Product details
Overview
LT6013IS8#TRPBF from Analog Devices (acquired 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, 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 LT6013IS8#TRPBF datasheet, LT6013IS8#TRPBF pinout, LT6013IS8#TRPBF application, or LT6013IS8#TRPBF equivalent, key selection criteria include its guaranteed –40°C to 85°C industrial temperature range, SO-8 package compatibility, 250pA max input bias current (A-grade), and stability with up to 500pF capacitive load - critical for precision analog front-ends in portable instrumentation and low-voltage industrial sensing.
Technical Context
The LT6013IS8#TRPBF employs a decompensated internal architecture requiring minimum closed-loop gain of 5 for stability, distinguishing it from unity-gain stable op amps. Its input stage uses on-chip bias current cancellation, resulting in uncorrelated IB+ and IB– and making input resistor balancing counterproductive.
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 - essential for DC-coupled microvolt-level signal conditioning where 1/f noise dominates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to ±18V - supports single-supply 3V/5V and dual-supply ±15V operation without level-shifting. |
| Input Offset Voltage (Max) | 35µV (A-grade, TA = –40°C to 85°C) - enables sub-100µV system-level DC accuracy in precision measurement paths. |
| Input Bias Current (Max) | ±250pA (A-grade, TA = 0°C to 70°C) - permits use with >10MΩ source impedances without significant error. |
| Input Voltage Noise | 9.5nV/√Hz @ 1kHz - sets fundamental noise floor for medium-bandwidth precision amplification. |
| Slew Rate | 0.2V/µs - sufficient for settling <10V steps within 20µs at 0.01% accuracy, suitable for slow-scan data acquisition. |
| Gain Bandwidth Product | 1.4MHz - defines maximum usable closed-loop bandwidth at gain=5 (280kHz) or gain=10 (140kHz). |
| CMRR / PSRR | 107dB / 112dB (min, full temp range) - maintains DC accuracy despite supply ripple or common-mode transients. |
Pinout & Package
LT6013IS8#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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No Connect) | Internally unused; must be left floating or grounded - not for signal routing. |
| 2 | –IN | Inverting input terminal; high-impedance node sensitive to layout-induced leakage and thermal gradients. |
| 3 | +IN | Non-inverting input terminal; matched to –IN for CMRR; guard ring recommended in high-Z designs. |
| 4 | V– | Negative supply rail; also connects to exposed thermal pad - requires low-impedance PCB connection for thermal management. |
| 5 | V+ | Positive supply rail; decoupling capacitor (0.1µF) required within 5mm for stability. |
| 6 | OUT | Amplifier output; capable of sourcing/sinking 8mA; rail-to-rail swing limited to ≥40mV from rails under load. |
| 7 | NC (No Connect) | Internally unused; must be left floating or grounded - not for signal routing. |
| 8 | DNC (Do Not Connect) | Factory test pin; electrically isolated - must remain unconnected in final design. |
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 (e.g., 3.3V) single-supply systems. |
| Low 1/f noise | 200nVP-P (0.1Hz–10Hz) - minimizes drift and baseline wander in DC-coupled sensor interfaces like thermocouples. |
| Gain ≥5 stability | Stable with up to 500pF capacitive load at AV=5 - eliminates need for external compensation in buffered DAC outputs or long-line drivers. |
| Industrial temperature grade | Specified from –40°C to +85°C - ensures parametric compliance across automotive cabin, industrial PLC, and outdoor sensor environments. |
| Low input bias current | 250pA max (A-grade) - enables direct interfacing with high-impedance sources (e.g., pH electrodes, piezoresistive sensors) without guard buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6013CS8#TRPBF | Commercial grade (0°C to 70°C); 60µV max VOS (vs. 35µV); same SO-8 package and pinout. | Not rated for –40°C operation; unsuitable for cold-environment industrial deployments. | Select only for cost-sensitive, room-temperature applications where extended temperature range is unnecessary. |
| LT6010IS8#TRPBF | Unity-gain stable; higher 14nV/√Hz noise; includes shutdown pin; 200pA max IB. | Supports gain=1 configurations (e.g., voltage followers) but trades off noise and power efficiency. | Choose when unity-gain buffering is required and 9.5nV/√Hz noise is not critical; avoid if minimizing system noise is primary goal. |
Compared with LT6013CS8#TRPBF, the LT6013IS8#TRPBF provides guaranteed industrial temperature operation and tighter offset specs, while LT6010IS8#TRPBF sacrifices low-noise performance for unity-gain flexibility - making LT6013IS8#TRPBF optimal for fixed-gain, low-noise, wide-temperature precision amplification.

FAQ
What is the operating temperature range specified for the LT6013IS8#TRPBF?
The LT6013IS8#TRPBF is guaranteed over the industrial temperature range of –40°C to +85°C. This specification is explicitly confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet, with all key parameters (e.g., VOS, IB, GBW) tested and warranted across this full range - unlike commercial-grade variants such as LT6013CS8#TRPBF.
Can the LT6013IS8#TRPBF be used in unity-gain configurations?
No, the LT6013IS8#TRPBF is intentionally decompensated and not unity-gain stable. It requires a minimum closed-loop gain of 5 for stability. Attempting unity-gain operation risks oscillation and degraded performance. For unity-gain applications, Analog Devices recommends the LT6010IS8#TRPBF - a functionally similar but unity-gain stable alternative with slightly higher noise (14nV/√Hz).
What is the maximum capacitive load the LT6013IS8#TRPBF can drive reliably?
The LT6013IS8#TRPBF can drive up to 500pF capacitive load while maintaining stability at a gain of 5. This capability increases at higher gains. Driving loads exceeding this limit without proper compensation (e.g., series output resistor) may cause peaking or oscillation - particularly critical in applications like driving ADC input filters or long PCB traces.
How does the input bias current specification of the LT6013IS8#TRPBF impact high-impedance sensor interfacing?
The LT6013IS8#TRPBF specifies a maximum input bias current of ±250pA (A-grade, 0°C to 70°C), enabling accurate interfacing with high-impedance sources such as photodiodes, pH electrodes, or piezoresistive sensors. Because IB+ and IB– are uncorrelated due to on-chip cancellation, matching input resistances does not reduce offset - instead, minimizing absolute resistance at both inputs preserves DC accuracy.
Is the LT6013IS8#TRPBF pin-compatible with other op amps in the LT601x family?
Yes, the LT6013IS8#TRPBF shares identical SO-8 pinout with LT6013CS8#TRPBF, LT6013ACS8#TRPBF, and LT6013AIS8#TRPBF. However, it is not pin-compatible with dual-channel LT6014 variants (e.g., LT6014IS8#TRPBF), which use different pin assignments for dual-amplifier functionality. Always verify pin mapping against the specific device's package drawing before board layout.
