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 ±5 V. The THS4275 offers the same performance as the THS4271 with the addition of a 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.

Designers using the THS4271 are rewarded with higher dynamic range over a wider frequency band without the stability concerns of decompensated amplifiers. The devices are available in SOIC, MSOP with PowerPAD, and leadless MSOP with PowerPAD™ packages.

The THS4271 and THS4275 may have low-level oscillation when the die temperature (also known as the junction temperature) exceeds +60°C.
