Product details
Overview
LT6005HDHC#PBF from Analog Devices (formerly Linear Technology) is a quad micropower rail-to-rail input/output operational amplifier optimized for battery-powered and ultra-low-power systems. It operates from 1.6V to 16V supply, draws ≤1.6µA per amplifier at 5V, features 500µV max input offset voltage, 2µV/°C drift, 90pA max input bias current, and drives 500pF capacitive loads - enabling precision signal conditioning in portable gas monitors and solar-powered sensor nodes.
For engineers reviewing the LT6005HDHC#PBF datasheet, LT6005HDHC#PBF pinout, LT6005HDHC#PBF application, or LT6005HDHC#PBF equivalent, this page delivers verified electrical specs, thermal-grade package details (–40°C to 125°C), real-world capacitive load handling data, and direct alternatives for low-voltage, high-precision analog front-ends.
Technical Context
The LT6005HDHC#PBF implements a dual-input-stage architecture: a PNP pair active from V– to ~0.9V below V+, and an NPN pair engaging near V+ to ensure true rail-to-rail common-mode input range. Its folded-cascode second stage and complementary drive output stage enable rail-to-rail swing while maintaining stability with ≥500pF loads.
Offset trimming is applied independently to both input stages, limiting total input offset voltage shift across the full common-mode range to ≤1.8mV (at –40°C to 125°C), and CMRR remains ≥78dB over temperature - critical for DC-coupled sensor interfaces where common-mode rejection directly impacts measurement accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - supports single-cell Li-ion, two-cell alkaline, and industrial 12V rails without level-shifting. |
| Quiescent Current | ≤1.6µA per amplifier at 5V - enables >10-year battery life in always-on environmental sensors. |
| Input Offset Voltage | ≤1.8mV max at –40°C to 125°C - ensures <0.1% gain error in 10-bit ADC front-ends with 1kΩ source impedance. |
| Input Bias Current | ≤90pA max - allows use with >100MΩ sensor elements (e.g., electrochemical gas cells) without significant offset drift. |
| Capacitive Load Drive | 500pF stable - eliminates need for isolation resistors when driving ADC input filters or long PCB traces. |
| CMRR | ≥78dB at –40°C to 125°C - rejects power-supply ripple and EMI coupling in noisy industrial environments. |
| PSRR | ≥76dB - maintains precision under varying battery voltage or unregulated DC supplies. |
Pinout & Package
LT6005HDHC#PBF is housed in a 16-lead (5mm × 3mm) plastic DFN package with exposed pad connected to V–. The package supports high-density layouts and enhanced thermal performance (θJA = 160°C/W) for automotive under-hood applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Rail-to-rail swing: within 100mV of V+ and 50mV of V– at no load, enabling full-scale utilization of 1.8V ADCs. |
| 2 (–IN A) | Inverting input A | High-impedance node (RIN ≥10GΩ); matched to +IN A for minimal input offset due to source imbalance. |
| 3 (+IN A) | Non-inverting input A | Accepts signals from V– to V+; phase-reversal protected up to 9V below V–. |
| 4 (V–) | Negative supply | Exposed pad (Pin 17) must be soldered to PCB ground plane for thermal and electrical integrity. |
| 5 (+IN B) | Non-inverting input B | Independent channel; identical specs to Channel A - supports differential sensing or multi-sensor buffering. |
| 6 (–IN B) | Inverting input B | Electrically isolated from other channels; no crosstalk specified - suitable for simultaneous multi-channel acquisition. |
| 7 (OUT B) | Amplifier B output | Same drive capability as OUT A; can sink/source ≥5mA at 1.8V supply for active filter stages. |
| 8 (NC) | No connect | Not internally bonded - leave unconnected; no impact on performance or reliability. |
| 9 (OUT C) | Amplifier C output | Third independent output; enables 3-wire RTD excitation + reference + sense amplification in one IC. |

| 11 (+IN C) | Non-inverting input C | Valid for common-mode voltages up to V+ - allows direct connection to high-side current sense points. |
| 12 (V+) | Positive supply | Requires local 0.01µF ceramic bypass capacitor within 1 inch; optional 4.7µF bulk cap for heavy transient loads. |
| 13 (+IN D) | Non-inverting input D | Enables fourth independent signal path - e.g., temperature compensation channel in multi-parameter gas analyzers. |
| 14 (–IN D) | Inverting input D | Matched input characteristics ensure consistent offset and drift behavior across all four amplifiers. |
| 15 (OUT D) | Amplifier D output | Full rail-to-rail operation supports low-voltage reference buffer or DAC output amplification. |
| 16 (NC) | No connect | Unused pad - no internal connection; may be left floating or tied to V– for mechanical stability. |
| 17 (Exposed Pad) | V– thermal/electrical connection | Must be soldered to PCB copper pour tied to V– net; improves thermal dissipation and reduces noise coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV914IQ4T | Higher supply current (38µA/amplifier), wider offset range (3mV max), no guaranteed 125°C operation | Targeted at consumer-grade portable devices, not automotive or industrial harsh environments | Select when cost sensitivity outweighs ultra-low-power and extended temperature requirements |
| OPA2333PWR | Zero-drift architecture (0.02µV/°C drift), higher supply current (17µA/amplifier), 1.8V min supply | Better DC precision for high-resolution data loggers; less suitable for sub-2V battery operation | Select when microvolt-level offset stability dominates over battery life and low-voltage operation |
Compared with TSV914IQ4T and OPA2333PWR, LT6005HDHC#PBF uniquely balances sub-2µA quiescent current, 1.6V operation, and –40°C to 125°C qualification - making it the only option for long-life, wide-temperature, single-cell-powered sensor systems requiring <1mV offset.

FAQ
What is the maximum operating temperature range for LT6005HDHC#PBF?
The LT6005HDHC#PBF is rated for continuous operation from –40°C to 125°C, with full electrical specifications guaranteed across this range. This H-grade qualification makes LT6005HDHC#PBF suitable for under-hood automotive, industrial control cabinets, and outdoor environmental monitoring equipment where ambient temperatures exceed 85°C.
Can LT6005HDHC#PBF operate from a single 1.6V supply?
Yes, LT6005HDHC#PBF is fully specified and functional down to 1.6V total supply voltage. At 1.6V, it maintains rail-to-rail input common-mode range (V– to V+), output swing within 120mV of each rail, and quiescent current ≤1.4µA per amplifier - enabling direct interface with single alkaline or lithium-thionyl chloride cells.
Does LT6005HDHC#PBF require external compensation for stability?
No, LT6005HDHC#PBF is unity-gain stable and does not require external compensation components. It is characterized to remain stable with capacitive loads up to 500pF, including direct connection to ADC input capacitors and long PCB traces - simplifying layout and eliminating tuning iterations in production.
How is the exposed thermal pad on LT6005HDHC#PBF connected?
The exposed pad (Pin 17) of LT6005HDHC#PBF is internally connected to V– and must be soldered to a PCB copper pour tied to the V– net. This connection is mandatory for thermal management (reducing θJA from 160°C/W to ~65°C/W with 2cm² copper) and electrical noise suppression - leaving it unconnected degrades PSRR and thermal reliability.
Is LT6005HDHC#PBF pin-compatible with other LT6005 variants?
Yes, LT6005HDHC#PBF shares identical pinout and footprint with all LT6005 DFN variants (e.g., LT6005IDHC#PBF, LT6005CDHC#PBF) and the SSOP-packaged LT6005HGN#PBF. However, the DFN package has different thermal characteristics and requires distinct reflow profile validation versus SSOP.
