Product details
Overview
LT6003HDC#TRPBF 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, 2µV/°C drift, and drives 500pF capacitive loads - enabling high-accuracy signal conditioning in portable gas monitors and low-voltage sensor interfaces.
For engineers reviewing the LT6003HDC#TRPBF datasheet, LT6003HDC#TRPBF pinout, LT6003HDC#TRPBF application, or LT6003HDC#TRPBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, 2mm × 2mm DFN package with exposed V– pad, rail-to-rail CMVR (0V to V+), and ultralow supply current stability across temperature and supply voltage.
Technical Context
The LT6003HDC#TRPBF uses 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.
Offset voltage is trimmed on both input stages to limit total CMRR-induced shift to ≤1.6mV over full VCM range. Input bias current remains ≤90pA (typ. 7pA) when VCM stays ≥0.3V from either rail, and PSRR (≥76dB) and CMRR (≥78dB) are specified across –40°C to 125°C for automotive and industrial use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - supports single-cell Li-ion, 2xAA, 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 sensor nodes. |
| Input Offset Voltage | ≤1.6mV max at –40°C to 125°C - ensures <0.1% error in 1.6V full-scale 12-bit ADC front-ends. |
| Offset Drift | ≤3µV/°C max - maintains calibration stability across automotive under-hood temperatures. |
| Input Bias Current | ≤12nA max at –40°C to 125°C - minimizes voltage error with high-impedance pH or gas sensor electrodes. |
| Capacitive Load Drive | 500pF - allows direct connection to ADC input caps or long PCB traces without external isolation. |
| CMRR / PSRR | ≥78dB / ≥76dB - rejects supply noise and common-mode interference in noisy industrial environments. |
Pinout & Package
The LT6003HDC#TRPBF is housed in a 4-lead (2mm × 2mm) plastic DFN package with exposed pad connected to V–. The package is RoHS-compliant, halogen-free, and rated for TJ ≤ 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Rail-to-rail swing: ≤275mV from V– and ≤400mV from V+ at 100µA load, –40°C to 125°C. |
| 2 - V– | Negative supply / reference | Exposed thermal pad must be soldered to PCB ground plane for thermal and electrical integrity. |
| 3 - +IN | Non-inverting input | High-impedance (≥2TΩ common-mode), supports CMVR from V– to V+ with phase reversal protection. |
| 4 - –IN | Inverting input | Matched to +IN; 6pF input capacitance limits bandwidth with high-Z sources unless guarded. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with input common-mode voltage from V– to V+ and output swing within 275mV of V– and 400mV of V+ at 100µA, enabling single-supply 0–1.6V sensor interfacing. |
| Ultralow quiescent current | 1.6µA max over –40°C to 125°C ensures stable power budget in energy-harvesting systems with µW-level sources. |

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+ | Higher 2.5µA IS, 1.25mV VOS max, same 2mm × 2mm package but no exposed pad. | Limited to commercial temp (0°C to 70°C); unsuitable for automotive or extended industrial use. | Select when cost sensitivity outweighs temperature range and thermal performance requirements. |
| OPA333AIDBVR | Zero-drift architecture, 12µV VOS max, but 17µA IS - 10× higher than LT6003HDC#TRPBF. | Superior DC accuracy but incompatible with µA-level power budgets in energy-harvesting designs. | Select only when sub-µV offset stability is mandatory and supply current >10µA is acceptable. |
Compared with MAX44260ASA+ and OPA333AIDBVR, the LT6003HDC#TRPBF uniquely balances ultralow supply current (≤1.6µA), extended temperature range (–40°C to 125°C), and rail-to-rail operation in a thermally enhanced 2mm × 2mm DFN - making it optimal for battery longevity and harsh-environment reliability where zero-drift isn't required.

FAQ
What is the maximum operating temperature range for the LT6003HDC#TRPBF?
The LT6003HDC#TRPBF is rated for continuous operation from –40°C to 125°C, with all electrical specifications fully guaranteed across this extended industrial and automotive temperature range. This H-grade qualification distinguishes it from C- and I-grade variants and makes the LT6003HDC#TRPBF suitable for under-hood automotive, industrial control, and outdoor environmental monitoring applications where thermal resilience is critical.
Does the LT6003HDC#TRPBF require external compensation for stability?
No, the LT6003HDC#TRPBF is unity-gain stable and does not require external compensation. It is explicitly characterized to drive ≥500pF capacitive loads without oscillation or excessive overshoot, as verified in the manufacturer's Typical Performance Characteristics (Figure G22). This eliminates the need for series isolation resistors or feedback capacitor tuning in ADC driver or filter applications.
How is the exposed pad on the LT6003HDC#TRPBF DFN package connected?
The exposed pad on the LT6003HDC#TRPBF is internally connected to the V– terminal and must be soldered to a PCB copper pour tied to the system ground or negative supply plane. Per the datasheet (DC package drawing), this connection is mandatory for thermal dissipation and electrical performance - failure to solder the pad may result in junction temperature exceeding 125°C and degraded parametric performance.
Can the LT6003HDC#TRPBF operate from a 1.6V single supply?
Yes, the LT6003HDC#TRPBF is fully specified and functional down to 1.6V total supply voltage, with quiescent current, input offset voltage, and rail-to-rail input/output behavior guaranteed at this minimum. Its ability to operate from 1.6V enables direct compatibility with single alkaline or NiMH cells and extends runtime in energy-constrained IoT edge nodes where supply voltage sags during discharge.
What is the input bias current behavior near the supply rails?
The LT6003HDC#TRPBF input bias current remains ≤90pA when the input common-mode voltage (VCM) stays ≥0.3V from either rail. As VCM approaches V–, IB increases due to PNP tail-current dominance; near V+, IB rises into the nA range as cancellation circuitry saturates. For precision applications, keep VCM ≥0.3V from rails or match source impedances to minimize offset errors caused by IB mismatch.
