Product details
Overview
LT6202CS8#PBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input and output, ultralow-noise operational amplifier optimized for precision signal conditioning in low-power systems. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, 25V/µs slew rate, and operates from 2.5V to 12.6V supply with 2.5mA supply current per amplifier - enabling high-fidelity analog front-ends in battery-powered data acquisition.
For engineers reviewing the LT6202CS8#PBF datasheet, LT6202CS8#PBF pinout, LT6202CS8#PBF application, or LT6202CS8#PBF equivalent, key selection criteria include its rail-to-rail I/O swing, 0°C to 70°C industrial temperature grade, 8-pin SO package compatibility, and verified performance in driving ADC inputs and active filter stages without external level-shifting.
Technical Context
The LT6202CS8#PBF employs a unity-gain-stable voltage-feedback architecture with fully differential input stage and Class AB output stage, enabling rail-to-rail common-mode input range (including both supply rails) and rail-to-rail output swing under load. Its 1.9nV/√Hz noise floor is achieved via optimized transistor sizing and biasing, not external compensation.
It maintains stable operation across supply voltages from 2.5V to 12.6V and exhibits <–80dBc harmonic distortion at 1MHz - confirming suitability for wide-dynamic-range, low-distortion applications such as DSL receivers and precision sensor interfaces where signal integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Voltage Density | 1.9nV/√Hz at 100kHz - enables sub-µV signal resolution in high-gain sensor amplifiers |
| Gain Bandwidth Product | 100MHz - supports stable closed-loop gain up to 10× at 10MHz or unity gain at full 100MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA376AIDR | Lower noise (0.95nV/√Hz), lower GBW (5.5MHz), higher supply current (760µA), same SO-8 package | Better for ultra-low-noise DC-coupled sensors; insufficient bandwidth for >1MHz active filters | Select when noise dominates over speed; avoid for high-frequency signal conditioning |
| AD8675ARZ | Higher precision (10µV VOS), lower noise (2.8nV/√Hz), higher supply current (3.5mA), same SO-8 package | Better for precision DC gain stages; higher noise limits use in high-gain AC-coupled paths | Select when offset and drift dominate; avoid when 1.9nV/√Hz noise floor is mandatory |
Compared with OPA376AIDR and AD8675ARZ, the LT6202CS8#PBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, and 2.5mA supply current in an industry-standard SO-8 footprint - making it optimal for wideband, low-power, high-SNR signal chains where all three parameters are simultaneously constrained.

FAQ
What is the maximum supply voltage rating for the LT6202CS8#PBF?
The LT6202CS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V. Operation beyond this risks permanent damage. For reliable long-term use, Analog Devices specifies functional operation from 2.5V to 12.6V, with full electrical characteristics guaranteed at 3V, 5V, and ±5V supplies. The LT6202CS8#PBF must never be subjected to reverse polarity or overvoltage conditions without external protection.
Does the LT6202CS8#PBF support rail-to-rail input and output simultaneously?
Yes, the LT6202CS8#PBF supports rail-to-rail input common-mode voltage (from V– to V+) and rail-to-rail output swing (within 240mV of V– and 325mV of V+ at 20mA load) under the same operating conditions. This dual rail-to-rail capability eliminates level-shifting components in single-supply designs - a key advantage confirmed in the device's Electrical Characteristics table and Pin Configuration diagrams for the S8 package.
What is the guaranteed input offset voltage specification for LT6202CS8#PBF over temperature?
The LT6202CS8#PBF guarantees a maximum input offset voltage of 0.7mV at TA = 25°C and VS = 5V, VCM = half supply. Over the full 0°C to 70°C commercial temperature range, the max VOS rises to 1.7mV (at 3V supply, VCM = half supply) per the "l"-marked specifications in the datasheet. Input offset voltage drift is specified at 3.0–9.0µV/°C, enabling accurate DC error budgeting in precision applications.
Can the LT6202CS8#PBF drive a 100Ω load directly?
No - the LT6202CS8#PBF is not rated to drive a 100Ω load continuously. Its output can source/sink ≥30mA, implying a minimum resistive load of ~167Ω at ±5V supply (|VOUT| ≤ 5V). Driving 100Ω would require ≥50mA, exceeding the device's short-circuit current limit (±30mA) and risking thermal shutdown or reliability degradation. For 100Ω loads, use a buffer stage or select a higher-output-current amplifier like the LT6200.
Is the LT6202CS8#PBF pin-compatible with standard SO-8 op amps like the OP27 or AD820?
No - the LT6202CS8#PBF uses a nonstandard SO-8 pinout with three no-connect (NC) pins (pins 5, 6, and 8), unlike conventional dual-op-amp SO-8 footprints. Its pin 1 is OUT, pin 2 is –IN, pin 3 is +IN, pin 4 is V–, pin 7 is V+, and pins 5/6/8 are NC. Substituting into existing OP27 or AD820 layouts will cause misconnection and circuit failure unless board layout is revised to match the LT6202CS8#PBF's unique pin map.
