THS4032 - Texas Instruments

THS4032 100MHz Low-Noise High-Speed Amplifiers

The THS4031 and THS4032 (THS403x) are ultra-low voltage noise, high-speed voltage feedback amplifiers that are an excellent choice for applications requiring low voltage noise, including communications and imaging. The single-amplifier THS4031 and the dualamplifier THS4032 offer very good AC performance with 100MHz bandwidth (G = 2), 100V/μs slew rate, and .
