Product details
Overview
LT1014CN#PBF from Analog Devices (formerly Linear Technology) is a quad precision operational amplifier in 14-lead PDIP 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. 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-enabling precision signal conditioning in battery-powered instrumentation.
For engineers reviewing the LT1014CN#PBF datasheet, LT1014CN#PBF pinout, LT1014CN#PBF application, or LT1014CN#PBF equivalent, key selection criteria include guaranteed 150 µV max offset voltage, single-supply operation down to 3.4 V, low 0.55 µVP-P (0.1–10 Hz) noise, 20 mA output drive capability, and compatibility with LM324/LM348 footprint for drop-in upgrades.
Technical Context
The LT1014CN#PBF employs an all-NPN output stage enabling true ground-sinking capability without crossover distortion, even under single 5 V supply. Its phase-reversal protection circuitry prevents output inversion when inputs go up to −1.5 V below ground-critical for transient-tolerant sensor front-ends.
Internally, it integrates four independent high-gain amplifiers sharing no inter-stage coupling beyond substrate-level thermal interaction; channel separation exceeds 120 dB at 1 kHz, supporting multi-channel precision applications like thermocouple amplifiers and active filters where crosstalk must be minimized.
Key Specifications

| Supply Current | 350 µA per amp typ / 500 µA max - supports ultra-low-power 9 V battery operation (≈1 mW/amp at 3.4 V) |
| Output Drive | ±20 mA min - drives 600 Ω loads while maintaining >0.8 million gain, eliminating external buffers in current-loop transmitters |
| Input Noise | 0.55 µVP-P (0.1–10 Hz) - suitable for strain gauge and thermocouple amplification with <0.1 µV resolution |
| CMRR | 117 dB typ - rejects common-mode interference in 4–20 mA loop receivers and bridge sensors |
| PSRR | 120 dB typ - maintains accuracy despite ±2 V to ±18 V supply variation or ripple on shared rails |
| Gain-Bandwidth | 0.4 MHz typ - sufficient for DC–100 Hz sensor bandwidths with >60 dB closed-loop gain margin |

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 max offset but higher 1.2 mA supply current; 10 MHz GBW vs. 0.4 MHz | Better for high-speed precision filtering; unsuitable for battery-powered 9 V systems due to 4.8× higher quiescent power | Select OP4177ARUZ only when bandwidth >100 kHz and supply current >1 mA is acceptable |
| TL074CDR | Higher 10 mV max offset, 18 V/µs slew rate, JFET input (50 pA bias), no guaranteed single-supply swing to ground | Acceptable for AC-coupled audio or non-critical industrial controls; cannot replace LT1014CN#PBF in DC-coupled sensor front-ends | Choose TL074CDR only for cost-sensitive AC applications where offset drift and ground-swing are non-critical |
Compared with OP4177ARUZ and TL074CDR, the LT1014CN#PBF uniquely balances ultra-low offset (150 µV max), ground-sinking capability on single 5 V, and 350 µA quiescent current-making it irreplaceable in portable precision instrumentation where power, accuracy, and rail-to-rail operation intersect.

FAQ
What is the maximum supply voltage rating for LT1014CN#PBF?
The LT1014CN#PBF has an absolute maximum supply voltage rating of ±22 V across V+ and V− terminals. Operation beyond this limit risks permanent damage. For reliable long-term use, Analog Devices specifies ±15 V as the recommended maximum dual-supply voltage, and 5 V as the standard single-supply configuration-both fully characterized in the datasheet with guaranteed performance across 0°C to 70°C.
Does LT1014CN#PBF support true rail-to-rail output swing?
The LT1014CN#PBF does not provide full rail-to-rail output swing but achieves near-rail performance: output can swing to within 4 mV of ground (when sinking current) and to within 6 mV of V+ (when sourcing), as verified under RL = 600 Ω load at 25°C. This ground-sinking capability-unavailable in earlier LM324-family op amps-is enabled by its all-NPN output stage and is explicitly guaranteed in single 5 V operation per the datasheet's Electrical Characteristics table.
Can LT1014CN#PBF be used as a comparator?
Yes, the LT1014CN#PBF can function as a precision comparator with TTL-compatible output levels when operated from a single 5 V supply. Its low offset voltage (150 µV max) and fast 0.2 V/µs slew rate enable accurate threshold detection. However, it lacks dedicated comparator features like internal hysteresis or open-collector output; external positive feedback is required for noise immunity, and output loading must remain within its 20 mA drive specification to avoid saturation delays.
What is the thermal resistance (θJA) of the LT1014CN#PBF package?
The LT1014CN#PBF uses a 14-lead plastic DIP (N-package) with a junction-to-ambient thermal resistance (θJA) of 100°C/W, as specified in the Absolute Maximum Ratings section. This value assumes standard JEDEC 2S2P board conditions (two-layer PCB with 1 in² copper pour per side). Actual thermal performance may improve with added copper area or airflow, but derating is required above 70°C ambient to maintain reliability within the 150°C maximum junction temperature limit.
Is LT1014CN#PBF pin-compatible with LM324?
Yes, the LT1014CN#PBF is pin-compatible with the industry-standard 14-pin DIP LM324, LM348, OP-11, and 4156 packages. Pin assignments for all four amplifiers-including V+, V−, outputs, and inputs-are identical. This allows direct replacement in existing designs without PCB modification, upgrading performance from LM324's 3 mV offset and 20 µA supply current to LT1014CN#PBF's 150 µV offset and 350 µA per amplifier-while retaining full functional compatibility.
