The THS4271 and THS4275 are low-noise, high slew rate, unity gain stable voltage feedback amplifiers designed to run from supply voltages as low as 5 V and as high as 15 V. The THS4275 offers the same performance as the THS4271 with the addition of power down capability. The combination of low-noise, high slew rate, wide bandwidth, low distortion, and unity gain stability make the THS4271 and THS4275 high performance devices across multiple ac specifications.
