Product details
Overview
LT6002IDHC#PBF from Analog Devices (formerly Linear Technology) is a quad precision rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage signal conditioning in battery- or solar-powered systems. It operates from 1.8V to 16V, draws only 13–16µA per amplifier, features ≤900µV max input offset voltage (0°C to 70°C), and delivers rail-to-rail output swing within 30mV of both rails - enabling accurate sensing in gas detection and portable instrumentation.
For engineers reviewing the LT6002IDHC#PBF datasheet, LT6002IDHC#PBF pinout, LT6002IDHC#PBF application, or LT6002IDHC#PBF equivalent, key selection criteria include guaranteed 1.8V operation, industrial temperature range (–40°C to 85°C), DFN-16 package thermal performance (θJA = 160°C/W), and verified shutdown capability with <1.5µA total quiescent current.
Technical Context
The LT6002IDHC#PBF implements dual complementary input stages (PNP and NPN) to achieve true rail-to-rail common-mode input range (0V to VS) while maintaining low offset drift (2–5µV/°C). Its folded-cascode second stage and complementary drive output stage enable stable unity-gain operation with 32–50kHz gain-bandwidth product and 7–15V/ms slew rate across supply voltages.
Designed specifically for micropower sensor front-ends, it integrates phase-reversal protection, 30kΩ input series resistors, and robust start-up behavior - drawing controlled current (<24µA per amplifier) even during output saturation at either rail, unlike many competitive micropower op amps.
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 (0.9–1.4V × 2), or 3.3V/5V rails without regulation. |
| Quiescent Current per Amp | 13–16µA (typ/max) - supports multi-year battery life in always-on gas sensors and portable meters. |
| Input Offset Voltage | ≤900µV max (0°C to 70°C), ≤1100µV max (–40°C to 85°C) - ensures sub-mV DC accuracy in low-gain transducer interfaces. |
| Input Common-Mode Range | 0V to VS - allows direct sensing of signals referenced to ground or supply rail, e.g., oxygen sensor bridge outputs. |
| Output Swing (No Load) | Within 30mV of V+ and V– - preserves dynamic range in 1.8V systems where headroom is critical. |
| Gain Bandwidth Product | 32–50kHz - sufficient for anti-aliasing, active filtering, and DC-stable sensor amplification up to ~10kHz. |
| Shutdown Current | ≤1.5µA total (both supplies) - reduces system standby power by >90% when amplifiers are idle. |
Pinout & Package
LT6002IDHC#PBF is housed in a 16-lead 5mm × 3mm DFN package (DHC) with exposed thermal pad connected to V– (Pin 13). The package supports high-density PCB layouts and offers θJA = 160°C/W with minimal copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 14, 15, 16 | OUT A, IN– A, IN+ A, OUT C, IN– C, IN+ C | Amplifier A and C output and differential inputs - fully independent channels for multi-sensor conditioning. |
| 4, 13 | V+, V– | Main supply rails - require local 0.01µF ceramic bypassing within 25mm; exposed pad must be soldered to ground plane for thermal stability. |
| 5, 6, 7, 10, 11, 12 | IN+ B, IN– B, OUT B, IN+ D, IN– D, OUT D | Amplifier B and D output and differential inputs - identical specs to A/C; all four amps share same V+/V– and operate simultaneously. |
| 8, 9 | NC | No-connect pins - must remain unconnected; no internal function or test access. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8V supply range - eliminates level-shifting circuitry in low-voltage sensor nodes. |
| 1.8V minimum supply | Supports direct interface with energy-harvesting sources (e.g., solar cells, thermoelectric generators) without boost converters. |
| Industrial temperature grade (–40°C to 85°C) | Guaranteed parametric performance across automotive cabin, outdoor instrumentation, and industrial control environments. |
| Phase reversal protection | Prevents erroneous output polarity when inputs exceed V– by up to 2V - critical for robustness in unregulated sensor interfaces. |
| Controlled start-up current | Draws <24µA per amplifier even during output saturation - avoids brown-out in weak-battery or high-impedance supply scenarios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02µV/°C offset drift vs. LT6002's 2–5µV/°C; higher 350nA input bias current; 17µA supply current. | Better long-term DC stability in temperature-cycling environments; less suitable for ultra-low-IB pH or ion-selective electrodes. | Select OPA2333AIDR when microvolt-level drift over time is critical and supply current budget allows +4µA per amp. |
| MCP6V81-E/MS | Zero-drift; 1.6µA supply current; 1.6V min supply; only dual-channel; MSOP-8 package (no thermal pad). | Lower power than LT6002 but lacks quad configuration and DFN thermal performance; limited to <85°C operation. | Select MCP6V81-E/MS for space-constrained dual-channel designs where 1.6µA is mandatory and thermal load is light. |
Compared with OPA2333AIDR and MCP6V81-E/MS, the LT6002IDHC#PBF uniquely balances quad-channel integration, industrial temperature rating, DFN thermal efficiency, and proven rail-to-rail performance at 1.8V - making it optimal for multi-sensor battery-powered systems requiring consistent channel matching and layout scalability.

FAQ
What is the maximum input common-mode voltage range for LT6002IDHC#PBF?
The LT6002IDHC#PBF supports a rail-to-rail input common-mode voltage range from V– to V+, including both supply rails. At 1.8V supply, this means 0V to 1.8V is fully functional - verified across –40°C to 85°C. This enables direct interfacing with sensors whose outputs swing to ground or supply, such as bridge-based gas sensors.
Does LT6002IDHC#PBF include a shutdown feature?
No, the LT6002IDHC#PBF does not include a shutdown feature. Shutdown is only available on the LT6000 (single) and LT6001DD (dual 10-lead DFN) variants. The LT6002 is offered in GN (SSOP) and DHC (DFN) packages without SHDN functionality - confirmed by absence of SHDN pin in DHC pinout and omission from LT6002-specific electrical characteristics tables.
What is the typical input bias current of LT6002IDHC#PBF and how does it vary with common-mode voltage?
The LT6002IDHC#PBF exhibits input bias current that varies with input common-mode voltage due to its dual PNP/NPN input stage. At VCM = VS/2, typical IB is –2nA; it flows out of inputs in PNP region (low VCM) and into inputs in NPN region (high VCM). This bipolar behavior is documented in Figure 60012 G07 and requires matched source impedances to minimize offset error.
Can LT6002IDHC#PBF drive capacitive loads, and what is the recommended compensation?
Yes, the LT6002IDHC#PBF can drive moderate capacitive loads. Figure 60012 G23 shows <5% overshoot with 100pF load at AV = 1. For loads >100pF, a series resistor (10–100Ω) between amplifier output and capacitor is recommended to isolate the reactive load and maintain phase margin - consistent with standard micropower op amp stability practices.
What is the thermal resistance (θJA) of the LT6002IDHC#PBF DFN package, and how is it affected by PCB layout?
The LT6002IDHC#PBF DFN package has θJA = 160°C/W under standard JEDEC test conditions (minimal copper). With expanded thermal pad copper area across multiple PCB layers, θJA can be reduced significantly - as noted in Note 2 of the datasheet. The exposed pad (Pin 17) must be soldered to a solid ground plane to realize thermal benefit and ensure reliable operation at full rated current.
