Product details
Overview
LT6003CDC#TRMPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input/output precision operational amplifier optimized for micropower battery-powered systems. It operates from 1.6V to 16V supply, draws ≤1.6µA quiescent current at 5V, features 500µV max input offset voltage (0°C–70°C), 90pA max input bias current, and drives 500pF capacitive loads - enabling high-accuracy signal conditioning in portable gas monitors and low-voltage sensor interfaces.
For engineers reviewing the LT6003CDC#TRMPBF datasheet, LT6003CDC#TRMPBF pinout, LT6003CDC#TRMPBF application, or LT6003CDC#TRMPBF equivalent, this page delivers verified package mapping (4-lead 2mm × 2mm DFN), temperature-grade validation (0°C to 70°C specified), rail-to-rail CMVR/OUT behavior, and real-world start-up current control data critical for ultra-low-power design validation.
Technical Context
The LT6003CDC#TRMPBF employs a dual-input-stage architecture: a PNP pair active from V– to ~0.9V below V+, and an NPN pair engaging near V+ to maintain rail-to-rail common-mode input range. Input offset voltage is trimmed on both stages, limiting total CMRR-induced shift to ≤1.3mV over full VCM.
Its folded-cascode second stage and complementary drive output stage enable stable rail-to-rail swing (≤100mV from rails, no load) while sustaining 100,000 min open-loop gain into 20kΩ and supporting 500pF capacitive load without oscillation - confirmed across –40°C to 125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - enables direct operation from single-cell Li-ion (3.0V), alkaline (1.5V×2), or 12V industrial rails without regulation. |
| Quiescent Current | ≤1.6µA at 5V (–40°C to 85°C) - ensures >1-year battery life in coin-cell-powered IoT sensors with 10µA average system budget. |
| Input Offset Voltage | ≤500µV (0°C to 70°C) - supports 12-bit accuracy in 2.5V full-scale systems without trimming. |
| Input Bias Current | ≤90pA (–40°C to 85°C) - allows use with >100MΩ source impedances (e.g., pH electrodes, photodiode TIA feedback) without significant error. |
| CMRR / PSRR | 100dB CMRR, 95dB PSRR - rejects supply ripple and common-mode noise in noisy industrial or automotive environments. |
| Capacitive Load Drive | 500pF - eliminates need for isolation resistors when driving ADC input filters or long PCB traces. |
| Operating Temperature | Specified 0°C to 70°C, functional –40°C to 125°C - suitable for commercial and extended-temperature embedded applications. |
Pinout & Package
LT6003CDC#TRMPBF is housed in a 4-lead, 2mm × 2mm plastic DFN package (DC grade) with exposed pad connected to V–. The package is RoHS-compliant, halogen-free, and rated for 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Rail-to-rail sourcing/sinking output capable of swinging within 100mV of V+ and 50mV of V– under no load. |
| 2 (V–) | Negative Supply / Ground Reference | Exposed thermal pad (Pin 5) must be soldered to PCB ground plane for thermal management and optimal PSRR. |
| 3 (+IN) | Non-Inverting Input | High-impedance node (2000GΩ common-mode RIN); bias current ≤90pA enables high-Z sensor interfacing. |
| 4 (–IN) | Inverting Input | Differential input with 10GΩ differential RIN; offset voltage trimmed jointly with +IN for <500µV total error. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow Quiescent Current | 1.6µA max at 5V over temperature - reduces self-heating and extends battery runtime in always-on sensing nodes. |
| Rail-to-Rail Input & Output | Full V– to V+ input common-mode range and output swing within 100mV of rails - maximizes dynamic range in single-supply 1.8V/3.3V systems. |
| Phase Reversal Protection | Input stage prevents output polarity inversion when inputs are driven up to 9V below V– - enhances robustness in fault-prone sensor front-ends. |
| Stable Capacitive Load Drive | Guaranteed stability with 500pF load - eliminates external compensation in anti-aliasing filter designs. |
| Low Input Offset Drift | 2µV/°C typical - maintains calibration integrity across temperature gradients in portable medical or environmental instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX44260ASA+ | 2.7V min supply, 1.2µA IQ, 200µV VOS (max), 50pA IB - lower offset but higher VDD requirement. | Not suitable for 1.6V–1.8V single-cell systems; better for 3V+ energy-harvesting nodes. | Select MAX44260ASA+ only if supply ≥2.7V and offset <200µV is mandatory; LT6003CDC#TRMPBF remains superior below 2.5V. |
| OPA333AIDBVR | 1.8V min supply, 17µA IQ, 10µV VOS (max), 200pA IB - 10× higher IQ, 50× lower offset. | Unacceptable for µA-budget systems; appropriate only where ultra-low offset outweighs power penalty. | Choose OPA333AIDBVR for precision instrumentation requiring sub-20µV offset; avoid when supply current must stay <2µA. |
Compared with MAX44260ASA+ and OPA333AIDBVR, LT6003CDC#TRMPBF uniquely balances sub-2µA supply current, 1.6V operation, and 500µV offset - making it the only viable option for long-life, single-cell-powered sensor signal chains where both voltage headroom and power are constrained.

FAQ
What is the maximum capacitive load the LT6003CDC#TRMPBF can drive without instability?
The LT6003CDC#TRMPBF is specified to drive up to 500pF capacitive loads while maintaining stability - confirmed across all supply voltages (1.6V–16V) and temperature ranges (–40°C to 125°C). This eliminates the need for series isolation resistors in ADC input buffering or anti-aliasing filter applications, preserving signal integrity and simplifying layout.
Does the LT6003CDC#TRMPBF support true rail-to-rail input common-mode voltage range?
Yes - the LT6003CDC#TRMPBF accepts input signals from V– to V+ (0V to 1.8V, 0V to 5V, or –8V to +8V depending on supply), enabled by its dual-input-stage architecture (PNP + NPN pairs). Input offset voltage is trimmed on both stages, limiting total common-mode-induced shift to ≤1.3mV over full VCM, ensuring precision across the entire range.
What is the guaranteed operating temperature range for the LT6003CDC#TRMPBF?
The LT6003CDC#TRMPBF is specified over 0°C to 70°C (commercial grade) and guaranteed functional from –40°C to 125°C. Electrical parameters including 500µV max input offset voltage, 90pA max input bias current, and 1.6µA max supply current apply across the 0°C to 70°C range per the datasheet's "LT6003C" designation in the ORDER INFORMATION table.
How does the LT6003CDC#TRMPBF manage start-up current in battery-powered systems?
Unlike many micropower op amps, the LT6003CDC#TRMPBF maintains controlled start-up current (<1.6µA) even during output saturation - preventing supply rail collapse in current-limited battery systems. This behavior is validated in Figure TA01b of the datasheet, showing stable 0.95µA supply current during oxygen sensor circuit start-up.
Is the exposed pad on the LT6003CDC#TRMPBF's DFN package electrically connected?
Yes - the exposed pad (Pin 5) on the LT6003CDC#TRMPBF's 4-lead 2mm × 2mm DFN package is internally connected to V– and must be soldered to the PCB ground plane. This connection is required for thermal dissipation (θJA = 102°C/W), optimal PSRR, and meeting the 125°C junction temperature rating.
