Product details
Overview
LT1014ISW#TRPBF from Analog Devices (formerly Linear Technology) is a quad precision operational amplifier in 16-lead plastic SOIC package, featuring 50 µV typical input offset voltage, 0.3 µV/°C drift, 0.15 nA offset current, 8 million open-loop gain, and 117 dB common-mode rejection - enabling high-accuracy signal conditioning in space-constrained industrial sensor interfaces.
For engineers reviewing the LT1014ISW#TRPBF datasheet, LT1014ISW#TRPBF pinout, LT1014ISW#TRPBF application, or LT1014ISW#TRPBF equivalent, this page delivers verified specifications, real-world use cases for thermocouple amplification and 4–20 mA transmitters, and validated alternative options with documented parameter trade-offs.
Technical Context
The LT1014ISW#TRPBF employs an all-NPN output stage that enables rail-to-rail sinking capability down to within 3.2 mV of ground under 1 mA load while maintaining >1.5 million voltage gain at ±15 V supply - eliminating crossover distortion in single-supply configurations. Its input stage integrates 400 Ω series protection resistors and phase-reversal suppression circuitry (Q21–Q28), allowing safe operation with inputs up to 5 V below ground without latch-up or output inversion.
It is fully characterized for both dual-supply (±15 V) and single-supply (5 V) operation across –40°C to +85°C, with guaranteed 150 µV max offset voltage, 2 µV/°C max drift, and 0.8 nA max offset current - meeting precision requirements for strain gauge bridges and thermocouple cold-junction compensation where offset stability dominates system accuracy.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower 60 nV offset, 0.2 µV/°C drift, but 1.2 mA supply current per amp - 3.4× higher power draw | Better DC precision, but unsuitable for battery-powered designs requiring <2 mA total supply | Select OP4177ARUZ only when ultra-low offset dominates over power and cost constraints |
| TLV2464IDR | Higher 250 µV max offset, 2.5 µV/°C drift, but rail-to-rail I/O and 550 µA supply current - optimized for low-voltage CMOS systems | Compatible with 2.7–6 V supplies and digital logic interfaces, but lacks guaranteed specs below 0°C | Choose TLV2464IDR for portable consumer devices needing RRO and wide supply range, not industrial-grade DC accuracy |
Compared with OP4177ARUZ and TLV2464IDR, the LT1014ISW#TRPBF uniquely balances sub-150 µV guaranteed offset, 350 µA low supply current, and –40°C to +85°C industrial temperature rating - making it optimal for cost-sensitive, battery-aware precision analog front-ends where long-term calibration stability is mandatory.

FAQ
What is the operating temperature range for LT1014ISW#TRPBF?
The LT1014ISW#TRPBF is rated for operation from –40°C to +85°C (Industrial grade). This range is explicitly guaranteed for all key parameters including input offset voltage (150 µV max), offset drift (2 µV/°C max), and supply current (500 µA max per amplifier), ensuring consistent performance in demanding environmental conditions without derating.
Does LT1014ISW#TRPBF support true single-supply operation with output swing to ground?
Yes, the LT1014ISW#TRPBF supports true single-supply operation from 5 V. Its all-NPN output stage sinks to within 3.2 mV of ground at 1 mA load and sources up to 4.4 V - enabling direct interface with TTL/CMOS logic and elimination of negative rails in portable instrumentation. Input common-mode range also extends to ground.
Is LT1014ISW#TRPBF pin-compatible with LM324 or OP-11?
No, LT1014ISW#TRPBF is not pin-compatible with LM324 or OP-11. It uses a 16-pin SOIC (SW) package with unique pinout: Pins 1–7 and 9–15 assigned to four amplifiers and supplies, while Pins 8 and 16 are NC. LM324 uses 14-pin DIP/SO, and OP-11 uses 8-pin metal can - requiring PCB redesign for replacement.
What is the guaranteed input offset voltage specification for LT1014ISW#TRPBF?
The guaranteed input offset voltage for LT1014ISW#TRPBF is 150 µV maximum at TA = 25°C and VS = ±15 V, and 250 µV maximum under single 5 V supply conditions. This specification is tested and warranted across the full –40°C to +85°C operating range, distinguishing it from typical-only values found in many general-purpose op amps.
Can LT1014ISW#TRPBF be used in comparator applications?
Yes, LT1014ISW#TRPBF is suitable for precision comparator applications due to its low input offset (50 µV typ), high open-loop gain (8 million), and TTL-compatible output swing on single 5 V supply. Application Note 10134fe shows direct use as comparators alongside op-amp functions on the same die - e.g., two amplifiers for signal conditioning and two as window comparators in sensor threshold detection.
