Product details
Overview
LT6013IDD#PBF from Analog Devices (formerly Linear Technology) is a single-channel, 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 supply current per amplifier, and ≤85µV max input offset voltage over –40°C to 85°C - enabling high-accuracy thermocouple and photodiode amplification in battery-powered systems.
For engineers reviewing the LT6013IDD#PBF datasheet, LT6013IDD#PBF pinout, LT6013IDD#PBF application, or LT6013IDD#PBF equivalent, key selection considerations include its AV ≥5 stability requirement, 3mm × 3mm DFN-8 package with exposed V– pad, ±1.35V to ±18V dual-supply operation, and guaranteed performance across industrial temperature range without derating.
Technical Context
The LT6013IDD#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, yielding ±250pA max input bias current (A-grade) and uncorrelated IB+ / IB– behavior critical for high-impedance source accuracy.
It features rail-to-rail output swing (within 40mV of rails at no load), 1.4MHz gain-bandwidth product, and exceptional low-frequency noise performance: 40nVRMS (0.1Hz–10Hz) and 200nVP-P - making it suitable for DC-coupled precision signal conditioning where 1/f noise dominates error budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 145µA per amplifier - enables multi-year battery life in portable instrumentation |
| Input Voltage Noise | 9.5nV/√Hz at 1kHz - preserves SNR in low-level sensor signals (e.g., thermocouples) |
| Input Offset Voltage | ≤85µV (–40°C to 85°C) - ensures <0.1% error in 100mV full-scale measurements |
| Gain Bandwidth Product | 1.4MHz - supports stable closed-loop gains ≥5 up to ~280kHz bandwidth |
| Output Swing | Rail-to-rail (within 40mV of V+ or V– at no load) - maximizes dynamic range in 3.3V or 5V single-supply systems |
| Input Bias Current | ±250pA max (A-grade) - allows use with >10MΩ feedback networks without significant offset drift |
| Operating Temp Range | –40°C to 85°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
LT6013IDD#PBF is housed in an 8-lead 3mm × 3mm plastic DFN package with underside metal pad connected to V–. The exposed thermal pad improves power dissipation and must be soldered to PCB ground plane for optimal thermal performance and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN | Inverting input terminal; high-impedance node requiring guarded layout to minimize leakage |
| 2 | +IN | Non-inverting input terminal; matched to Pin 1 for CMRR optimization |
| 3 | V– | Negative supply rail; also connects to exposed thermal pad for thermal and electrical reference |
| 4 | DNC | Do Not Connect - internal node; floating connection causes instability or ESD risk |
| 5 | DNC | Do Not Connect - internal node; must remain unconnected per datasheet |
| 6 | V+ | Positive supply rail; supports 2.7V to 36V total supply range (±1.35V to ±18V) |
| 7 | OUT | Amplifier output; capable of sourcing/sinking 8mA with rail-to-rail swing into 2kΩ load |
| 8 | NC | No Connection - internally unused; leave unconnected and unstubbed |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f noise | 200nVP-P (0.1Hz–10Hz) - minimizes drift-induced errors in DC-coupled measurement systems |
| Stable at AV ≥5 | Guaranteed phase margin >45° at gain ≥5 - eliminates need for external compensation in standard configurations |
| Rail-to-rail output | Swings within 40mV of either rail at no load - extends usable signal range in low-voltage systems |
| High PSRR | 112dB min (–40°C to 85°C) - rejects supply ripple in noisy embedded power domains |
| Low VOS drift | 0.2µV/°C typical - maintains calibration integrity across wide ambient temperature swings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6010CS8#PBF | Unity-gain stable; higher 14nV/√Hz noise; includes shutdown pin | Supports G = 1 configurations; trades noise for flexibility in gain-setting | Select when unity-gain buffer or power gating is required; not drop-in compatible due to different stability and pinout |
| OPA333AIDBVR | Zero-drift architecture; 0.1µV/°C max drift; 17µA supply current; SOT-23-5 | Better long-term drift spec but lower bandwidth (350kHz); smaller footprint | Select for ultra-low drift in low-bandwidth (<100kHz) applications where size and power dominate; requires redesign for DFN-8 layout |
Compared with LT6013IDD#PBF, LT6010CS8#PBF offers gain flexibility at the cost of noise and power efficiency, while OPA333AIDBVR provides superior drift performance in a smaller package but sacrifices bandwidth and noise density - making LT6013IDD#PBF optimal for industrial sensor interfaces demanding balanced noise, power, and stability.

FAQ
What is the minimum stable gain for LT6013IDD#PBF?
The LT6013IDD#PBF is decompensated and requires a minimum closed-loop gain of 5 for stability. Configurations with gain less than 5 - including unity-gain followers - will oscillate unless external compensation (e.g., RC network across inputs) is applied per Figure 2 in the datasheet. This design choice enables lower noise and higher bandwidth than unity-gain-stable alternatives.
Does LT6013IDD#PBF support single-supply operation?
Yes, LT6013IDD#PBF supports true single-supply operation from 2.7V to 36V total supply range. Its rail-to-rail output swings within 40mV of both rails, and input common-mode range extends from V– + 0.7V to V+ – 1.2V - allowing direct interfacing with 0–3.3V or 0–5V microcontroller ADCs without level-shifting circuitry.
What is the purpose of the exposed metal pad on the LT6013IDD#PBF DFN package?
The exposed metal pad on the bottom of the LT6013IDD#PBF DFN package is electrically connected to the V– pin and serves dual thermal and electrical functions. It must be soldered to a PCB copper pour tied to the system V–/ground net to ensure proper heat dissipation, reduce thermal resistance (θJA = 160°C/W), and minimize noise coupling into the sensitive input stage.
Can LT6013IDD#PBF drive large capacitive loads?
LT6013IDD#PBF can directly drive up to 500pF capacitive loads when configured with gain ≥5. At higher gains, capacitive drive capability increases. For loads exceeding 500pF or for gains <5, a small series resistor (e.g., 10–50Ω) between the output and capacitor restores stability by isolating the reactive load from the amplifier's feedback loop.
How does LT6013IDD#PBF handle input overvoltage conditions?
LT6013IDD#PBF includes internal back-to-back diodes and 500Ω series resistors on both inputs, limiting differential input current to ≤10mA for ≤10V differential input. For applications expecting >10V differential transients (e.g., ESD or sensor disconnect), external 1kΩ series resistors per input are recommended to maintain safe current limits and prevent latch-up or parametric shift.
