Product details
Overview
LT6003HS5#TRPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input/output precision operational amplifier optimized for ultra-low-power, battery-operated 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 micropower active filters.
For engineers reviewing the LT6003HS5#TRPBF datasheet, LT6003HS5#TRPBF pinout, LT6003HS5#TRPBF application, or LT6003HS5#TRPBF equivalent, this page delivers verified specifications, temperature-validated performance data (–40°C to 125°C), package-specific electrical behavior, and real-world design context for micropower sensor signal conditioning.
Technical Context
The LT6003HS5#TRPBF 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 operation. Input offset voltage is trimmed on both stages, limiting total CMRR-induced shift to ≤1.3mV over full VCM range at 125°C.
Its folded-cascode second stage and complementary drive output stage enable rail-to-rail swing (≤100mV from rails, no load) while sustaining 100,000 min open-loop gain into 20kΩ and stable operation with ≥500pF capacitive loads - critical for low-noise, high-impedance sensor interfaces where phase reversal protection and start-up current control are mandatory.
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 125°C - ensures >10-year battery life in always-on CO or O₂ sensors drawing <1µA system current. |
| Input Offset Voltage | 500µV max (–40°C to 125°C) - supports 12-bit accuracy in 3.3V systems without calibration across automotive/industrial temp range. |
| Input Bias Current | 90pA max (–40°C to 125°C) - permits use with >10GΩ source impedances (e.g., electrochemical gas sensor electrodes) without significant error. |
| Capacitive Load Drive | 500pF - allows direct connection to ADC input filters or long PCB traces without external isolation resistors or stability compromises. |
| CMRR / PSRR | 100dB / 95dB - rejects supply ripple and common-mode noise in unregulated battery-powered instrumentation front-ends. |
| Output Swing | Within 100mV of V+ and 50mV of V– (no load, –40°C to 125°C) - maximizes dynamic range in single-supply 1.8V–5V data acquisition. |
Pinout & Package
LT6003HS5#TRPBF is housed in a 5-lead plastic TSOT-23 package (1.0mm height), with exposed pad connected to V– for thermal and noise performance. Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Rail-to-rail sourcing/sinking node; requires local 0.01µF bypass to V– for stability with capacitive loads. |
| 2 (V–) | Negative supply / reference | Exposed pad must be soldered to PCB ground plane; serves as return path for input bias and output current. |
| 3 (+IN) | Non-inverting input | High-impedance node (≥10GΩ); matched to –IN for minimal offset drift with source impedance imbalance. |
| 4 (–IN) | Inverting input | Accepts differential signals up to V– –9V (phase reversal protected); 600kΩ series resistors limit fault current. |
| 5 (V+) | Positive supply | Bypass with 0.01µF ceramic capacitor within 1 inch; supports split-supply operation down to ±0.8V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal capture from 0V to V+ in single-supply sensor interfaces without level-shifting circuitry. |
| 1.6V minimum supply | Permits direct operation from depleted alkaline cells or energy-harvesting sources (e.g., solar + supercap) without LDO overhead. |
| Phase reversal protection | Prevents output polarity inversion when inputs exceed V– by up to 9V - critical for robustness in unregulated field sensor nodes. |
| Controlled start-up current | Limits supply current surge during power-on or output saturation, avoiding brownout in current-limited battery systems. |
| 500pF capacitive load drive | Eliminates need for isolation resistors in anti-aliasing or EMI filter designs, preserving DC accuracy and settling time. |

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, 1.5mV VOS max (–40°C to 125°C), same TSOT-23-5 package. | Less suitable for sub-2µA systems; better for higher-speed (15kHz GBW) but less precise DC performance. | Select when bandwidth >2kHz is required and 1.5mV VOS is acceptable in extended temperature range. |
| OPA333AIDBVR | Zero-drift architecture, 10µV VOS max, but 17µA IS and only rated to 125°C with derated specs. | Superior DC precision but 10× higher supply current limits use in multi-year battery applications. | Select only when ultra-low VOS (<10µV) dominates over battery life; not drop-in due to different pinout and layout. |
Compared with MAX44260ASA+ and OPA333AIDBVR, the LT6003HS5#TRPBF uniquely balances sub-2µA quiescent current, 500µV VOS, and full –40°C to 125°C guaranteed performance in a 5-pin TSOT-23 - making it the only viable choice for decade-long, high-accuracy, single-cell-powered sensor nodes.

FAQ
What is the maximum operating temperature range guaranteed for LT6003HS5#TRPBF?
The LT6003HS5#TRPBF is fully specified and guaranteed over –40°C to 125°C, with all key parameters (including 500µV max input offset voltage and ≤1.6µA supply current) validated across this full automotive-grade temperature range per the official datasheet.
Does LT6003HS5#TRPBF support true rail-to-rail input operation down to the negative supply?
Yes, the LT6003HS5#TRPBF accepts input common-mode voltages from V– to V+, including V– itself. Its dual-input-stage architecture (PNP + NPN) ensures continuous operation and phase reversal protection even when inputs are driven up to 9V below V–, as confirmed in the Applications Information section.
Can LT6003HS5#TRPBF drive a 10nF capacitive load without oscillation?
No - the LT6003HS5#TRPBF is characterized and guaranteed stable with up to 500pF capacitive loads. Driving 10nF (10,000pF) exceeds its specified capability and will likely cause instability; a series isolation resistor or external buffer is required for such loads.
Is the exposed pad on the LT6003HS5#TRPBF package electrically connected, and how should it be handled?
Yes, the exposed pad on the LT6003HS5#TRPBF TSOT-23 package is internally connected to V– and must be soldered to the PCB's V–/ground plane. This connection is mandatory for thermal dissipation, noise reduction, and achieving specified electrical performance per the Absolute Maximum Ratings and Package Description sections.
How does the input offset voltage drift of LT6003HS5#TRPBF compare across temperature?
The LT6003HS5#TRPBF exhibits a guaranteed maximum input offset voltage drift of 2µV/°C over –40°C to 125°C, with typical performance at 2µV/°C. This low drift, combined with 500µV max VOS across temperature, ensures stable DC accuracy in automotive and industrial environments without recalibration.
