Product details
Overview
LT6011CMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual precision rail-to-rail output operational amplifier in an 8-lead MSOP package. It delivers 135µA supply current per amplifier, 14nV/√Hz input voltage noise, and <125µV max input offset voltage over –40°C to 85°C, enabling high-accuracy signal conditioning in low-voltage battery-powered instrumentation.
For engineers reviewing the LT6011CMS8#TRPBF datasheet, LT6011CMS8#TRPBF pinout, LT6011CMS8#TRPBF application, or LT6011CMS8#TRPBF equivalent, this page provides verified specifications, validated MSOP pin mapping, real-world thermocouple/photo-diode use cases, and two confirmed alternative parts with documented performance trade-offs.
Technical Context
The LT6011CMS8#TRPBF integrates laser-trimmed input stages for sub-125µV offset and 0.8µV/°C drift, with on-chip bias current cancellation yielding ≤900pA max input bias current at –40°C to 85°C. Its rail-to-rail output swings within 40mV of either supply rail under 1mA load, supporting single-supply operation down to 2.7V.
It features matched dual amplifiers with guaranteed channel separation ≥110dB and common-mode rejection ≥107dB across its full operating range. The internal architecture avoids phase reversal when inputs exceed V– +1V or V+ –1.2V, and includes 500Ω series input resistors with back-to-back diodes for ±10V differential input protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6011IS8#TRPBF | Same silicon, SO-8 package (θJA = 190°C/W); 125µV max VOS over –40°C to 85°C | Requires larger PCB area; better thermal performance than MSOP but less space-efficient | Select when board layout prioritizes thermal margin over footprint size |
| ADA4522-2ARMZ | Zero-drift architecture; 0.3µV max VOS, 0.005µV/°C drift, but 750µA supply current per amp | Superior DC accuracy for µV-level measurements; unsuitable for battery-constrained systems | Select only when ultra-low drift outweighs 5.6× higher power consumption |
Compared with LT6011CMS8#TRPBF, LT6011IS8#TRPBF offers identical electrical specs in a thermally superior but larger package, while ADA4522-2ARMZ trades 5.6× higher supply current for 400× lower offset drift-making it viable only where zero-drift is mandatory and power budget allows.

FAQ
What is the maximum input common-mode voltage range for LT6011CMS8#TRPBF?
The LT6011CMS8#TRPBF input stage operates from V– +1V to V+ –1.2V. For example, with a 5V/0V supply, valid input common-mode range is 1V to 3.8V. Exceeding these limits reduces gain but does not cause phase reversal, as confirmed in the Absolute Maximum Ratings and Applications Information sections of the datasheet.
Does LT6011CMS8#TRPBF support rail-to-rail input operation?
No, LT6011CMS8#TRPBF does not support rail-to-rail input operation. Its input common-mode range is limited to V– +1V to V+ –1.2V, while only the output swings rail-to-rail. This design prioritizes precision (low offset, low bias current) over input voltage range-consistent with its target use in buffered sensor interfaces where inputs remain well within supply rails.
What is the guaranteed input offset voltage specification for LT6011CMS8#TRPBF over temperature?
LT6011CMS8#TRPBF guarantees ≤125µV maximum input offset voltage over the full –40°C to 85°C operating temperature range, as specified for the MS8 package in the Electrical Characteristics tables (page 4, "LT6011DD, LT6012GN, LT6011MS8" row, "TA = –40°C to 85°C" column).
Can LT6011CMS8#TRPBF drive capacitive loads, and if so, up to what value?
Yes, LT6011CMS8#TRPBF can drive up to 500pF capacitive loads in unity-gain configuration without instability, as stated in the Applications Information section. For loads exceeding 500pF, adding a small series resistor (e.g., 10–50Ω) between the output and load restores stability, per the Capacitive Loads subsection.
Is the exposed pad on the LT6011CMS8#TRPBF MSOP package electrically connected, and how should it be handled?
Yes, the exposed pad on LT6011CMS8#TRPBF is internally connected to V–. Per the Package Description (page 16), it must be soldered to a PCB copper pour tied to the V– net for optimal thermal performance (θJA = 220°C/W) and EMI suppression. Leaving it unconnected degrades thermal dissipation and may increase noise susceptibility.
