Product details
Overview
LT6200CS8#PBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input/output, ultralow-noise operational amplifier optimized for unity-gain stability. It delivers 0.95nV/√Hz input voltage noise at 100kHz, 165MHz gain bandwidth, and 50V/µs slew rate, operating from 2.5V to 12.6V supplies. It is used in precision photodiode amplifiers, transimpedance stages, and low-noise signal conditioning where wide dynamic range and full rail swing are critical.
For engineers reviewing the LT6200CS8#PBF datasheet, LT6200CS8#PBF pinout, LT6200CS8#PBF application, or LT6200CS8#PBF equivalent, key selection criteria include its 165MHz GBW at AV = 1, shutdown functionality with 180ns turn-on time, ±60mA output drive, and SO-8 package compatibility with legacy high-speed op amp footprints.
Technical Context
The LT6200CS8#PBF employs a proprietary bipolar input stage enabling both rail-to-rail common-mode input range (including both supply rails) and rail-to-rail output swing. Its internal architecture supports stable operation at unity gain while maintaining low distortion (–80dB HD2/HD3 at 1MHz into 100Ω) and high PSRR (68dB) across 2.5V–10V supplies.
It integrates active thermal shutdown and a dedicated SHDN pin that reduces supply current to ≤1.8mA (typical) when pulled low. The device maintains specified performance over 0°C to 70°C and is characterized for 3V, 5V, and ±5V operation - with input offset voltage drift as low as 2.5µV/°C and CMRR up to 90dB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-1ARMZ | Lower 1/f noise (120nV p-p), higher GBW (270MHz), but requires dual supply and no shutdown pin | Better for ultra-low-distortion video or RF IF stages; unsuitable for single-supply portable designs with power gating | Select when lowest broadband + 1/f noise is critical and shutdown is not required |
| OPA837IDBVR | Higher noise (1.1nV/√Hz), lower GBW (110MHz), but lower quiescent current (6.5mA vs 20mA) | Better for always-on, battery-constrained applications where moderate noise is acceptable | Select when optimizing for supply current over noise performance in continuous-operation systems |

FAQ
What is the maximum supply voltage for LT6200CS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6200CS8#PBF is 12.6V. It is fully specified and characterized for operation from 2.5V to 12.6V, including single 3V, 5V, and dual ±5V configurations. Exceeding 12.6V risks permanent damage per Absolute Maximum Ratings.
Does LT6200CS8#PBF support rail-to-rail input and output simultaneously?
Yes, LT6200CS8#PBF supports rail-to-rail input common-mode range (from V– to V+) and rail-to-rail output swing (within 150mV of each rail at 20mA load). This allows full utilization of supply headroom in single-supply systems, such as 3V sensor interfaces where input signals span 0–3V and output must drive ADC reference ranges.
What is the typical shutdown current of LT6200CS8#PBF?
The typical disabled supply current per amplifier for LT6200CS8#PBF is 1.35mA at 3V and 1.8mA at 5V when the SHDN pin is held ≤0.3V. This represents >90% reduction from normal operating current (~20mA), enabling effective power gating in duty-cycled instrumentation systems.
Can LT6200CS8#PBF drive a 100Ω load?
Yes, LT6200CS8#PBF guarantees ±60mA minimum output current, enabling direct driving of 100Ω loads with rail-to-rail swing. At 20mA sink/source, output voltage remains within 150–300mV of the respective supply rail - verified across temperature and supply conditions per Electrical Characteristics table.
Is LT6200CS8#PBF unity-gain stable?
Yes, LT6200CS8#PBF is explicitly designed and guaranteed unity-gain stable. It requires no external compensation and maintains phase margin >60° at AV = 1 across temperature and supply variations, as confirmed in Typical Performance Characteristics (Figure G22) and Applications section.
