THS4022 - Texas Instruments

THS4022 High-Speed Amplifiers

The THS4021 and THS4022 (THS402x) are ultra-low voltage noise, high-speed voltage-feedback amplifiers that are an excellent choice for applications requiring low voltage noise, including communication and imaging. The single-amplifier THS4021 and the dualamplifier THS4022 offer very good ac performance with a 290MHz closed-loop bandwidth, 470V/μs slew rate,.
