Product details
Overview
LT6003CS5#TRPBF 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, 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 LT6003CS5#TRPBF datasheet, LT6003CS5#TRPBF pinout, LT6003CS5#TRPBF application, or LT6003CS5#TRPBF equivalent, key selection criteria include guaranteed 1.6V minimum supply operation, rail-to-rail I/O performance across –40°C to 85°C, ultralow supply current stability over temperature, and compatibility with 5-lead TSOT-23 PCB footprints.
Technical Context
The LT6003CS5#TRPBF 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. Input offset voltage is trimmed on both stages to limit CMRR-induced shift to ≤1.3mV over full VCM range.
Its folded-cascode second stage and complementary drive output stage deliver rail-to-rail swing (≤100mV from rails, no load) while maintaining stability with ≥500pF capacitive loads. PSRR (≥95dB) and CMRR (≥100dB) are specified down to 1.8V supply, supporting precision DC-coupled sensing in low-voltage industrial and automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - enables direct operation from single-cell Li-ion (3.0–4.2V), alkaline (1.5V × 2), or energy-harvesting sources without regulation. |
| Quiescent Current | ≤1.6µA at 5V, –40°C to 85°C - ensures >10-year battery life in always-on CO or O₂ sensor nodes powered by CR2032 cells. |
| Input Offset Voltage | 500µV max (0°C to 70°C), 950µV max (–40°C to 85°C) - supports 12-bit accuracy in 3.3V ADC front-ends without trimming. |
| Input Bias Current | 90pA max - allows use with high-impedance pH or electrochemical sensor electrodes (>100MΩ source impedance) without significant error. |
| Capacitive Load Drive | 500pF - permits direct connection to long PCB traces, EMI filters, or ADC input capacitance without external isolation resistors. |
| CMRR / PSRR | 100dB / 95dB min at 1.8V - rejects supply ripple and common-mode noise in unregulated battery systems with minimal gain error. |
| Operating Temperature | –40°C to 85°C (I-grade) - qualified for industrial and automotive cabin ambient environments. |
Pinout & Package
LT6003CS5#TRPBF is housed in a 5-lead plastic TSOT-23 package (1.0mm height), with exposed pad connected to V– for thermal and electrical integrity. Pin 1 is marked with a dot; orientation follows JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Rail-to-rail sourcing/sinking output capable of driving 500pF directly; connects to sensor buffer or ADC input. |
| 2 (V–) | Negative Supply Rail | Reference for all internal circuitry; exposed pad must be soldered to PCB ground plane for thermal dissipation and noise immunity. |
| 3 (+IN) | Non-Inverting Input | High-impedance node (10GΩ differential) for reference or sensor signal; requires matched trace impedance to –IN for optimal CMRR. |
| 4 (–IN) | Inverting Input | High-impedance feedback node; bias current cancellation active when VCM > V– + 0.3V and < V+ – 0.3V. |
| 5 (V+) | Positive Supply Rail | Power input requiring local 0.01µF ceramic bypass within 1 inch; supports unregulated 1.6–16V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow Supply Current | 1µA/amp max enables multi-year operation on coin cells in wireless sensor transmitters. |
| Rail-to-Rail Input/Output | Full V– to V+ input range and ≤100mV from rails output swing maximize dynamic range in 1.8V–3.3V systems. |
| Low Input Offset Drift | 2µV/°C typical drift ensures stable calibration over industrial temperature ranges without software compensation. |
| Phase Reversal Protection | Internal circuitry prevents output polarity inversion when inputs exceed V– by up to 9V - critical for robustness in noisy industrial sensors. |
| Stable with Heavy Capacitive Loads | Guaranteed stability with 500pF output capacitance eliminates need for isolation resistors in anti-alias filter designs. |

FAQ
What is the minimum supply voltage specification for LT6003CS5#TRPBF?
The LT6003CS5#TRPBF is guaranteed to operate down to 1.6V supply voltage, with specifications validated at 1.8V, 5V, and ±8V. Its PSRR remains ≥80dB even at 1.6V, ensuring reliable functionality in single-cell lithium or alkaline battery systems where voltage sags below 2.0V during discharge.
Does LT6003CS5#TRPBF support rail-to-rail input and output simultaneously?
Yes, the LT6003CS5#TRPBF supports true rail-to-rail input (V– to V+) and output (within 100mV of V+ and 50mV of V–, no load) across its full operating temperature range. This is enabled by its dual-input-stage architecture and complementary drive output stage, allowing full utilization of supply headroom in 1.8V and 3.3V systems.
How does LT6003CS5#TRPBF handle input overvoltage conditions?
The LT6003CS5#TRPBF incorporates phase reversal protection and 600kΩ series input resistors that limit input current to safe levels. It withstands inputs up to 9V below V– without polarity inversion, and input current is restricted to <10mA when driven above V+, meeting robustness requirements for industrial sensor interfaces.
What is the maximum capacitive load LT6003CS5#TRPBF can drive without instability?
The LT6003CS5#TRPBF is tested and guaranteed stable with up to 500pF capacitive load at the output, a key differentiator for sensor interface and anti-alias filter applications. This eliminates the need for external isolation resistors in most configurations, simplifying layout and preserving signal integrity in high-impedance analog paths.
Is LT6003CS5#TRPBF pin-compatible with other members of the LT600x family?
No - the LT6003CS5#TRPBF (5-pin TSOT-23) is not pin-compatible with LT6004 (dual) or LT6005 (quad) variants, which use 8-pin MSOP/DFN and 16-pin SSOP/DFN packages respectively. However, its TSOT-23 footprint matches industry-standard 5-lead op amp layouts, enabling drop-in replacement for similar single-channel micropower amplifiers.
