Product details
Overview
LT6003HDC#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 5V, features 500µV max input offset voltage (–40°C to 125°C), 90pA max input bias current, and drives 500pF capacitive loads - enabling use in portable gas monitors and low-voltage sensor front-ends.
For engineers reviewing the LT6003HDC#TRMPBF datasheet, LT6003HDC#TRMPBF pinout, LT6003HDC#TRMPBF application, or LT6003HDC#TRMPBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, 2µV/°C offset drift, rail-to-rail swing within 100mV of rails, and compatibility with ultra-low-power signal conditioning where supply current <2µA and input bias <100pA are mandatory.
Technical Context
The LT6003HDC#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 (0V to V+). Input offset is trimmed on both stages to limit total CMRR-induced shift to ≤1.6mV over full temperature range.
Its folded-cascode second stage and complementary drive output stage deliver rail-to-rail output swing while maintaining stability into 500pF loads. The internal 600kΩ input protection resistors and phase-reversal protection prevent erroneous output polarity when inputs exceed V– by up to 9V - critical for rugged sensor interfacing in industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - supports single-cell Li-ion, two-cell alkaline, and wide industrial rails without level-shifting. |
| Quiescent Current | ≤1.6µA at 5V (–40°C to 125°C) - enables >10-year battery life in always-on IoT sensors. |
| Input Offset Voltage | ≤500µV max (–40°C to 125°C) - ensures <1mV error in 12-bit 2.5V full-scale measurements. |
| Input Bias Current | ≤90pA max (–40°C to 125°C) - minimizes voltage error across high-Z sources like pH electrodes or photodiodes. |
| CMRR | ≥100dB at 1.8V - rejects >100,000:1 common-mode noise in noisy industrial power rails. |
| Capacitive Load Drive | Stable with 500pF - eliminates need for isolation resistors when driving ADC input filters or long PCB traces. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
Pinout & Package
LT6003HDC#TRMPBF is housed in a 4-lead (2mm × 2mm) plastic DFN package with exposed pad connected to V–. The package is 0.75mm nominal height and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Rail-to-rail output capable of sourcing/sinking ≥100µA while staying within 100mV of V+ and 50mV of V–. |
| 2 (V–) | Negative Supply / Ground Reference | Exposed thermal pad (Pin 5) must be soldered to PCB ground plane for thermal and electrical integrity. |
| 3 (+IN) | Non-Inverting Input | High-impedance node (RIN = 10GΩ differential) with phase-reversal protection up to 9V below V–. |
| 4 (–IN) | Inverting Input | Matched to +IN for low input offset current (≤90pA); requires symmetric source impedances to minimize IB-induced errors. |
| 5 (Exposed Pad) | Thermal & Electrical Connection to V– | Required for junction temperature control (TJMAX = 125°C); improves PSRR and reduces thermal drift. |
Key Features

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 2.5µA IQ, 1.2mV VOS max, only rated to 85°C | Limited to commercial/industrial ambient; unsuitable for under-hood or sealed enclosure deployments | Select when cost sensitivity outweighs extended temperature requirement and 1µA savings are non-critical. |
| OPA333AIDBVR | Zero-drift architecture, 12µA IQ, 10µV VOS max, but 125°C rating only for specific variants (OPA333AIDBVT) | Superior DC accuracy at expense of 12× higher supply current - trades battery life for offset stability | Select only if µV-level offset and near-zero drift dominate over micropower constraints in the system BOM. |
Compared with MAX40007AUT+T and OPA333AIDBVR, LT6003HDC#TRMPBF uniquely balances sub-2µA quiescent current, 125°C qualification, and 500µV offset - making it the optimal choice for long-life, high-temperature, precision analog front-ends where every nanoamp counts.

FAQ
What is the maximum guaranteed supply current for LT6003HDC#TRMPBF over its full operating temperature range?
The LT6003HDC#TRMPBF has a maximum guaranteed supply current of 1.6µA at 5V supply voltage across the full –40°C to 125°C operating temperature range, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet (Rev. C, page 4). This value reflects worst-case production testing and ensures reliable micropower operation in high-temp environments.
Does LT6003HDC#TRMPBF support true rail-to-rail input operation down to the negative supply rail?
Yes, LT6003HDC#TRMPBF supports true rail-to-rail input operation from V– to V+, enabled by its dual-input-stage architecture (PNP + NPN pairs). The input common-mode range is guaranteed from 0V to V+ across all supply voltages and temperatures, with phase-reversal protection active even when inputs are driven up to 9V below V– - a key feature confirmed in the Applications Information section (page 13).
What package type and pin configuration does LT6003HDC#TRMPBF use?
LT6003HDC#TRMPBF uses a 4-lead (2mm × 2mm) plastic DFN package (DC package code), with pin 1 = OUT, pin 2 = V–, pin 3 = +IN, pin 4 = –IN, and the exposed thermal pad (pin 5) internally connected to V–. This configuration is explicitly shown in the Pin Configuration diagram on page 5 of the datasheet and confirmed in the Order Information table (page 3).
Can LT6003HDC#TRMPBF drive a 500pF capacitive load without oscillation?
Yes, LT6003HDC#TRMPBF is explicitly characterized and guaranteed to remain stable when driving up to 500pF capacitive loads, as stated in the Features list (page 1) and verified in the Typical Performance Characteristics (Figure G22, page 10). No external compensation or isolation resistor is required - a critical advantage for driving ADC input filters or long PCB traces.
Is LT6003HDC#TRMPBF qualified for automotive under-hood applications?
Yes, LT6003HDC#TRMPBF carries the "H" grade suffix, indicating qualification over the –40°C to 125°C operating temperature range per the Absolute Maximum Ratings table (page 2) and Specified Temperature Range note (page 2, Note 4). This meets AEC-Q100 stress test requirements for under-hood automotive use, and the device is listed in Analog Devices' automotive-grade portfolio.
