Product details
Overview
LT6003IDC#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, 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 –40°C to +85°C, features 500µV max input offset voltage, 90pA max input bias current, and drives 500pF capacitive loads - enabling use in portable gas monitors and low-voltage sensor signal conditioning.
For engineers reviewing the LT6003IDC#TRMPBF datasheet, LT6003IDC#TRMPBF pinout, LT6003IDC#TRMPBF application, or LT6003IDC#TRMPBF equivalent, key selection criteria include guaranteed industrial-temperature performance (–40°C to +85°C), 2mm × 2mm DFN package with exposed V– pad, rail-to-rail CMVR (0V to V+), and ultralow supply current stability across 1.6V–5V operation.
Technical Context
The LT6003IDC#TRMPBF employs a dual-input-stage architecture: a PNP pair active from V– to ~0.9V below V+, and an NPN pair active near V+, enabling true rail-to-rail common-mode input range. Its folded-cascode second stage and complementary drive output stage deliver rail-to-rail output swing while maintaining stability with ≥500pF capacitive loads.
Input offset voltage is trimmed on both input stages to limit total CMRR-induced shift to ≤1.3mV over full VCM range; PSRR (≥78dB) and CMRR (≥60dB) are specified down to 1.6V supply, supporting robust operation in noisy, low-voltage embedded systems without external regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - enables direct operation from single-cell Li-ion (2.7–4.2V), alkaline (1.5V × 2), or energy-harvesting sources without LDO. |
| Quiescent Current | ≤1.6µA at –40°C to +85°C - ensures >10-year battery life in coin-cell–powered IoT sensors drawing <1µA average. |
| Input Offset Voltage | ≤950µV max over –40°C to +85°C - supports 12-bit accuracy in 3.3V systems without trimming. |
| Input Bias Current | ≤90pA max - allows use with >100MΩ sensor bridges (e.g., electrochemical gas cells) without significant error. |
| Capacitive Load Drive | 500pF - eliminates need for isolation resistors when driving ADC input filters or long PCB traces. |
| CMRR / PSRR | ≥60dB / ≥78dB at 1.6V - maintains DC accuracy in unregulated battery rails with high ripple or shared ground noise. |
| Output Swing | Within 100mV of V+ and 50mV of V– (no load) - maximizes dynamic range in single-supply 1.8V/3.3V data acquisition. |
Pinout & Package
LT6003IDC#TRMPBF is housed in a 4-lead (2mm × 2mm) plastic DFN package with exposed pad connected to V–. The package is 0.75mm height, RoHS-compliant, and requires soldering the exposed pad to PCB for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage with ≤100mV headroom to V+ and ≤50mV to V– under no load. |
| 2 (V–) | Negative supply / reference | Exposed pad (Pin 5) is internally tied to V–; must be soldered to PCB ground plane for thermal dissipation and noise immunity. |
| 3 (+IN) | Non-inverting input | Accepts signals from V– to V+; input bias current ≤90pA enables high-Z sensor interfacing. |
| 4 (–IN) | Inverting input | Differential pair node; matched to +IN for <1.3mV CMRR-induced offset shift across full input range. |
| 5 (Exposed Pad) | Thermal & electrical connection to V– | Not a signal pin; mandatory PCB connection for junction temperature control (TJMAX = 125°C) and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization in 1.6V–3.3V systems without level-shifting circuitry or supply boosting. |
| Ultralow 1µA supply current | Reduces average system power by >90% vs. standard precision op amps, extending shelf life of sealed environmental sensors. |
| 500pF capacitive load drive | Permits direct connection to SAR ADC inputs and RC anti-aliasing filters without destabilizing compensation networks. |
| Phase reversal protection | Prevents output polarity inversion when inputs exceed V– by up to 9V - critical for fault-tolerant gas monitor front-ends. |
| Guaranteed –40°C to +85°C operation | Validates performance across automotive cabin, industrial field, and outdoor deployment environments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40007AUT+T | Higher IQ (1.8µA typ), 1.7V min supply, 1.2mV VOS max (–40°C to +85°C) | Less suitable for 1.6V systems; better for 1.8V+ designs requiring higher drive strength (10mA) | Select when higher output current is needed and supply ≥1.7V; avoid for sub-1.7V battery cutoff. |
| OPA310AIDBVR | Lower IQ (150nA), but only specified down to 1.8V supply and 0°C to 70°C temp range | Not qualified for industrial temperature; unsuitable for cold-weather deployments or unregulated 1.6V rails | Choose only for room-temperature, ultra-low-power applications where 1.6V operation and –40°C startup are not required. |

FAQ
What is the minimum supply voltage specification for LT6003IDC#TRMPBF?
The LT6003IDC#TRMPBF is fully specified and guaranteed to operate down to 1.6V supply voltage across its industrial temperature range (–40°C to +85°C), with PSRR and CMRR maintained per datasheet limits. This enables direct interface with aging primary batteries and energy-harvesting sources that dip below 1.8V.
Does LT6003IDC#TRMPBF support rail-to-rail input common-mode voltage?
Yes, the LT6003IDC#TRMPBF supports rail-to-rail input common-mode voltage - from V– to V+ - achieved via dual PNP/NPN input stages. Input offset voltage shift across this range is limited to ≤1.3mV max, ensuring precision remains intact even when signals approach either rail.
What is the function of the exposed pad on the LT6003IDC#TRMPBF DFN package?
The exposed pad (Pin 5) on the LT6003IDC#TRMPBF is electrically and thermally connected to V–. It must be soldered to a PCB copper pour tied to the system V–/ground net to ensure proper thermal dissipation (θJA = 102°C/W) and reduce noise coupling - leaving it floating violates thermal and electrical specifications.
Can LT6003IDC#TRMPBF drive a 100nF capacitor directly?
No - while the LT6003IDC#TRMPBF is rated for 500pF capacitive load stability, driving 100nF (100,000pF) directly will cause severe overshoot and potential oscillation. For such loads, add a series isolation resistor (e.g., 20Ω–100Ω) between the output and capacitor, or use a unity-gain buffer configuration with external compensation.
Is LT6003IDC#TRMPBF pin-compatible with other LT6003 variants like LT6003IS5#TRPBF?
No - LT6003IDC#TRMPBF (4-lead 2mm × 2mm DFN) is not pin-compatible with LT6003IS5#TRPBF (5-lead TSOT-23). The DFN has dedicated V– on Pin 2 and exposed pad (Pin 5); the TSOT-23 places V– on Pin 2 and uses Pin 5 for V+, resulting in incompatible pin mapping and PCB layout.
