Product details
Overview
LT1882HS#PBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail output, picoamp-input precision operational amplifier optimized for high-accuracy signal conditioning in harsh-temperature industrial and aerospace systems. It delivers 50 μV max input offset voltage, 200 pA max input bias current, rail-to-rail output swing within 40 mV of V– and 220 mV of V+, and operates across –40°C to 125°C. It is used in thermocouple amplifiers and bridge transducer conditioners where low drift and ultra-low input current are critical.
For engineers reviewing the LT1882HS#PBF datasheet, LT1882HS#PBF pinout, LT1882HS#PBF application, or LT1882HS#PBF equivalent, key selection criteria include guaranteed performance over –40°C to 125°C, input offset voltage drift ≤0.8 μV/°C, capacitive load drive up to 1000 pF at unity gain, and matching specifications between internal amplifiers A/D and B/C.
Technical Context
The LT1882HS#PBF implements a precision bipolar input stage with on-chip input bias current cancellation, enabling ultralow 200 pA max IB while maintaining matched performance across all four amplifiers. Its rail-to-rail output stage uses complementary common-emitter followers to achieve 40 mV low-side and 220 mV high-side saturation voltages under load.
It supports single-supply operation from 2.7 V to 36 V (fully specified from 5 V to ±15 V), features 120 dB minimum CMRR and PSRR, and maintains stability driving 1000 pF loads in unity-gain follower configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤125 μV over –40°C to 125°C - ensures baseline DC accuracy in wide-temperature sensor interfaces |
| Input Bias Current | ≤600 pA over –40°C to 125°C - preserves gain accuracy with >10 MΩ source impedances |
| Offset Drift | ≤0.8 μV/°C - limits thermal-induced error to <100 μV across full operating range |
| Output Swing | Within 40 mV of V– and 220 mV of V+ at 1 mA load - enables true single-supply operation down to 3 V |
| Supply Range | 2.7 V to 36 V total - supports battery-powered, industrial 24 V, and dual ±15 V systems |
| Capacitive Load Drive | Stable with 1000 pF at AV = 1 - eliminates need for isolation resistors in DAC output buffers |
| Gain Bandwidth | 0.35 MHz - sufficient for 16-bit DAC settling and low-frequency sensor signal chains |

| Thermocouple Amplification | Bridge Transducer Conditioning |
|---|---|
Use Scenario: Amplifying microvolt-level thermocouple outputs (e.g., Type K, J) in furnace controllers and environmental monitoring systems operating from –40°C to 125°C ambient. IC Role / Device Role / Timing Role: Precision DC-coupled instrumentation amplifier front-end with cold-junction compensation interface. Use Value: 200 pA max input bias current prevents voltage drop across high-impedance thermocouple wires; 0.8 μV/°C drift minimizes calibration drift over temperature. | Use Scenario: Signal conditioning for strain-gauge or pressure-sensor Wheatstone bridges in industrial weigh scales and hydraulic sensors. IC Role / Device Role / Timing Role: Low-noise, matched quad op amp configured as two differential amplifiers for bridge excitation and output amplification. Use Value: Matched offset and bias current between A/D and B/C channels ensure common-mode rejection >100 dB; rail-to-rail output maximizes ADC input range. |
| 16-Bit DAC Output Buffer | Battery-Powered Precision Instrumentation |
Use Scenario: Buffering voltage-output DACs (e.g., LTC1597) in programmable power supplies and automated test equipment requiring monotonic 16-bit linearity. IC Role / Device Role / Timing Role: Unity-gain stable output driver with 1000 pF capacitive load capability. Use Value: Eliminates need for external isolation resistors; 40 mV output swing to V– allows full 0–4.096 V DAC range on +5 V/0 V supplies. | Use Scenario: Portable gas analyzers and handheld multimeters using high-impedance pH or ion-selective electrodes. IC Role / Device Role / Timing Role: Ultra-low-power, low-input-current signal conditioner operating from coin-cell or Li-ion batteries. Use Value: 0.65 mA max supply current per amplifier extends battery life; 2.7 V minimum supply enables operation down to end-of-life battery voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1882IS#PBF | Same quad architecture and pinout, but rated only to 85°C operating temperature; lower cost. | Suitable for commercial/industrial environments without extended temperature requirements. | Select LT1882IS#PBF when ambient temperature stays below 85°C and cost sensitivity outweighs extended-range assurance. |
| ADA4522-4ARZ | Zero-drift architecture; 0.3 μV max offset, 0.005 μV/°C drift, but higher 1.2 mA supply current and 3 MHz GBW. | Better DC accuracy for lab-grade instruments; less suitable for low-power or high-capacitive-load applications. | Choose ADA4522-4ARZ only when sub-microvolt offset and near-zero drift are mandatory, and 1000 pF load drive is not required. |
Compared with LT1882IS#PBF, LT1882HS#PBF guarantees full specification over –40°C to 125°C and offers superior capacitive load drive; compared with ADA4522-4ARZ, it trades zero-drift performance for lower power, wider supply range, and proven 1000 pF stability - making it optimal for ruggedized embedded sensor nodes.

FAQ
What is the guaranteed operating temperature range for LT1882HS#PBF?
The LT1882HS#PBF is guaranteed to operate from –40°C to 125°C, with full electrical specifications validated across this extended industrial temperature range. This makes LT1882HS#PBF suitable for under-hood automotive sensors, downhole oilfield tools, and military-grade portable instrumentation where ambient extremes are expected.
Does LT1882HS#PBF support single-supply operation?
Yes, LT1882HS#PBF supports true single-supply operation from 2.7 V to 36 V total supply. Its rail-to-rail output swings to within 40 mV of V– and 220 mV of V+, enabling full-scale signal handling on +5 V/0 V or +3.3 V/0 V supplies - ideal for battery-powered systems interfacing with 12-bit or 16-bit ADCs.
Can LT1882HS#PBF drive a 1000 pF load in unity-gain configuration?
Yes, LT1882HS#PBF is explicitly characterized and guaranteed stable driving 1000 pF capacitive loads in unity-gain follower mode, as confirmed in the datasheet's "Stable at AV = 1, CL = 1000 pF" feature list and Figure G10–G11. This eliminates external isolation resistors when buffering DAC outputs or long PCB traces.
How does LT1882HS#PBF compare to LT1882MP in terms of temperature rating?
LT1882HS#PBF is rated for –40°C to 125°C operation, while LT1882MP extends the lower limit to –55°C for military and space applications. Both share identical electrical specs at overlapping temperatures, but LT1882MP undergoes additional screening and qualification for extended cold performance - making LT1882HS#PBF the optimal choice for standard high-temp industrial use without the cost premium.
What is the input common-mode voltage range for LT1882HS#PBF?
The input common-mode voltage range for LT1882HS#PBF is V– + 1.0 V to V+ – 1.0 V at 25°C, degrading slightly with temperature. This means inputs must remain ≥1 V above V– and ≤1 V below V+ to maintain linear operation - a limitation distinct from its rail-to-rail output capability, critical when designing single-supply sensor interfaces.
