Product details
Overview
LT6001IDD#PBF from Analog Devices (formerly Linear Technology) is a dual precision rail-to-rail input/output operational amplifier in a 10-lead 3mm × 3mm DFN package, featuring 16µA max supply current per amplifier, 600µV max input offset voltage, and operation down to 1.8V supply. It integrates shutdown functionality with 1.5µA max total quiescent current in shutdown mode and is optimized for gas sensing, portable instrumentation, and battery-powered systems.
For engineers reviewing the LT6001IDD#PBF datasheet, LT6001IDD#PBF pinout, LT6001IDD#PBF application, or LT6001IDD#PBF equivalent, key selection criteria include verified shutdown behavior, guaranteed 1.8V operation, rail-to-rail swing within 30mV of rails, low 75nV/√Hz input voltage noise, and confirmed DFN-10 thermal performance (θJA = 160°C/W).
Technical Context
The LT6001IDD#PBF employs a complementary PNP/NPN input stage enabling true rail-to-rail common-mode input range (0V to VS) and output swing (within 30mV of V+/V−). Its folded-cascode second stage and complementary drive generator maintain stability with capacitive loads up to 10nF while delivering 32kHz gain-bandwidth product at 1.8V.
Shutdown is controlled via a dedicated SHDN pin referenced to V−, with guaranteed activation below 0.3V and release above 1.5V (1.8V supply), enabling precise power gating in micropower sensor front-ends without external logic. Input offset drift is specified at 2–5µV/°C over –40°C to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 16V - Enables direct operation from single-cell Li-ion (3.0–4.2V), NiMH (1.2V×2), or 1.8V logic rails without level-shifting. |
| Quiescent Current | 13–16µA per amplifier - Supports >1-year battery life in always-on CO or O2 sensors drawing <150µA total system current. |
| Input Offset Voltage | 600µV max (–40°C to 85°C) - Ensures <0.5% error in 100mV full-scale sensor outputs without trimming. |
| Input/Output Swing | Rail-to-rail - Delivers full dynamic range from 0V to 1.8V supply, critical for low-voltage ADC interfacing. |
| Gain Bandwidth | 32kHz at 1.8V - Sufficient for DC–10kHz sensor signal conditioning including active filtering and transimpedance amplification. |
| Shutdown Current | 1.5µA max total - Reduces standby power by >90% vs active mode, enabling duty-cycled measurement architectures. |
| Input Voltage Noise | 75nV/√Hz at 1kHz - Preserves signal integrity in high-gain (≥100×) electrochemical sensor interfaces. |
Pinout & Package
LT6001IDD#PBF is housed in a 10-lead 3mm × 3mm plastic DFN package (DD) with exposed pad connected to V− for thermal and electrical grounding. Package thermal resistance is θJA = 160°C/W with minimal PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive Supply | Accepts 1.8V–16V; requires 0.01µF bypass capacitor within 25mm for stability. |
| OUT A | Amplifier A Output | Rail-to-rail capable; sinks 4mA at 1.8V, sources 10mA at 5V. |
| IN− A | Inverting Input A | Protected by 30kΩ series resistors; supports inputs down to 2V below V−. |
| IN+ A | Non-inverting Input A | Same protection as IN− A; bias current reverses polarity across VCM range. |
| SHDN | Shutdown Control | Active-low: ≤0.3V relative to V− disables both amplifiers and places outputs in high-Z state. |
| OUT B | Amplifier B Output | Independent output; shares same shutdown control and supply pins as Channel A. |
| IN− B | Inverting Input B | Duplicate of IN− A; enables dual-channel sensor signal conditioning on single footprint. |
| IN+ B | Non-inverting Input B | Duplicate of IN+ A; allows simultaneous processing of reference and sense signals. |
| V− | Negative Supply / Ground | Reference for SHDN threshold and exposed pad thermal path; must be low-impedance. |
| NC | No Connect | Internal die pad with no electrical function; left unconnected per datasheet. |
Key Features

FAQ
What is the maximum operating temperature range for the LT6001IDD#PBF?
The LT6001IDD#PBF is specified for continuous operation from –40°C to +85°C. This industrial temperature grade is validated across all key parameters including input offset voltage (≤600µV), supply current (≤16µA), and shutdown leakage (≤20nA), making LT6001IDD#PBF suitable for outdoor environmental sensors and automotive cabin air quality modules.
Does the LT6001IDD#PBF require external components for stable shutdown operation?
No external components are required for basic shutdown control of the LT6001IDD#PBF. Driving the SHDN pin to ≤0.3V relative to V− reliably disables both amplifiers and places outputs in high-impedance state. However, a pull-up resistor to V+ is recommended if driven by open-drain GPIO to prevent floating-state shutdown activation due to leakage currents exceeding 1µA.
Can the LT6001IDD#PBF drive capacitive loads without oscillation?
Yes, the LT6001IDD#PBF maintains stability with capacitive loads up to 10nF in unity-gain configuration, as confirmed by phase margin >60° across temperature and supply voltage. For loads >100pF, a 10Ω series resistor at the output is recommended to isolate capacitance from the amplifier's output stage, preserving step response fidelity in sensor signal paths.
How does the LT6001IDD#PBF handle input voltages beyond the supply rails?
The LT6001IDD#PBF incorporates 30kΩ series input resistors and phase reversal protection, allowing inputs to safely extend 2V below V− without output inversion. Inputs driven above V+ must be current-limited to ≤10mA to prevent damage to internal ESD structures. This robustness enables direct connection to unregulated sensor outputs in industrial fieldbus applications.
Is the exposed thermal pad on the LT6001IDD#PBF package required to be soldered?
Yes, the exposed pad on the LT6001IDD#PBF DFN-10 package must be soldered to a PCB thermal plane connected to V−. This connection is essential to achieve the specified θJA = 160°C/W and prevent junction temperature exceedance during sustained 16µA operation. Omitting this connection degrades thermal performance by >40%, risking parametric shift at elevated ambient temperatures.
