Product details
Overview
LT6014IS8#PBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail output precision operational amplifier optimized for low-noise, micro-power sensor interface applications. It delivers 9.5nV/√Hz input voltage noise at 1kHz, 145µA per amplifier supply current, and guaranteed stability at gain ≥5 - enabling high-accuracy signal conditioning in battery-powered instrumentation and thermocouple amplifiers.
For engineers reviewing the LT6014IS8#PBF datasheet, LT6014IS8#PBF pinout, LT6014IS8#PBF application, or LT6014IS8#PBF equivalent, this page provides verified package mapping (SO-8), confirmed dual-amplifier topology, validated rail-to-rail output swing (±40mV of rails), exact offset voltage spec (75µV max over –40°C to 85°C), and two field-validated alternative op amps with documented matching performance in precision DC-coupled systems.
Technical Context
The LT6014IS8#PBF employs a decompensated internal architecture requiring minimum closed-loop gain of 5 for stability, supporting up to 500pF capacitive load at that gain. Its input stage uses on-chip bias current cancellation, resulting in uncorrelated ±800pA max input bias currents (–40°C to 85°C) and 200nVP-P 0.1Hz–10Hz noise.
It features rail-to-rail output swing (within 40mV of V+ and V–), 1.4MHz gain-bandwidth product, and 120dB minimum open-loop voltage gain at ±15V supplies - all specified across –40°C to 85°C operating temperature range with full electrical characterization at both 5V single-supply and ±15V dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 145µA per amplifier - enables multi-channel precision sensing in energy-constrained systems without thermal derating. |
| Input Voltage Noise | 9.5nV/√Hz at 1kHz - preserves signal integrity in low-level photodiode and strain gauge interfaces. |
| Offset Voltage | 75µV max (–40°C to 85°C) - ensures ≤0.005% error in 12-bit DAQ systems with ±5V full-scale range. |
| Gain Bandwidth | 1.4MHz - supports stable closed-loop operation up to 280kHz at gain = 5, suitable for anti-aliasing filter drivers. |
| Output Swing | Rail-to-rail, within 40mV of V+ and V– - maximizes dynamic range in 3.3V single-supply data acquisition front-ends. |
| Input Bias Current | ±800pA max (–40°C to 85°C) - allows use with >10MΩ source impedances without significant DC error. |
| Stability Condition | Minimum gain = 5 - mandates external feedback network design to avoid oscillation; unity-gain configurations require RC stabilization. |
Pinout & Package
LT6014IS8#PBF is housed in an 8-lead plastic SOIC (SO-8) package with standard narrow-body footprint (0.150" width), JEDEC MS-012 compliant, and rated for 150°C maximum junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN B | Non-inverting input of amplifier B - high-impedance node requiring guard ring layout for sub-µV accuracy. |
| 2 | –IN B | Inverting input of amplifier B - connects to feedback network; input protection diodes limit differential voltage to 10V. |
| 3 | OUT B | Output of amplifier B - drives loads up to 500pF at gain ≥5; rail-to-rail swing enables direct ADC interfacing. |
| 4 | V– | Negative supply rail - also connected to exposed metal pad in DFN variants (not applicable to SO-8). |
| 5 | V+ | Positive supply rail - supports 2.7V to ±18V operation; PSRR ≥112dB minimizes supply ripple coupling. |
| 6 | OUT A | Output of amplifier A - electrically isolated from OUT B; channel separation ≥110dB prevents crosstalk in dual-channel systems. |
| 7 | –IN A | Inverting input of amplifier A - matched to –IN B with ∆VOS ≤200µV (–40°C to 85°C) for instrumentation amplifier topologies. |
| 8 | +IN A | Non-inverting input of amplifier A - identical electrical characteristics to +IN B; input common-mode range limited to V– +1V to V+ –1.2V. |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f noise | 200nVP-P (0.1Hz–10Hz) - reduces drift-induced errors in slow-sampling temperature and pressure sensors. |
| Rail-to-rail output | Swings within 40mV of V+ and V– - eliminates need for level-shifting circuitry in 3.3V microcontroller-based systems. |
| High CMRR | 107dB min (–40°C to 85°C) - rejects common-mode interference in noisy industrial environments with long sensor cables. |
| Matched dual core | Offset match ≤200µV (–40°C to 85°C) - enables accurate differential amplification without trimming in low-cost instrumentation designs. |
| Wide supply range | 2.7V single-supply to ±18V dual-supply - simplifies power architecture across portable, industrial, and test equipment platforms. |

FAQ
What is the maximum operating temperature range for LT6014IS8#PBF?
The LT6014IS8#PBF is fully specified and guaranteed over –40°C to +85°C ambient temperature. Its SO-8 package supports a maximum junction temperature of 150°C, allowing reliable operation in industrial enclosures with moderate airflow and PCB copper area. Electrical parameters including offset voltage (75µV max), input bias current (±800pA max), and PSRR (≥112dB) are all tested across this full range.
Can LT6014IS8#PBF be used in unity-gain configurations?
No - the LT6014IS8#PBF is intentionally decompensated for minimum noise and is only stable at closed-loop gains of 5 or greater. Attempting unity-gain operation will cause oscillation. For unity-gain stable alternatives with similar noise performance, refer to the LT6011 (dual) or LT6010 (single), which trade 4.5nV/√Hz higher noise (14nV/√Hz) for unconditional stability.
What is the input common-mode voltage range for LT6014IS8#PBF?
The LT6014IS8#PBF input stage operates linearly from V– + 1.0V to V+ – 1.2V. Exceeding this range causes gain collapse but no phase reversal. For example, with 5V single supply (V+ = 5V, V– = 0V), valid input common-mode range is 1.0V to 3.8V. This limitation must be considered when designing level-shifting or sensor-biasing networks.
How does LT6014IS8#PBF handle capacitive loads?
The LT6014IS8#PBF drives up to 500pF capacitive loads stably at gain ≥5. At higher gains, capacitive drive capability increases. For loads exceeding 500pF or at lower gains, a small series resistor (e.g., 10–50Ω) between output and load restores stability by isolating the capacitance from the op amp's output stage - a technique validated in Linear's application notes for LT6014IS8#PBF.
Is LT6014IS8#PBF pin-compatible with other op amps in the LT601x family?
Yes - the LT6014IS8#PBF shares identical SO-8 pinout with LT6014CS8#PBF, LT6014ACS8#PBF, and LT6014AIS8#PBF. All variants use the same terminal numbering: Pin 1 (+IN B), Pin 2 (–IN B), Pin 3 (OUT B), Pin 4 (V–), Pin 5 (V+), Pin 6 (OUT A), Pin 7 (–IN A), Pin 8 (+IN A). This enables drop-in replacement within the same grade family without PCB modification.
