Product details
Overview
LT6200CS8-10#PBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail input/output, low-noise operational amplifier optimized for high-gain applications with 1.6GHz gain bandwidth, 0.95nV/√Hz input voltage noise at 100kHz, and 340V/µs slew rate. It operates from 2.5V to 12.6V supplies and is used in precision photodiode transimpedance amplifiers and high-speed signal conditioning.
For engineers reviewing the LT6200CS8-10#PBF datasheet, LT6200CS8-10#PBF pinout, LT6200CS8-10#PBF application, or LT6200CS8-10#PBF equivalent, key selection criteria include its 10× minimum stable gain configuration, shutdown functionality, SO-8 package compatibility, and guaranteed performance across 0°C to 70°C.
Technical Context
The LT6200CS8-10#PBF is a unity-gain unstable op amp specifically compensated for minimum closed-loop gain of 10, enabling higher bandwidth and slew rate versus the base LT6200. Its internal compensation ensures stability only when configured with AV ≥ 10, making it unsuitable for unity-gain buffers without external compensation.
It integrates rail-to-rail input stage using complementary bipolar input transistors and rail-to-rail output stage with Class AB drive capability delivering ±60mA minimum short-circuit current. The SHDN pin enables 1.35mA disabled supply current, with 180ns turn-on/off timing into 100Ω load.
Key Specifications

| Gain Bandwidth Product | 1.6GHz at AV ≥ 10 - enables high-frequency filtering and wideband amplification in >100MHz systems |
| Slew Rate | 340V/µs - supports fast settling of large-signal steps without distortion in high-speed ADC drivers |
| Input Voltage Noise | 0.95nV/√Hz at 100kHz - critical for low-noise photodiode and sensor front-end amplification |
| Supply Range | 2.5V to 12.6V - allows operation from single 3.3V or 5V rails up to split ±5V supplies |
| Output Swing | Rail-to-rail - delivers full dynamic range into low-voltage ADCs and data converters |
| Shutdown Current | 1.35mA max - reduces power in standby mode while retaining fast wake-up capability |

FAQ
What is the minimum stable gain for LT6200CS8-10#PBF?
The LT6200CS8-10#PBF is internally compensated for minimum closed-loop gain of 10. It is not unity-gain stable; attempting AV < 10 risks oscillation. Stability is guaranteed only when configured with AV ≥ 10, as confirmed in the datasheet's Gain Bandwidth table and compensation notes. This distinguishes LT6200CS8-10#PBF from the base LT6200 (AV ≥ 1 stable) and LT6200-5 (AV ≥ 5 stable).
Does LT6200CS8-10#PBF support rail-to-rail input and output operation?
Yes, LT6200CS8-10#PBF supports true rail-to-rail input common-mode range (including both supply rails) and rail-to-rail output swing. At VS = 5V and ISINK/ISOURCE = 20mA, output voltage swing is within 150mV of each rail. Input stage uses complementary bipolar transistors to achieve this, enabling direct interfacing with sensors and ADCs operating at low supply voltages.
What is the typical input voltage noise of LT6200CS8-10#PBF and at what frequency is it specified?
The LT6200CS8-10#PBF has a typical input voltage noise density of 0.95nV/√Hz at 100kHz, as specified in the Electrical Characteristics table under "en" parameter. This value is measured at VS = 5V and is representative of its low-noise performance in high-frequency signal chains such as photodiode amplifiers and RF receiver IF stages.
Can LT6200CS8-10#PBF be used with a single 3.3V supply?
Yes, LT6200CS8-10#PBF operates from a minimum supply voltage of 2.5V, making it fully compatible with 3.3V single-supply systems. At VS = 3.3V, it maintains rail-to-rail input/output swing, 0.95nV/√Hz noise, and functional shutdown control. Performance specifications (e.g., GBW, slew rate) are characterized down to 3V, ensuring reliable operation across the full 2.5V–12.6V range.
What is the purpose of the NC pins (pins 5 and 8) on LT6200CS8-10#PBF?
Pins 5 and 8 on LT6200CS8-10#PBF are No Connect (NC) terminals - internally unconnected and electrically isolated. They must be left floating or tied to V– (pin 4) per Linear Technology's layout recommendations to avoid parasitic coupling. These pins are not intended for thermal relief or grounding; improper connection may degrade noise or stability performance of the LT6200CS8-10#PBF.
