Product details
Overview
LT6013CDD#TRPBF 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 35µV max offset voltage (A-grade), operating from 2.7V to ±18V supplies in a space-saving 3mm × 3mm DFN-8 package.
For engineers reviewing the LT6013CDD#TRPBF datasheet, LT6013CDD#TRPBF pinout, LT6013CDD#TRPBF application, or LT6013CDD#TRPBF equivalent, this page provides verified circuit role, package mapping, thermal performance (θJA = 160°C/W), gain-stability requirements (AV ≥ 5), and real-world design implications for thermocouple amplification, photodiode signal conditioning, and battery-powered instrumentation.
Technical Context
The LT6013CDD#TRPBF employs a decompensated architecture requiring minimum closed-loop gain of 5 for stability-unlike unity-gain stable op amps-and supports 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– paths.
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). Input common-mode range is limited to V– + 1V to V+ – 1.2V, and the underside metal pad is connected to V– for thermal and grounding integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 145µA per amplifier - enables multi-year operation on coin-cell batteries in portable sensor nodes. |
| Input Voltage Noise | 9.5nV/√Hz at 1kHz - preserves SNR in high-gain, low-level analog front-ends like thermocouple amplifiers. |
| Offset Voltage (max) | 85µV over 0°C to 70°C - ensures ≤0.85mV error in 10V full-scale precision measurement systems. |
| Gain Bandwidth Product | 1.4MHz - supports stable closed-loop bandwidths up to ~280kHz at AV = 5, suitable for fast-sampling sensor interfaces. |
| Output Swing | Within 40mV of V+ and V– at no load - maximizes dynamic range in 3.3V or 5V single-supply systems. |
| Input Bias Current (max) | ±400pA over 0°C to 70°C - allows use with >10MΩ feedback networks without significant DC error. |
| CMRR | 107dB min - rejects >99.999% of common-mode interference in noisy industrial environments. |
Pinout & Package
LT6013CDD#TRPBF is housed in an 8-lead plastic DFN package (3mm × 3mm), with exposed underside metal pad connected to V– for thermal dissipation and grounding. The package has θJA = 160°C/W and TJMAX = 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN | Inverting input terminal; requires matched layout and guard ring for <10µV error in high-impedance applications. |
| 2 | +IN | Non-inverting input terminal; sensitive to thermal gradients-keep traces short and symmetric. |
| 3 | V– | Negative supply rail and thermal/ground reference; underside metal pad must be soldered to PCB ground plane. |
| 4 | DNC | Do Not Connect - internal test node; floating connection avoids parasitic coupling. |
| 5 | DNC | Do Not Connect - internal test node; leave unconnected per datasheet. |
| 6 | V+ | Positive supply rail; decoupling capacitor (0.1µF ceramic) required within 2mm of pin. |
| 7 | OUT | Amplifier output; capable of sourcing/sinking 8mA; stable with ≤500pF load at AV ≥ 5. |
| 8 | NC | No Connection - internally unused; may be left floating or tied to V– for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings to within 40mV of both supply rails at no load-enables full utilization of low-voltage ADC input ranges. |
| Low 1/f noise | 200nVP-P (0.1Hz–10Hz)-critical for DC-coupled sensor measurements where drift dominates error budget. |
| Gain-stable at AV ≥ 5 | Eliminates need for external compensation in medium-gain configurations, reducing BOM count and board area. |
| High PSRR | 112dB min-rejects ripple and switching noise from shared power rails in mixed-signal embedded systems. |
| Wide supply range | 2.7V to ±18V operation-supports both ultra-low-power battery systems and legacy industrial ±15V designs. |

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, 200pA input bias current, 14nV/√Hz noise, SO-8 package. | Supports G = 1 configurations (e.g., voltage followers); higher noise limits use in ultra-low-level sensor apps. | Select when unity-gain operation is mandatory and 9.5nV/√Hz noise is not required. |
| LT1881CS8#PBF | Dual-channel, 1pA input bias current, 9.5nV/√Hz noise, unity-gain stable, SO-8. | Enables dual-sensor channels in same footprint; lower IB suits >1GΩ source impedances but higher quiescent current (1.1mA). | Select when dual amplifiers and picoamp input bias are needed, and higher supply current is acceptable. |
Compared with LT6010CS8#PBF and LT1881CS8#PBF, the LT6013CDD#TRPBF offers the lowest noise and lowest supply current in a miniature DFN package-but requires AV ≥ 5 and cannot operate at unity gain, making it optimal for fixed-gain, battery-constrained, high-SNR applications.

FAQ
What is the minimum stable gain for LT6013CDD#TRPBF?
The LT6013CDD#TRPBF is decompensated and requires a minimum closed-loop gain of 5 (AV ≥ 5) for stability. Operating at unity gain or gains below 5 risks oscillation. For G = 1 applications, consider the unity-gain stable LT6010CS8#PBF or LT1881CS8#PBF instead. Stability is confirmed across temperature and supply voltage ranges per the official datasheet.
Does LT6013CDD#TRPBF support rail-to-rail input?
No, the LT6013CDD#TRPBF does not support rail-to-rail input. Its input common-mode voltage range is specified from V– + 1V to V+ – 1.2V. Exceeding this range causes gain collapse but no phase reversal. This limitation must be accounted for in single-supply designs-e.g., with V+ = 5V and V– = 0V, valid input range is 1V to 3.8V.
What is the thermal resistance (θJA) of LT6013CDD#TRPBF?
The LT6013CDD#TRPBF has a junction-to-ambient thermal resistance (θJA) of 160°C/W in the 3mm × 3mm DFN-8 package, with TJMAX = 125°C. Effective thermal performance requires soldering the exposed underside metal pad to a PCB copper pour connected to V–, as specified in the package drawing and layout guidelines.
Can LT6013CDD#TRPBF drive capacitive loads?
Yes-the LT6013CDD#TRPBF can drive up to 500pF capacitive loads while maintaining stability at AV ≥ 5. Driving larger capacitances requires either increasing closed-loop gain or adding a small series resistor (e.g., 10–50Ω) between the output and load to isolate the capacitance from the op amp's output stage.
Is LT6013CDD#TRPBF pin-compatible with other LT6013 variants?
Yes-LT6013CDD#TRPBF shares identical pinout and footprint with all LT6013 DFN-8 variants (e.g., LT6013ACDD#TRPBF, LT6013IDD#TRPBF). Differences lie only in grade (C = commercial, I = industrial), offset voltage, drift, and input bias current specifications-not physical or electrical connectivity.
