Product details
Overview
LT6004CMS8#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, 2µV/°C drift, and drives 500pF loads - enabling high-accuracy signal conditioning in portable gas monitors and low-voltage sensor interfaces.
For engineers reviewing the LT6004CMS8#PBF datasheet, LT6004CMS8#PBF pinout, LT6004CMS8#PBF application, or LT6004CMS8#PBF equivalent, key selection criteria include ultralow quiescent current under 1.8V operation, guaranteed rail-to-rail performance across –40°C to 85°C, CMRR ≥100dB at 1.8V, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LT6004CMS8#PBF employs a complementary PNP/NPN input stage with automatic bias current cancellation, enabling rail-to-rail common-mode input range (0V to V+) while maintaining 90pA max input bias current. Its folded-cascode second stage and complementary drive output stage deliver true rail-to-rail output swing (≤100mV from rails) without phase reversal up to 9V below V–.
It integrates internal protection resistors (600kΩ) on both inputs and uses adaptive current steering to maintain stable 1µA supply current during power-up and output saturation - critical for systems powered by coin cells or energy-harvesting sources where transient current spikes must be avoided.
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 max at 5V - enables >10-year battery life in always-on sensor nodes drawing <1µA system average. |
| Input Offset Voltage | 500µV max over –40°C to 85°C - ensures ≤0.5mV error in 10-bit ADC front-ends with 3.3V full-scale range. |
| Offset Drift | 2µV/°C typical - limits temperature-induced error to <250µV over 125°C ambient swing, critical for uncalibrated field instruments. |
| CMRR | 100dB min at 1.8V - rejects >99.99% of common-mode noise in low-voltage bridge sensor applications. |
| Capacitive Load Drive | 500pF - allows direct connection to ADC input capacitors or long PCB traces without external isolation resistors. |
| PSRR | 95dB min - suppresses supply ripple to <0.2% of VOS shift, essential for noisy switching regulator domains. |
Pinout & Package
LT6004CMS8#PBF is housed in an 8-lead plastic MSOP package (3mm × 3mm, 1.1mm height), with exposed pad connected to V– for thermal and EMI performance. Pin 1 is marked with dot; device orientation follows JEDEC MO-187.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail swing (≤100mV from V+, ≤50mV from V–) into 20kΩ load. |
| 2 | V– | Negative supply - exposed pad must be soldered to PCB ground plane for thermal stability and noise immunity. |
| 3 | +IN A | Inverting input of Amp A - accepts signals from V– to V+ with 90pA max bias current. |
| 4 | –IN A | Non-inverting input of Amp A - matched to +IN A for <100µV input offset voltage shift across common-mode range. |
| 5 | V+ | Positive supply - bypass with 0.01µF ceramic capacitor within 10mm for stability at 1.6V operation. |
| 6 | –IN B | Inverting input of Amp B - electrically isolated from Amp A; no crosstalk specified beyond PSRR/CMRR. |
| 7 | +IN B | Non-inverting input of Amp B - identical specs to +IN A; supports dual-channel differential sensing. |
| 8 | OUT B | Amplifier B output - independent rail-to-rail output with same drive capability and settling as OUT A. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8V systems - e.g., 0–1.8V sensor output digitized directly by 1.8V ADC without level-shifting. |
| Micropower startup | Maintains ≤1.6µA supply current during power-up and output saturation - prevents brownout in energy-harvesting circuits with <5µA available current. |
| Phase reversal protection | Prevents output polarity inversion when inputs are driven 9V below V– - eliminates false triggers in overvoltage fault monitoring circuits. |
| Input bias cancellation | Reduces effective IB to 90pA max across 0.3V to V+–0.3V common-mode range - minimizes offset errors in high-impedance pH or gas sensor interfaces. |
| Guaranteed 1.6V operation | Specified minimum supply validated down to 1.6V at –40°C to 85°C - supports direct integration with primary lithium (1.5V) or NiMH (1.2V) cells via boost-free architecture. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2050CMS8#PBF | Zero-drift architecture; 0.5µV VOS max, 0.015µV/°C drift; 25µA IQ; 3MHz GBW | Higher precision required for DC-coupled strain gauge bridges; not suitable for <2µA power budgets | Select LTC2050CMS8#PBF only when sub-µV offset and near-zero drift outweigh 15× higher supply current. |
| MAX44260ASA+T | 1.8V min supply; 1.2µA IQ; 100µV VOS max; 12-bit INL-compatible; no 1.6V guarantee | Targeted at 12-bit ADC interfaces where 100µV VOS suffices; lacks –40°C to 125°C H-grade option | Choose MAX44260ASA+T for cost-sensitive 12-bit systems needing guaranteed 1.8V start-up but not 1.6V operation. |
Compared with LTC2050CMS8#PBF and MAX44260ASA+T, the LT6004CMS8#PBF uniquely balances 1.6V operability, 1µA-class quiescent current, and 500µV precision - making it the only dual op amp qualified for ultra-low-voltage, long-life sensor nodes requiring guaranteed performance at end-of-battery voltage.

FAQ
What is the minimum supply voltage guaranteed for LT6004CMS8#PBF operation?
The LT6004CMS8#PBF is fully specified and guaranteed to operate down to 1.6V across the commercial (0°C to 70°C) and industrial (–40°C to 85°C) temperature ranges. This 1.6V minimum is validated for all key parameters including input offset voltage, CMRR, and rail-to-rail output swing - enabling direct use with aging primary lithium cells or low-voltage energy harvesters where supply may dip below 1.8V.
Does LT6004CMS8#PBF support rail-to-rail input and output simultaneously?
Yes, the LT6004CMS8#PBF supports true rail-to-rail input (V– to V+) and output (within 100mV of V+, within 50mV of V–) simultaneously under all specified conditions. Its dual-input-stage architecture (PNP+NPN) and complementary drive output stage enable this behavior across the full 1.6V to 16V supply range and –40°C to 85°C temperature range - verified in the datasheet's "Rail-to-Rail Characteristics" section and Figure 1 schematic.
What is the maximum capacitive load the LT6004CMS8#PBF can drive without instability?
The LT6004CMS8#PBF is characterized to drive up to 500pF capacitive loads while maintaining ≥45° phase margin and monotonic step response - confirmed in the "Capacitive Load Handling" plot (Figure 22) and "Overshoot vs Capacitive Load" graph (Figure 23) of the datasheet. For loads exceeding 500pF, a series isolation resistor (≥100Ω) is recommended between the output and capacitance to preserve stability.
How does LT6004CMS8#PBF handle input overvoltage conditions?
The LT6004CMS8#PBF incorporates 600kΩ series input resistors and phase reversal protection circuitry that prevents output polarity inversion when inputs are driven up to 9V below V–. Input current is limited to <10mA even when forced above V+, satisfying Absolute Maximum Rating constraints. However, sustained input voltages beyond V+ or below V– require external clamping diodes to prevent junction damage - as noted in the "Applications Information" section.
Is LT6004CMS8#PBF pin-compatible with other packages in the LT6004 family?
No, the LT6004CMS8#PBF (MSOP-8) is not pin-compatible with the LT6004CDD#PBF (3mm × 3mm DFN-8), despite sharing identical electrical specifications and functional pin assignments. The MSOP-8 uses standard JEDEC lead pitch (0.65mm) and gull-wing leads, while the DFN-8 has 0.5mm pitch and bottom-exposed thermal pad - requiring separate PCB footprints and reflow profiles. Always verify package-specific land patterns before layout.
