Product details
Overview
LT6001IDD#TRPBF 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 with integrated shutdown control. It operates from 1.8V to 16V, draws only 13µA per amplifier at 1.8V, guarantees ≤600µV input offset voltage over –40°C to 85°C, and supports micropower oxygen sensor signal conditioning in battery-powered gas detection systems.
For engineers reviewing the LT6001IDD#TRPBF datasheet, LT6001IDD#TRPBF pinout, LT6001IDD#TRPBF application, or LT6001IDD#TRPBF equivalent, key selection criteria include shutdown current (≤1.5µA), rail-to-rail I/O performance at 1.8V, guaranteed offset drift (≤5µV/°C), and DFN thermal resistance (θJA = 160°C/W) for low-power portable instrumentation.
Technical Context
The LT6001IDD#TRPBF uses a complementary PNP/NPN input stage enabling true rail-to-rail common-mode input range (0V to VS) and output swing within 30mV of both rails. Its folded-cascode second stage and complementary drive generator maintain stability with capacitive loads up to 10nF while delivering 32kHz gain-bandwidth at 1.8V.
Shutdown is controlled via a dedicated SHDN pin referenced to V–; asserting SHDN ≤0.3V places both amplifiers into high-impedance state with total supply current ≤1.5µA and output leakage ≤20nA. The device is fully specified at 1.8V and 5V supplies across –40°C to 85°C, with input bias current polarity reversing between input stages based on common-mode voltage.
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 3.3V/5V rails without level-shifting. |
| Quiescent Current | 13µA per amplifier at 1.8V - Supports >1-year battery life in always-on gas sensors drawing <150µA total system current. |
| Input Offset Voltage | ≤600µV max (–40°C to 85°C) - Ensures <0.5% error in 100mV full-scale oxygen sensor outputs without trimming. |
| Input Offset Drift | ≤5µV/°C - Maintains calibration stability across industrial temperature ranges without active compensation. |
| Output Swing | Within 30mV of rails (no load) - Allows full utilization of 1.8V supply for 0–1.77V analog output range in low-voltage ADC interfaces. |
| Gain Bandwidth | 32kHz at 1.8V - Sufficient for DC–10Hz gas sensing signals while rejecting 50/60Hz interference via filtering. |
| Shutdown Current | ≤1.5µA total - Reduces standby power by >99% versus active mode, critical for intermittent-sampling architectures. |
Pinout & Package
LT6001IDD#TRPBF is housed in a 10-lead 3mm × 3mm plastic DFN package (DD) with exposed pad connected to V–. Thermal resistance θJA = 160°C/W with minimal PCB copper; junction limit is 125°C.
| 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; sources/sinks ≥4mA at 1.8V; high-impedance when SHDN asserted. |
| IN– A | Inverting Input A | Protected by 30kΩ series resistors; phase-reversal immune down to 2V below V–. |
| IN+ A | Non-inverting Input A | Same protection as IN– A; bias current reverses polarity at VCM ≈ VS–1V. |
| SHDN | Shutdown Control | Active-low: ≤0.3V relative to V– disables both amplifiers; floating = active; >1.5V = active. |
| OUT B | Amplifier B Output | Independent rail-to-rail output; shares same shutdown state as OUT A. |
| IN– B | Inverting Input B | Matched to IN– A; enables dual-channel sensor front-end with shared shutdown. |
| IN+ B | Non-inverting Input B | Matched to IN+ A; supports differential or independent signal paths. |
| V– | Negative Supply | Reference for SHDN threshold and exposed pad thermal path; substrate diode to output limits negative overdrive. |
| NC | No Connect | Internal test pin; must be left unconnected per datasheet. |
Key Features

FAQ
What is the maximum supply voltage rating for LT6001IDD#TRPBF?
The absolute maximum total supply voltage (V+ to V–) for LT6001IDD#TRPBF is 18V. Operation beyond this risks permanent damage. The device is fully specified from 1.8V to 16V, with performance guaranteed across –40°C to 85°C at both 1.8V and 5V supplies. Exposed pad thermal design must accommodate power dissipation at higher voltages.
Does LT6001IDD#TRPBF support true rail-to-rail input at 1.8V supply?
Yes, LT6001IDD#TRPBF supports rail-to-rail input common-mode range (0V to VS) at 1.8V supply. Its dual PNP/NPN input stage ensures continuous operation across the full range, with input offset voltage guaranteed ≤600µV and CMRR ≥82dB at 1.8V. This enables direct connection to sensors whose output spans the entire supply rail.
How does the shutdown function behave on LT6001IDD#TRPBF?
LT6001IDD#TRPBF enters shutdown when the SHDN pin voltage is ≤0.3V relative to V–, reducing total supply current to ≤1.5µA and placing both outputs in high-impedance state with ≤20nA leakage. SHDN must be actively driven low; leaving it floating may cause unintended shutdown due to parasitic leakage. For normal operation, tie SHDN to V+.
Can LT6001IDD#TRPBF drive capacitive loads without oscillation?
LT6001IDD#TRPBF is stable with capacitive loads up to 10nF when configured as a unity-gain buffer, as verified in typical performance curves. For loads >100pF, a series resistor (≥100Ω) between output and capacitance is recommended to maintain phase margin >60°. The device's internal compensation eliminates need for external compensation networks in most sensor interface applications.
What is the thermal performance of the DD package used by LT6001IDD#TRPBF?
The 10-lead DFN (DD) package of LT6001IDD#TRPBF has θJA = 160°C/W with minimal PCB copper, and a maximum junction temperature of 125°C. The exposed pad is internally connected to V– and must be soldered to a thermal pad on the PCB. Adding ≥2cm² of inner-layer copper pour reduces θJA by ~30%, critical for sustained operation near 16V supply in enclosed enclosures.
