Product details
Overview
LT1882IS#PBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail output, picoamp-input precision operational amplifier optimized for low-voltage, high-accuracy signal conditioning. It delivers 50 μV max input offset voltage, 200 pA max input bias current, and rail-to-rail output swing within 40 mV of V– and 220 mV of V+, operating from 2.7 V to 36 V total supply. It is used in thermocouple amplifiers, bridge transducer conditioners, and battery-powered instrumentation.
For engineers reviewing the LT1882IS#PBF datasheet, LT1882IS#PBF pinout, LT1882IS#PBF application, or LT1882IS#PBF equivalent, key selection considerations include its guaranteed –40°C to +85°C industrial temperature range, 14-pin SO package, matched amplifier performance (ΔVOS ≤ 175 μV), and stable unity-gain operation with up to 1000 pF capacitive load.
Technical Context
The LT1882IS#PBF integrates four independent precision op amps sharing a common 14-pin SO package, each featuring a bipolar input stage with on-chip bias current cancellation to achieve ultralow 200 pA max input bias current. Its input common-mode range is limited to V– + 1.0 V to V+ – 1.0 V, while output swing extends to within 40 mV of V– and 220 mV of V+ under load.
It achieves 0.35 MHz gain-bandwidth product and 0.15 V/μs slew rate at ±15 V, with open-loop voltage gain ≥ 500 V/mV into 10 kΩ. Channel separation exceeds 120 dB at 1 kHz, and it maintains stability without external compensation when driving 1000 pF in unity-gain follower configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1882CS#PBF | 0°C to +70°C temperature range; otherwise identical electrical specs and pinout | Restricted to commercial-grade environments (e.g., lab equipment, non-industrial IoT) | Select LT1882CS#PBF only if ambient operating temperature stays above 0°C |
| OP4177ARZ | Lower 60 μV max offset, higher 2.8 MHz GBW, but 1.2 mA per amplifier and no guaranteed 1000 pF drive | Better for higher-speed precision applications where load capacitance is <100 pF and power budget allows | Choose OP4177ARZ when settling time <10 μs is required and layout permits careful capacitive load management |
Compared with LT1882CS#PBF, the LT1882IS#PBF adds industrial-temperature qualification without trade-offs in precision or drive capability; versus OP4177ARZ, it trades bandwidth and offset for lower power and superior capacitive load tolerance-critical for unbuffered ADC drivers and compact PCB layouts.

FAQ
What is the maximum capacitive load the LT1882IS#PBF can drive stably in unity-gain configuration?
The LT1882IS#PBF is specified as unity-gain stable with up to 1000 pF capacitive load, as confirmed in the datasheet's "Stable at AV = 1, CL = 1000pF" feature list and Figure G10–G11. This eliminates the need for series isolation resistors in DAC output buffers or ADC input drivers, simplifying layout and preserving signal integrity.
Does the LT1882IS#PBF support true rail-to-rail input operation?
No, the LT1882IS#PBF does not support rail-to-rail input. Its input common-mode voltage range is specified as V– + 1.0 V to V+ – 1.0 V (min), meaning inputs must remain at least 1 V away from either supply rail. Exceeding this range causes gain collapse but no phase reversal, as noted in the Applications Information section.
What is the guaranteed operating temperature range for the LT1882IS#PBF?
The LT1882IS#PBF is guaranteed to operate over the industrial temperature range of –40°C to +85°C, as explicitly stated in the Absolute Maximum Ratings table and Order Information section. This qualifies it for use in factory automation, test equipment, and outdoor sensor nodes where ambient extremes are expected.
How does the LT1882IS#PBF compare to the LT1884/LT1885 in terms of speed and precision?
The LT1882IS#PBF trades speed for enhanced precision and capacitive drive: it offers lower input bias current (200 pA vs. ~500 pA), better offset voltage (50 μV vs. 75 μV), and stable 1000 pF drive, but reduced gain-bandwidth (0.35 MHz vs. 12 MHz) and slew rate (0.15 V/μs vs. 3 V/μs) compared to the LT1884/LT1885. It is optimized for DC–100 kHz precision, not high-speed signal paths.
Can the LT1882IS#PBF be used with a single 3.3 V supply?
Yes, the LT1882IS#PBF operates from a total supply voltage as low as 2.7 V, making it fully compatible with single 3.3 V supplies. Its rail-to-rail output swings to within 40 mV of ground and 220 mV of 3.3 V, delivering >2.9 V of usable output range-ideal for interfacing with 12-bit and 16-bit SAR ADCs in portable instrumentation.
