Product details
Overview
LT1014ISW#PBF from Analog Devices (formerly Linear Technology) is a precision quad operational amplifier in a 16-lead plastic SOIC package, featuring 50 µV max input offset voltage, 0.3 µV/°C drift, 0.15 nA offset current, 8 million open-loop gain, and 117 dB common-mode rejection. It operates from ±15 V or single 5 V supply with rail-to-rail input (including ground) and output swing to within millivolts of ground - used in thermocouple amplifiers, strain gauge signal conditioners, and 4–20 mA current loop transmitters.
For engineers reviewing the LT1014ISW#PBF datasheet, LT1014ISW#PBF pinout, LT1014ISW#PBF application, or LT1014ISW#PBF equivalent, key selection criteria include guaranteed 150 µV max offset voltage, low 0.3 µV/°C drift over –40°C to +85°C, 0.55 µVP-P 0.1–10 Hz noise, 20 mA output drive capability, and compatibility with LM324/LM348 pinouts for drop-in upgrades in space-constrained instrumentation designs.
Technical Context
The LT1014ISW#PBF implements an all-NPN input stage with balanced differential pair architecture and proprietary phase-reversal protection circuitry (Q21–Q28), enabling robust operation when inputs fall up to 5 V below ground without latch-up or output inversion - critical for single-supply sensor front-ends. Its output stage maintains high open-loop gain (>0.8 million at 17 mA load) while sourcing/sinking >20 mA, eliminating crossover distortion seen in legacy single-supply op amps like LM324.
It supports dual ±15 V and single 5 V operation with full specifications across both conditions: input common-mode range extends to V– (ground in single-supply mode), output swings to within 3.3 mV of ground (RL = 600 Ω), and channel separation exceeds 120 dB at 1 kHz - enabling multi-channel precision signal conditioning without crosstalk-induced measurement error.

Applications
| Thermocouple Amplification | Strain Gauge Signal Conditioning |
|---|---|
Use Scenario: Amplifying µV-level K-type thermocouple outputs with cold-junction compensation across 0°C–60°C ambient range. IC Role / Device Role / Timing Role: Precision DC-coupled instrumentation amplifier front-end; one LT1014ISW#PBF channel handles cold-junction compensation, others provide gain and filtering. Use Value: Achieves ±1°C accuracy without external offset trim, leveraging 50 µV offset and 0.3 µV/°C drift to minimize calibration burden. | Use Scenario: Conditioning Wheatstone bridge outputs from metal foil strain gauges in load cells and pressure transducers. IC Role / Device Role / Timing Role: Low-noise, low-drift instrumentation amplifier core; two LT1014ISW#PBF channels form 3-op-amp topology with matched RG gain-setting resistor. Use Value: 0.55 µVP-P noise and 117 dB CMRR reject bridge excitation ripple and EMI, enabling 120 dB dynamic range in 350 Ω bridge designs. |
| 4–20 mA Current Loop Transmitter | Active Filter Bank |
Use Scenario: Converting 0–4 V analog sensor outputs into fully floating 4–20 mA process signals compliant with industrial HART protocols. IC Role / Device Role / Timing Role: Dual op-amp configuration: one as voltage-controlled current source, second as feedback integrator for loop stability. Use Value: >20 mA output drive and rail-to-rail swing allow direct control of 250 Ω shunt with 5 V supply - no external pass transistor required. | Use Scenario: Implementing cascaded 2nd-order low-pass and band-pass filters in data acquisition front-ends for vibration monitoring. IC Role / Device Role / Timing Role: Quad op-amp used as independent filter sections: two for LPF, one for BPF, one for buffer - all sharing single 5 V rail. Use Value: 120 dB channel separation prevents inter-stage coupling; 0.4 V/µs slew rate supports ≤10 kHz filter cutoffs with <0.1 dB passband ripple. |
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 0.3 µV/°C drift but higher 1.2 µV offset; 10 MHz GBW vs 0.4 MHz; SOIC-16 pinout identical | Better for high-speed precision (e.g., fast-settling data acquisition); less optimal for ultra-low-offset DC apps | Select OP4177ARUZ when bandwidth >1 MHz required; retain LT1014ISW#PBF for lowest offset in <100 kHz sensor apps |
| LM324DR | Higher 3 mV offset, 10 µV/°C drift, no phase-reversal protection; same SOIC-14 footprint (requires adapter) | Suitable only for non-critical cost-sensitive apps; cannot replace LT1014ISW#PBF in precision thermocouple or RTD circuits | Use LM324DR only for prototyping or non-precision signal buffering; LT1014ISW#PBF remains mandatory for metrology-grade designs |
Compared with OP4177ARUZ and LM324DR, the LT1014ISW#PBF uniquely delivers the lowest guaranteed offset (150 µV max) with integrated phase-reversal protection and ground-swing output - making it irreplaceable in single-supply, high-accuracy sensor interfaces where offset stability and fault tolerance are non-negotiable.

FAQ
What is the operating temperature range for LT1014ISW#PBF?
The LT1014ISW#PBF is rated for operation from –40°C to +85°C (I-grade). This range is validated per manufacturer specifications and supports industrial environments including factory automation and outdoor sensor nodes. All key parameters - including 150 µV max offset voltage and 0.3 µV/°C drift - are guaranteed across this full range, unlike commercial-grade variants limited to 0°C–70°C.
Does LT1014ISW#PBF support true single-supply operation with rail-to-rail input and output?
Yes, the LT1014ISW#PBF supports true single-supply operation from 5 V. Its input common-mode range extends to V– (ground), and its output swings to within 3.3 mV of ground with 600 Ω load - verified per datasheet Figure 10 (TPC13). Unlike LM324, it does not require pull-down resistors or level-shifting networks, enabling direct interfacing with 5 V microcontrollers and SAR ADCs.
Can LT1014ISW#PBF replace LM324 in existing designs without PCB changes?
No - the LT1014ISW#PBF uses a 16-lead SOIC (SW) package, while LM324 uses 14-lead PDIP or SOIC. However, it is pin-compatible with the industry-standard 14-pin DIP LM324/LM348 *functionally and electrically*, meaning the same signal assignments apply to pins 1–7 and 9–14 on the LT1014ISW#PBF (with Pins 8 and 16 as NC). Adapter boards or SW-to-DIP breakouts enable drop-in replacement.
What is the maximum output current capability of LT1014ISW#PBF?
The LT1014ISW#PBF can source and sink more than 20 mA continuously per amplifier, as confirmed in the "Typical Performance Characteristics" section (TPC13, TPC19) and Absolute Maximum Ratings table. This is sufficient to drive standard 250 Ω 4–20 mA loop shunts directly from a 5 V supply without external transistors - a key differentiator versus LM324 (±20 mA short-circuit, but only ±40 mA peak).
Is LT1014ISW#PBF suitable for thermocouple amplifier designs requiring cold-junction compensation?
Yes - the LT1014ISW#PBF is explicitly referenced in Linear Technology's Application Note 10134fe (Figure TA02) for 3-channel thermocouple thermometers with YSI 44007 thermistors and cold-junction compensation accurate to ±1°C from 0°C to 60°C. Its low 0.3 µV/°C drift, 50 µV offset, and single-supply ground-swing output make it ideal for this application without external trimming components.
