The LT6200/LT6201 are single and dual ultralow noise, rail-to-rail input and output unity gain stable op amps that feature 0.95nV/√Hznoise voltage. These amplifiers combine very low noise with a 165MHz gain bandwidth, 50V/μs slew rate and are optimized for low voltage signal conditioning systems. A shutdown pin reduces supply current during standby conditions and thermal shutdown protects the part from overload conditions.The LT6200-5/LT6200-10 are single amplifiers optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6200 family maintains its performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V.For compact layouts the LT6200/LT6200-5/LT6200-10 are available in the 6-lead ThinSOT™and the 8-pin SO package. The dual LT6201 is available in an 8-pin SO package with standard pinouts as well as a tiny, dual fine pitch leadless package (DFN). These amplifiers can be used as plug-in replacements for many high speed op amps to improve input/output range and noise performance.ApplicationsTransimpedance AmplifiersLow Noise Signal ProcessingActive FiltersRail-to-Rail Buffer AmplifiersDriving A/D Converters
