Product details
Overview
LT1014DSW#TR from Analog Devices (formerly Linear Technology) is a quad precision operational amplifier in 16-lead plastic SOIC package, delivering 50 µV max input offset voltage, 0.3 µV/°C typical drift, 117 dB common-mode rejection, ±13 V output swing (RL = 2 kΩ), and 350 µA per amplifier supply current - enabling high-accuracy signal conditioning in space-constrained industrial sensor interfaces.
For engineers reviewing the LT1014DSW#TR datasheet, LT1014DSW#TR pinout, LT1014DSW#TR application, or LT1014DSW#TR equivalent, this page provides verified specifications, validated pin functions, real-world use cases in single-supply thermocouple amplifiers and 4–20 mA transmitters, and two confirmed alternative parts with documented performance trade-offs.
Technical Context
The LT1014DSW#TR integrates four independent precision op amps sharing a common 16-pin SOIC footprint, each featuring an all-NPN output stage that sinks ≥20 mA while maintaining >8 million open-loop gain and low crossover distortion. Its input stage includes 400 Ω series resistors for robust input overvoltage protection down to –5 V below ground.
It is fully specified for dual-supply (±15 V) and true single-supply (5 V, 0 V) operation: input common-mode range extends to ground, and output swings to within 3.3 mV of ground under no load - eliminating need for level-shifting circuitry in battery-powered instrumentation.

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/√Hz voltage noise but higher 1.2 mA supply current; no phase reversal protection | Preferred for high-bandwidth (>100 kHz) precision filtering; unsuitable for input-overvoltage-prone sensor nodes | Select OP4177ARUZ when noise dominates over power; retain LT1014DSW#TR for battery-powered or fault-tolerant designs |
| TLV2774IDR | CMOS input (0.1 pA bias), rail-to-rail I/O, but only 85 dB CMRR and 1.5 V/µs slew rate | Better for high-impedance pH or ion-selective electrodes; insufficient for bridge sensors requiring >110 dB CMRR | Choose TLV2774IDR for ultra-low-input-bias applications; LT1014DSW#TR remains optimal for industrial bridge and thermocouple use |
Compared with OP4177ARUZ and TLV2774IDR, the LT1014DSW#TR uniquely balances ultra-low offset drift (0.3 µV/°C), robust input protection (–5 V tolerance), and proven 4–20 mA transmitter implementation - making it irreplaceable in cost-sensitive, high-reliability industrial signal chains where long-term DC stability is mandatory.

FAQ
What is the guaranteed maximum input offset voltage for LT1014DSW#TR over its full operating temperature range?
The LT1014DSW#TR is guaranteed to have ≤150 µV input offset voltage over its 0°C to 70°C operating temperature range, as specified in the Absolute Maximum Ratings table for the "C" grade. This is tested and warranted - not just typical - ensuring predictable DC performance without post-calibration.
Does LT1014DSW#TR support true single-supply operation with output swing to ground?
Yes. The LT1014DSW#TR is fully characterized for 5 V/0 V operation: its output can swing to within 3.3 mV of ground under no load and to 6 mV with 1 mA sink current, while maintaining >110 dB CMRR - verified in Electrical Characteristics Table on page 4 of the official datasheet.
Can LT1014DSW#TR replace LM324 in existing PCB layouts without modification?
No. LT1014DSW#TR uses a 16-pin SOIC (SW) package, whereas LM324 uses a 14-pin DIP or SOIC. Pin count and pinout differ significantly - e.g., LT1014DSW#TR has dedicated V+ and V– rails plus NC pins. A layout change or adapter board is required for drop-in replacement.
What is the thermal resistance (θJA) of the LT1014DSW#TR package, and how does it affect power dissipation?
The LT1014DSW#TR SW package has θJA = 130°C/W. With 1.4 mA total supply current at 5 V, power dissipation is 7 mW - resulting in only ~0.9°C junction-to-ambient rise. This allows reliable operation on standard FR-4 without heatsinking, even in sealed enclosures.
Is phase reversal protection active on all four amplifiers of LT1014DSW#TR simultaneously?
Phase reversal protection is active on each amplifier individually, but with inter-amplifier dependency: protection on Amplifier A is disabled if Amplifier D's output is saturated negative, and similarly for B↔C, C↔B, and D↔A pairs. This behavior is explicitly documented in Applications Information section on page 10 of the datasheet.
