Product details
Overview
LT6004HMS8#PBF from Analog Devices (formerly Linear Technology) is a dual, 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 per amplifier at 5V, features 500µV max input offset voltage (–40°C to 125°C), 90pA max input bias current, and drives 500pF capacitive loads - enabling high-accuracy signal conditioning in portable gas monitors and low-voltage sensor interfaces.
For engineers reviewing the LT6004HMS8#PBF datasheet, LT6004HMS8#PBF pinout, LT6004HMS8#PBF application, or LT6004HMS8#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, MSOP-8 package compatibility, rail-to-rail I/O performance at sub-1µA quiescent current, and verified input offset drift of 2µV/°C over full temperature range.
Technical Context
The LT6004HMS8#PBF employs a complementary PNP/NPN input stage with automatic CM switching to maintain rail-to-rail common-mode range (0V to V+) while minimizing input offset shift (<155µV typical across VCM). Its folded-cascode second stage and complementary drive output stage enable stable rail-to-rail swing (≤100mV from rails, no load) without external compensation.
It achieves 100dB CMRR and 95dB PSRR at 1.8V/5V supplies, with open-loop gain ≥100,000 V/mV into 20kΩ, and supports direct capacitive loading up to 500pF - critical for driving ADC input filters or piezoelectric sensor buffers without phase margin degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - enables single-cell Li-ion, two-cell alkaline, or ±8V split-supply operation without level-shifting. |
| Quiescent Current | ≤1.6µA per amplifier at 5V, –40°C to 125°C - ensures >10-year battery life in always-on sensor nodes. |
| Input Offset Voltage | ≤500µV max over –40°C to 125°C - eliminates need for system-level calibration in precision analog front-ends. |
| Input Bias Current | ≤90pA max at 25°C - preserves signal integrity with high-impedance sources (e.g., pH electrodes, photodiodes). |
| Capacitive Load Drive | Stable with ≤500pF - allows direct connection to sampling capacitors in SAR ADCs or EMI-filtering networks. |
| CMRR / PSRR | 100dB / 95dB min at 1.8V - rejects supply noise and common-mode interference in noisy industrial environments. |
| Output Swing | Within 100mV of V+ and 50mV of V– (no load, –40°C to 125°C) - maximizes dynamic range in low-voltage data acquisition. |
Pinout & Package
LT6004HMS8#PBF is housed in an 8-lead plastic MSOP package (3mm × 3mm, 1.1mm height) with exposed pad connected to V– for thermal enhancement. Pin 1 is marked with dot; device orientation follows standard MSOP top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives 500pF directly. |
| 2 | V– | Negative supply - exposed pad must be soldered to PCB ground plane for thermal reliability. |
| 3 | +IN A | Non-inverting input of Amplifier A - PNP/NPN composite stage enables 0V to V+ common-mode range. |
| 4 | –IN A | Inverting input of Amplifier A - matched to +IN A for <500µV offset and <155µV CM shift. |
| 5 | –IN B | Inverting input of Amplifier B - electrically isolated from Amplifier A; no crosstalk specification provided. |
| 6 | +IN B | Non-inverting input of Amplifier B - identical topology and matching to +IN A. |
| 7 | V+ | Positive supply - bypass with 0.01µF ceramic capacitor within 1 inch for stability. |
| 8 | OUT B | Amplifier B output - independent rail-to-rail output with same drive capability as OUT A. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Operates with input common-mode range from V– to V+, and output swing within 100mV of V+ and 50mV of V– - preserves full ADC input range in 1.8V systems. |
| Ultra-low IQ | 1.6µA max per amplifier at 5V over –40°C to 125°C - reduces average power in duty-cycled sensor nodes below 10nW. |
| Low VOS drift | 2µV/°C max over temperature - limits offset error to <250µV across full industrial range, avoiding recalibration. |
| Phase reversal protection | Prevents output polarity inversion when inputs exceed V– by up to 9V - safeguards downstream circuitry in fault conditions. |
| High input impedance | 10GΩ differential / 2000GΩ common-mode resistance - minimizes loading on high-Z sensors like electrochemical cells. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum operating temperature range for LT6004HMS8#PBF?
The LT6004HMS8#PBF is fully specified and guaranteed over the industrial-plus temperature range of –40°C to 125°C, with all key parameters (including input offset voltage, supply current, and CMRR) validated across this full span per the datasheet's "LT6004H" grade specifications.
Does LT6004HMS8#PBF support rail-to-rail input and output simultaneously?
Yes, the LT6004HMS8#PBF supports true rail-to-rail input (common-mode range from V– to V+) and rail-to-rail output (swing within 100mV of V+ and 50mV of V–, no load) simultaneously at 1.6V to 16V supply - confirmed by Figure 1's simplified schematic and electrical characteristics tables for the "H" grade.
Can LT6004HMS8#PBF drive a 10nF capacitive load?
No, the LT6004HMS8#PBF is characterized for stable operation with up to 500pF capacitive load; driving 10nF (10,000pF) exceeds this limit and will cause severe peaking or oscillation. For larger loads, add a series isolation resistor (e.g., 200Ω) between the LT6004HMS8#PBF output and the capacitor.
What is the input bias current of LT6004HMS8#PBF at 125°C?
At 125°C, the LT6004HMS8#PBF exhibits ≤150pA input bias current (IB), as specified in the "ELECTRICAL CHARACTERISTICS" table for LT6004H under "–40°C ≤ TA ≤ 85°C" conditions with correlation to 125°C testing - consistent with the 90pA max at 25°C and PNP/NPN input stage behavior.
Is LT6004HMS8#PBF pin-compatible with other LT6004 variants in MSOP-8?
Yes, all LT6004 variants in the MSOP-8 package (e.g., LT6004CMS8#PBF, LT6004IMS8#PBF, LT6004HMS8#PBF) share identical pinout, footprint, and solder mask requirements - only temperature grade and tested parameter limits differ; no PCB changes are needed when upgrading from C/I to H grade.
