Product details
Overview
LT6201IS8#PBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, ultralow-noise operational amplifier in an 8-pin SO package, featuring 0.95nV/√Hz input voltage noise at 100kHz, 165MHz gain bandwidth at unity gain, and 50V/µs slew rate. It operates from 2.5V to 12.6V supplies and supports precision low-noise signal conditioning in single- or dual-supply configurations - ideal for photodiode transimpedance amplifiers and high-resolution ADC drivers.
For engineers reviewing the LT6201IS8#PBF datasheet, LT6201IS8#PBF pinout, LT6201IS8#PBF application, or LT6201IS8#PBF equivalent, key selection criteria include confirmed rail-to-rail I/O swing, shutdown functionality with 180ns turn-on/off timing, guaranteed –40°C to +85°C operation, and verified 165MHz GBW performance at AV = 1 under ±5V and 5V/0V supply conditions.
Technical Context
The LT6201IS8#PBF implements a dual-channel, unity-gain-stable voltage-feedback architecture optimized for low-voltage, high-fidelity signal paths. Its input stage uses complementary bipolar transistors enabling rail-to-rail common-mode input range and low input bias current (±40µA typical), while the output stage delivers ±60mA minimum drive capability with rail-to-rail swing under 20mA load.
It integrates independent shutdown control per amplifier (SHDN pin active-low), thermal shutdown protection, and operates across supply voltages from 2.5V to 12.6V. Performance is fully specified over –40°C to +85°C, with matching parameters (e.g., CMRR match ≥75dB, VOS match ≤2mV) validated for dual-amplifier correlation in instrumentation and differential signal chains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-2ARMZ | Lower noise (0.9nV/√Hz), higher GBW (270MHz), but requires ≥±4.5V supplies; no shutdown function. | Better for high-speed, high-SNR applications with symmetric supplies; unsuitable for 3V single-supply or power-gated systems. | Select when absolute lowest noise and highest bandwidth are prioritized over supply flexibility and power management. |
| OPA211AIDR | Lower noise (1.1nV/√Hz), lower quiescent current (3.6mA/ch), but only 45MHz GBW and no rail-to-rail output. | Preferred for battery-powered precision instrumentation where speed <10MHz suffices and supply headroom permits output swing limitation. | Choose for ultra-low-power, moderate-bandwidth applications where output swing beyond 1V from rails is acceptable. |
Compared with ADA4898-2ARMZ and OPA211AIDR, the LT6201IS8#PBF uniquely combines rail-to-rail I/O, integrated shutdown, 165MHz GBW, and 0.95nV/√Hz noise in a single 8-pin SO package rated for –40°C to +85°C - making it optimal for compact, low-voltage, high-fidelity dual-channel signal chains requiring thermal and power management.

FAQ
What is the guaranteed operating temperature range for the LT6201IS8#PBF?
The LT6201IS8#PBF is fully specified and guaranteed to operate from –40°C to +85°C. This industrial temperature rating is validated across all key parameters including gain bandwidth, noise, offset voltage, and channel matching - unlike commercial-grade variants (e.g., LT6201CS8#PBF) which are only tested from 0°C to 70°C. The "I" grade designation confirms extended-temperature qualification.
Does the LT6201IS8#PBF have a dedicated shutdown pin?
No - the LT6201IS8#PBF in the 8-pin SO package does not include a physical SHDN pin. Shutdown functionality is implemented externally via logic-level control of the V– and/or V+ supplies, or by grounding inputs and disabling bias networks. The DFN-packaged LT6201CDD#PBF does feature a dedicated SHDN pin, but the SO-8 variant relies on system-level power gating. This is confirmed in the Pin Configuration diagrams and Absolute Maximum Ratings table.
What is the maximum supply voltage the LT6201IS8#PBF can withstand?
The LT6201IS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V, as stated in the Absolute Maximum Ratings table. Operation is fully specified from 2.5V to 12.6V total supply, including single-supply (e.g., 5V/0V) and split-supply (e.g., ±5V) configurations. Exceeding 12.6V risks permanent damage, regardless of temperature or duration.
How does the LT6201IS8#PBF compare to the LT6200 in terms of noise and bandwidth?
The LT6201IS8#PBF shares identical core specifications with the single-channel LT6200: both deliver 0.95nV/√Hz input voltage noise at 100kHz and 165MHz gain bandwidth at unity gain. The LT6201IS8#PBF integrates two such amplifiers in one SO-8 package with matched performance (e.g., VOS match ≤2mV, CMRR match ≥75dB), enabling space-constrained dual-path designs without performance trade-offs versus discrete LT6200 implementations.
Is the LT6201IS8#PBF pin-compatible with other op amps in SO-8 packages?
The LT6201IS8#PBF follows the industry-standard dual-op-amp SO-8 pinout (OUT A, –IN A, +IN A, V–, V+, OUT B, –IN B, +IN B), making it compatible with legacy footprints for devices like the OP27, AD822, and LM358. However, due to its rail-to-rail input/output architecture, higher speed, and different bias requirements, direct substitution requires verification of loop stability, supply sequencing, and noise performance - it is not a drop-in replacement without circuit review.
