ACN8#PBF consumes a maximum of 500µA per amplifier at 25°C, with typical consumption of 350µA under ±15V supply conditions. At 5V single supply, it draws 320µA typical per amplifier. This ultra-low quiescent current enables multi-year battery life in portable instrumentation. The LT1013ACN8#PBF maintains guaranteed performance across its entire 0°C to 70°C operating range without increase in supply current.
Is LT1013ACN8#PBF pin-compatible with legacy dual op amps like MC1458?
Yes, the LT1013ACN8#PBF uses the industry-standard 8-pin DIP pinout identical to MC1458, LM158, and OP-221-making it a direct drop-in upgrade. Pin 1 is –IN A, Pin 2 is +IN A, Pin 3 is OUT A, Pin 4 is V–, Pin 5 is V+, Pin 6 is OUT B, Pin 7 is +IN B, and Pin 8 is –IN B. The LT1013ACN8#PBF retains this footprint while delivering superior offset, drift, and single-supply performance without PCB changes.
What packaging and temperature grade does LT1013ACN8#PBF use?
The LT1013ACN8#PBF is packaged in an 8-lead plastic DIP (PDIP) with lead-free finish (#PBF suffix), rated for 0°C to 70°C operating temperature.
