Product details
Overview
LT6013CS8#TRPBF from Analog Devices (formerly Linear Technology) is a single, 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, 35µV max input offset voltage (A-grade), 145µA supply current per amplifier, and stable operation at gain ≥5 - enabling high-accuracy thermocouple and photodiode amplification in battery-powered systems.
For engineers reviewing the LT6013CS8#TRPBF datasheet, LT6013CS8#TRPBF pinout, LT6013CS8#TRPBF application, or LT6013CS8#TRPBF equivalent, key selection criteria include guaranteed AV ≥5 stability, 250pA max input bias current (A-grade), 0.2V/µs slew rate, ±18V or 2.7V–36V dual/single-supply operation, and SO-8 package compatibility with industrial temperature range (–40°C to 85°C).
Technical Context
The LT6013CS8#TRPBF employs a decompensated internal architecture requiring minimum closed-loop gain of 5 for stability - unlike unity-gain stable op amps - enabling lower noise and higher bandwidth within its 1.4MHz GBW. Its input stage uses on-chip bias current cancellation, resulting in uncorrelated IB+ and IB–, making traditional input resistor balancing counterproductive.
It features rail-to-rail output swing (within 40mV of rails at no load), 120dB min open-loop voltage gain, and enhanced CMRR/PSRR vs frequency versus legacy precision op amps. Input common-mode range is limited to V– + 1V to V+ – 1.2V, and it supports up to 500pF capacitive load at AV = 5 without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to ±18V - supports single-supply 3V/5V systems and dual-supply ±15V instrumentation |
| Input Offset Voltage (Max) | 35µV (LT6013A grade) - enables sub-100µV system-level DC error in precision sensor front-ends |
| Input Bias Current (Max) | ±250pA (A-grade, TA ≤ 70°C) - preserves accuracy with MΩ-range feedback and source impedances |
| Input Voltage Noise | 9.5nV/√Hz @ 1kHz - dominates total noise only below ~10kΩ source impedance |
| Gain Bandwidth Product | 1.4MHz @ AV ≥5 - sets usable small-signal bandwidth for gain-of-5 configurations |
| Slew Rate | 0.2V/µs - limits full-power bandwidth to ~318kHz for 1V output swing |
| Operating Temperature | –40°C to 85°C - qualified for industrial environments without derating |
Pinout & Package
LT6013CS8#TRPBF is housed in an 8-lead plastic SO (SO-8, narrow 0.150") package with exposed pad connected to V–. Pin 1 is marked by a dot or notch; pin numbering follows standard SO-8 convention (counterclockwise from pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail connection - must be decoupled locally to minimize PSRR degradation |
| 2 | OUT | Amplifier output - capable of rail-to-rail swing; drives loads up to 500pF at AV ≥5 |
| 3 | –IN | Inverting input - protected by 500Ω series resistors and back-to-back diodes |
| 4 | +IN | Non-inverting input - same protection as –IN; differential input voltage limited to ±10V |
| 5 | V– | Negative supply rail - underside metal pad is internally connected to V– (PCB connection optional) |
| 6 | NC | No connect - not internally bonded; leave floating or ground per layout best practices |
| 7 | DNC | Do not connect - unused terminal; must remain unconnected |
| 8 | DNC | Do not connect - unused terminal; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 40mV of V+ and V– at no load - maximizes dynamic range in low-voltage single-supply systems |
| Low 1/f noise | 200nVP-P (0.1Hz–10Hz) - critical for DC-coupled sensor amplifiers where drift and flicker dominate |
| AV ≥5 stability | Guaranteed stable at closed-loop gain ≥5 - enables lower noise and higher GBW than unity-gain alternatives |
| High PSRR & CMRR | 112dB min PSRR and 107dB min CMRR over full temp range - maintains accuracy in noisy or unbalanced supply environments |
| Micro-power operation | 145µA per amplifier at 5V - extends battery life in portable instrumentation and IoT sensor nodes |

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#TRPBF | Unity-gain stable, 14nV/√Hz noise, 200pA IB, includes shutdown pin | Supports gain-of-1 configurations; trades noise performance for flexibility in low-gain circuits | Select when gain <5 is required or power gating is needed; not drop-in due to different stability and pinout |
| OPA333AIDR | Zero-drift architecture, 0.02µV/°C drift, 17µV max VOS, 35nV/√Hz noise, 50pA IB | Superior DC precision but higher broadband noise; optimized for ultra-low drift, not low-noise AC | Select for <0.1°C thermal drift-critical systems; avoid where 1/f noise or 9.5nV/√Hz matters most |
Compared with LT6010CS8#TRPBF and OPA333AIDR, the LT6013CS8#TRPBF uniquely balances ultra-low voltage noise, micro-power consumption, and rail-to-rail output in a gain-stable configuration - making it optimal for battery-powered, medium-bandwidth precision sensor interfaces where noise floor and supply current are primary constraints.

FAQ
What is the minimum stable gain for LT6013CS8#TRPBF?
The LT6013CS8#TRPBF is decompensated and specified for stable operation only at closed-loop gain ≥5. Using it at unity gain or gain-of-2 risks oscillation and instability. For gain <5 applications, consider the unity-gain stable LT6010CS8#TRPBF instead. Stability is verified per manufacturer test conditions across –40°C to 85°C.
Does LT6013CS8#TRPBF support single-supply operation?
Yes, LT6013CS8#TRPBF operates from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies. Its rail-to-rail output swings within 40mV of either rail at no load, and input common-mode range extends from V– + 1V to V+ – 1.2V - enabling robust single-supply use with proper level-shifting or reference design.
What is the maximum capacitive load LT6013CS8#TRPBF can drive?
LT6013CS8#TRPBF can directly drive up to 500pF capacitive load when configured at gain ≥5. Driving larger capacitances requires external isolation resistance (e.g., 10–100Ω in series with output) or increased closed-loop gain. Stability margin degrades rapidly below gain-of-5, especially with capacitive loading.
Is LT6013CS8#TRPBF pin-compatible with other SO-8 op amps?
No - LT6013CS8#TRPBF has two DNC (do-not-connect) pins (7 and 8) and one NC (no-connect) pin (6), differing from standard SO-8 op amp pinouts like LM358 or OPAx333. Its pin 1–5 assignment (V+, OUT, –IN, +IN, V–) matches conventional SO-8, but unused pins must remain unconnected per datasheet. PCB layout must accommodate this unique pin mapping.
What grade does LT6013CS8#TRPBF correspond to?
LT6013CS8#TRPBF is the commercial-grade (C-temp) version: guaranteed functional from 0°C to 70°C and characterized for –40°C to 85°C operation. It offers 60µV max input offset voltage (TA = 0°C to 70°C) and 85µV max over –40°C to 85°C, distinguishing it from the tighter-tolerance LT6013AS8#TRPBF (35µV max, A-grade).
